Express Delivery Bag and Structural Configuration Thereof

The present invention relates generally to an express delivery bag, and more particularly to an express delivery bag and its structural configuration that can reduce transportation costs, is suitable for continuous production, can be tracked and theft-proofed during the logistics process.

An express delivery bag is a type of security bag designed to protect products or documents (such as cash, sensitive documents, important credentials, online merchandise, and other items requiring confidentiality and integrity). An express delivery bag includes an outer layer made of plastic material and an adhesive (such as double-sided tape). The adhesive is used to seal the plastic material of the outer layer near the bag opening, thereby closing the bag. Consequently, once the bag is opened, the adhesive leaves noticeable damage or marks on the plastic material near the bag opening, helping to prevent unauthorized individuals from opening the bag and ensuring that its contents remain unaltered or tampered with, thereby increasing confidentiality.

Bubble-type express delivery bags have a bubble layer attached to the inner side of the plastic material outer layer to provide better cushioning performance for protecting items packaged inside the bag, especially for packaging online merchandise. The cushioning performance of the bubble layer prevents damage to online merchandise during transportation caused by collisions. However, the bubble layer of bubble-type express delivery bags contains numerous bubbles to reduce the impact of external forces on the packaged items. These bubbles have a certain volume, leading to increased transportation costs and hindering the application of such products.

In addition, with the booming development of online shopping and the increasing demands of logistics, the lack of traceability and anti-theft measures for the products or documents protected by express delivery bags is also one of the main challenges faced by the industry.

The present invention provides an express delivery bag and structural configuration thereof that can reduce transportation costs, is suitable for continuous production, can be tracked and theft-proofed during the logistics process, aiming to address the aforementioned issues.

The present invention provides an express delivery bag, which includes an airbag film layer, a plastic bag film layer, and a plurality of perforation lines. The airbag film layer has at least one airbag and a main flow runner, wherein the main flow runner communicates with the at least one airbag, and the main flow runner is adapted to allow an air to be injected into the at least one airbag, changing the at least one airbag from a flat state to an inflated state. The plastic bag film layer wraps the airbag film layer within by folding. The perforation lines run through the plastic bag film layer and the airbag film layer wrapped in the plastic bag film layer, wherein a separable structural configuration is defined between two neighboring ones of the perforation lines.

The present invention also provides a structural configuration of an express delivery bag, wherein the structural configuration includes a plastic bag film layer having a first lateral edge and a second lateral edge corresponding to each other, and an airbag film layer having a third lateral edge and a fourth lateral edge corresponding to each other, wherein the airbag film layer has at least an airbag and a main flow runner. The main flow runner communicates with the at least one airbag, and is adapted to allow an air to enter the at least one airbag, changing the at least one airbag from a flat state to an inflated state. The plastic bag film layer and the airbag film layer are folded together along a folding line, such that the first lateral edge overlaps the third lateral edge to form a first sealing region, and the second lateral edge overlaps the fourth lateral edge to form a second sealing region; the plastic bag film layer and the airbag film layer are sealed through the first sealing region and the second sealing region, and the plastic bag film layer forms an outer bag, while the airbag film layer forms an inner bag; the inner bag has a containing space formed therein, and the inner bag is provided in the outer bag.

In summary, the airbag of the airbag film layer of the express delivery bag and the structural configuration of the present invention can change from the flat state to the inflated state after inflation. Therefore, during transportation, it is not necessary to inflate the airbag, allowing the express delivery bag and the structural configuration of the present invention to remain in the flat state, reducing the volume of the express delivery bag and the structural configuration during transportation, thereby reducing transportation costs. When it is desired to package items using the express delivery bag or the structural configuration of the present invention, the airbag can be inflated to change the express delivery bag and the structural configuration of the present invention to the inflated state, producing a buffering and protective effect. Additionally, the express delivery bag and the structural configuration of the present invention may have an identity authentication component, which can provide identity information, enabling the express delivery bag and the structural configuration to be identified, tracked, and statistically analyzed during the logistics process, or to have anti-theft functionality.

The term “non-return valve” mentioned in the text refers to a structure that allows air to pass in only one direction. Its specific structure can be exemplified by the “air valve device” disclosed in Taiwan Patent No. I440590. For the sake of brevity, further elaboration is omitted here.

Please refer tothrough.depicts a schematic view of a structural configuration′ of an express delivery bag according to the first embodiment of the present invention.illustrates the appearance and cross-sectional view of an airbag film layeras shown in.shows a schematic view of the first process step of an express delivery bagaccording to the first embodiment of the present invention.illustrates the second process step of an express delivery bagaccording to the first embodiment of the present invention.depicts the third process step of an express delivery bagaccording to the first embodiment of the present invention. Finally,illustrates the fourth process step of an express delivery bagaccording to the first embodiment of the present invention.

As shown in, the structural configuration′ of the express delivery bag includes an airbag film layerand a plastic bag film layer. The airbag film layerincludes at least one airbagand a main flow runner. The main flow runnerconnects to at least one airbag, and it is used to supply air into at least one airbag, causing the airbag to change from a flat state to an inflated state. In this embodiment, the airbag film layerhas multiple airbags, but the present invention is not limited to this; for example, the airbag film layercan also have only one airbag, depending on actual requirements.

Below, the process of the express delivery bagand its structural configuration′ according to the first embodiment of the present invention is explained. As shown in, firstly, the plastic bag film layeris provided. The plastic bag film layeris pulled out from a plastic bag film layer reeland passed through a set of tension rollersto keep it flat. Next, the airbag film layeris overlaid onto the plastic bag film layer. The airbag film layeris pulled out from an airbag film layer reeland similarly passed through a set of tension rollersto keep it flat. The airbag film layer, after passing through the tension rollers, changes direction at a turning roller, and then passes simultaneously with the plastic bag film layerthrough a set of overlapping rollers, thereby completing the overlapping of the plastic bag film layerand the airbag film layer.

Next, as shown in, the overlapped plastic bag film layerand airbag film layerpass through a triangular folding piece. As they pass through this folding piece, the overlapped plastic bag film layerand airbag film layerfold along a folding line FL together. At this point, the plastic bag film layerfolds over the airbag film layer. Furthermore, another set of tension rollersis used to keep the folded plastic bag film layerand airbag film layerflat, and a set of pressing rollersis used to make the folded plastic bag film layerand airbag film layeradhere more tightly.

As shown in, the plastic bag film layerhas a first top edgeand a second top edgecorresponding to each other. The airbag film layerhas a third top edgeand a fourth top edgecorresponding to each other. As shown in, after the plastic bag film layerand airbag film layerare folded together along the folding line FL by the folding piece, the second top edgeof the plastic bag film layeris located between the first top edgeof the plastic bag film layerand the folding line FL, while the fourth top edgeof the airbag film layeris located between the third top edgeof the airbag film layerand the folding line FL. The third top edgeof the airbag film layeris positioned between the first top edgeand the second top edgeof the plastic bag film layer, and the main flow runneris located between the third top edgeand the folding line FL.

As shown in, after the plastic bag film layerand the airbag film layerare folded along the folding line FL, the present invention utilizes a sealing deviceand a perforation deviceto generate multiple edge-sealing structuresand multiple perforation linesrespectively. Each edge-sealing structureis used to secure the plastic bag film layerand the airbag film layertogether, and each perforation linecorresponds to one of the multiple edge-sealing structures. Each perforation lineis set through the plastic bag film layerand extends through the airbag film layerwrapped inside the plastic bag film layer, connecting the first top edgeof the plastic bag film layerwith the folding line FL. In this embodiment, the sealing devicecan be, for example, a heat sealing device, and the perforation devicecan be, for example, a perforation cutting machine, but the present invention is not limited to these. Additionally, when the plastic bag film layerand the airbag film layerare folded along the folding line FL and the edge-sealing structuresand perforation linesare generated, the plastic bag film layerand the airbag film layercan form an express delivery bag.

When the plastic bag film layerand the airbag film layerform an express delivery bag, the express delivery bagis not yet inflated and remains in the flat state, which significantly reduces the occupied volume of the express delivery bag. Furthermore, the express delivery bagin the flat state can be rolled up into an express delivery bag reel, as shown in. Similarly, the express delivery bag reel, due to the express delivery bagbeing in the flat state, significantly reduces the occupied volume, thereby facilitating the transportation of the express delivery bag reeland reducing the transportation costs of both the express delivery bag reeland the express delivery bag.

Furthermore, two neighboring perforation linescan define a structural configuration′ of an express delivery bag in between, as shown in, where the edge-sealing structuresform the sides of the structural configuration′, and the folding line FL forms the bottom thereof. The plastic bag film layerforms the outer bag of the structural configuration′, while the airbag film layerforms the inner bag. The inner bag forms a containing space, positioned within the outer bag. In summary, the structural configuration′ is a double-layered bag, with the outer bag formed by the plastic bag film layerand the inner bag formed by the airbag film layer. Both the outer bag and the inner bag of the structural configuration′ have the folding line FL as the bottom and the edge-sealing structuresas the sides.

It is worth mentioning that the perforation linesof the express delivery bagconnect the first top edgeof the plastic bag film layerto the folding line FL, thus linking the top and bottom edges of the express delivery bag. Since the perforation linespenetrate through both the plastic bag film layerand the airbag film layer, they weaken the structural integrity of both layers. Consequently, when one side of the express delivery bagis subjected to force, the plastic bag film layerand the airbag film layerare most likely to break apart at the location of the perforation line(where the structural strength is weaker), leading to the separation of the structural configuration′ from the express delivery bag. In other words, the express delivery bagof the present invention is a continuous bag containing multiple structural configurations′, each of which is delineated by perforation linesand can be torn off from the continuous bag independently to form a standalone bag. After the structural configuration′ is torn off from the continuous bag by the perforation line, the airbag film layerof the structural configuration′ can form a third lateral edgeand a fourth lateral edgecorresponding to each other, while the plastic bag film layercan form a first lateral edgeand a second lateral edge, which also correspond to each other.

In this embodiment, each edge-sealing structureis in a U-shaped configuration, meaning each edge-sealing structureincludes a left-edge sealing structure, a right-edge sealing structure, and an up-edge sealing structure. The left-edge sealing structureis located on one side of one of the multiple perforation lines, while the right-edge sealing structureis located on the other side of another perforation line. In other words, the left-edge sealing structureand the right-edge sealing structureare positioned on opposite sides of their corresponding perforation lines. The up-edge sealing structureis located between the left-edge sealing structureand the right-edge sealing structure. In this embodiment, the up-edge sealing structureconnects the left-edge sealing structureand the right-edge sealing structure.

Please refer tothrough.depicts a schematic view of the express delivery bagin the process of inflation according to the first embodiment of the present invention. In this embodiment, the airbag film layeralso includes multiple secondary flow runners. The number of secondary flow runnerscorresponds to the number of airbags, and each secondary flow runnerconnects the main flow runnerto one of the airbags. In this embodiment, the inflation device C also includes a heat sealing device A, a cutting device B, a nozzle C′, and a driving roller D. The nozzle C′ is used to spray air G, and the driving roller D is used to propel the express delivery bag. Due to the perspective,only depicts one roller, but in practice, those skilled in the art should understand that the driving roller D is composed of a pair of upper and lower rollers. By gripping and pulling with the upper and lower rollers, the express delivery bagis moved in the direction indicated by the arrow E in.

Continuing from the above, the express delivery bagis formed by driving the plastic bag film layerand the airbag film layerto overlap with each other using rollers. Then, they are folded by the folding piece, and finally, the overlapped and folded plastic bag film layerand airbag film layerare sealed and cut separately by the sealing deviceand the cutting device. Therefore, the width of each structural configuration′ is determined by the activation cycle of the sealing deviceand the cutting device, along with the speed of the rollers. That is, at the same roller speed, when the activation cycle of the sealing deviceand the cutting deviceis shorter, the width of each structural configuration′ is narrower; when the activation cycle of the sealing deviceand the cutting deviceis longer, the width of each structural configuration′ is wider.

In practice, since the airbagsand secondary flow runnerson the airbag film layerare evenly distributed, the positions of the perforation linesgenerated by the cutting devicewhen the overlapped and folded plastic bag film layerand airbag film layerpass through it vary depending on the actual width requirements of the structural configuration′. The positions of the perforation linesmentioned above can include the following three types:

Continuing from the above, since the perforation linespenetrate both the plastic bag film layerand the airbag film layer, when one perforation lineis located at positions such as Position One and Position Two, the main flow runner, secondary flow runner, and airbagcan communicate with the outside of the express delivery bagthrough the perforation line. Therefore, the up-edge sealing structureof the edge-sealing structureis adjacent to the bottom edgeof the main flow runneron the airbag film layer, and the up-edge sealing structureconnects the left-edge sealing structureand the right-edge sealing structure. In this way, the up-edge sealing structure, left-edge sealing structure, and right-edge sealing structureof the edge-sealing structurecan prevent the air G from entering the secondary flow runnerand the airbagpunctured by the perforation line, and from escaping to the outside of the express delivery bagthrough the perforation lineson the secondary flow runnerand the airbag.

In the present invention, the position of the up-edge sealing structureof the edge-sealing structureis not limited to the diagram illustrated in this embodiment. For example, the up-edge sealing structurecan also be positioned between the bottom edgeand a top edgeof the main flow runneron the airbag film layer. Additionally, the up-edge sealing structureconnects the left-edge sealing structureand the right-edge sealing structure. In this way, the up-edge sealing structure, left-edge sealing structure, and right-edge sealing structureof the edge-sealing structurecan also prevent the air G from entering the secondary flow runnerand the airbagpunctured by the perforation line, and from escaping to the outside of the express delivery bagthrough the perforation lineon the secondary flow runnerand the airbag. In other words, the structural design where the left-edge sealing structure, right-edge sealing structure, and up-edge sealing structuredo not completely seal the main flow runnerand can block the air G from entering the secondary flow runnerand the airbagpunctured by the perforation line, thereby preventing communication with the outside of the express delivery bagthrough the perforation lineon the secondary flow runnerand the airbag, falls within the scope of protection of the present invention.

As shown in, when the express delivery bagis driven by the driving roller D and moves in the direction of the arrow E towards the nozzle C′ of the inflation device C to enter the main flow runner, the air G sprayed out by the nozzle C′ of the inflation device C can enter the main flow runner. Then, it is directed through each secondary flow runnerinto the corresponding airbag, causing the airbagto change from the flat state to the inflated state. Next, as the express delivery bagcontinues to be driven by the driving roller D along the arrow E, the cutting device B can puncture the main flow runner. This allows the nozzle C′ to continue entering the main flow runnerso that subsequent express delivery bagsdriven out by the driving roller D from the express delivery bag reelcan be inflated. Additionally, after the inflation device C inflates the airbag, transforming it from the flat state to the inflated state, the driving roller D continues to move the inflated airbagtowards the heat sealing device A. This action causes the secondary flow runnerto pass through the heat sealing device A, where the heat sealing device A seals the secondary flow runnerthermally. Consequently, the secondary flow runnercan be sealed by the heat sealing device A to prevent the air G injected into the airbagfrom escaping through the secondary flow runner. It's worth mentioning that in other embodiments, the heat sealing device A can also be used to seal the airbagto prevent the air G injected into the airbagfrom escaping through the secondary flow runner. Ideally, the heat sealing device A seals the airbagnear the secondary flow runner, effectively preventing the air G from escaping through the secondary flow runneror the airbag. This sealing mechanism aims to prevent the dissipation of air G injected into the airbag, ensuring its inflation.

Please refer to, which depicts a schematic view of an express delivery bagand its structural configuration′ during the inflation process in the second embodiment of the present invention. The main difference between the express delivery bagand its structural configuration′ and the previously described express delivery bagand its structural configuration′ lies in that at least one of the plurality of edge-sealing structures′ of the express delivery bagis a ribbon-shaped edge-sealing structure. The top edgeof the ribbon-shaped edge-sealing structure is adjacent to the bottom edgeof the main flow runneror located between the bottom edgeand a top edgeof the main flow runner. In other words, the ribbon-shaped edge-sealing structure does not completely seal the main flow runner, falling within the scope of protection of the present invention. In this embodiment, all edge-sealing structures′ are ribbon-shaped edge-sealing structures, but the present invention is not limited to this. That is, the design where one or more edge-sealing structures′ are ribbon-shaped edge-sealing structures also falls within the scope of protection of the present invention. Components with the same reference numerals as those in the previous embodiment have the same structure. To avoid redundancy, their description is omitted here.

Please refer to, which illustrates a schematic view of an express delivery bagand its structural configuration′ during the inflation process in the third embodiment of the present invention. The main difference between the express delivery bagand its structural configuration′ and the previously described express delivery bagand its structural configuration′ lies in that the plurality of airbags′ in the express delivery bagare cylindrical. Components with the same reference numerals as those in the previous embodiments have the same structure. To avoid redundancy, their description is omitted here.

Please refer to, which illustrates a schematic view of an express delivery bagand its structural configuration′ during the inflation process in the fourth embodiment of the present invention. The main difference between the express delivery bagand its structural configuration′ and the previously described express delivery bagand its structural configuration′ lies in that the airbag film layerof express delivery bagadditionally includes multiple secondary non-return valves. The plurality of secondary non-return valvescorrespond to one of the multiple airbagsand one of the multiple secondary flow runners. The plurality of secondary non-return valvesare installed in one of the multiple secondary flow runners. The secondary non-return valvesare used to prevent the air G entering the airbagfrom escaping through the secondary flow runner. In this embodiment, the airbag film layercontains multiple secondary non-return valves, but the present invention is not limited thereto. The design of one or more secondary non-return valvesis within the scope of protection of the present invention. Components with the same reference numerals as those in the previous embodiments have the same structure. To avoid redundancy, their description is omitted here.

Please refer to, which illustrates a schematic view of an express delivery bagand its structural configuration′ in the fifth embodiment of the present invention. The main difference between express delivery bagand its structural configuration′ and the previously described express delivery bagand its structural configuration′ lies in the sealing structure. Express delivery bagis sealed by sealing deviceto form a first lateral-edge sealing structure, a second lateral-edge sealing structure, and a top edge sealing structure. The top edge sealing structureis adjacent to the bottom edgeof the main flow runner. One end of the first lateral-edge sealing structureis connected to the top edge sealing structureor located between the bottom edgeand the top edgeof the main flow runnerto form an air inletat one endof the main flow runner. One end of the second lateral-edge sealing structureis connected to the top edgeof the main flow runner, the top edge of the airbag film layer(i.e., the third top edge), or one of the top edges of the plastic bag film layer(i.e., the first top edge) to seal the other endof the main flow runner. Additionally, express delivery bagincludes multiple secondary non-return valves. The plurality of secondary non-return valvescorrespond to one of the multiple airbagsand one of the multiple secondary flow runners. The plurality of secondary non-return valvesare installed in one of the multiple secondary flow runners. In this embodiment, the airbag film layercontains multiple secondary non-return valves, but the present invention is not limited thereto. The design of one or more secondary non-return valvesis within the scope of protection of the present invention.

Furthermore, express delivery bagforms a continuous bag structure, which is then cut by a cutting devicebetween the first lateral-edge sealing structureand the second lateral-edge sealing structure. The cut express delivery bagcan thereby form independent bag structures (i.e., the structural configuration′). The top edge sealing structure, which is cut, is thus divided into two parts. Consequently, the plastic bag film layerof the structural configuration′ can have a first lateral edgeand a second lateral edge, which correspond to each other; and the airbag film layerof the structural configuration′ can have a third lateral edgeand a fourth lateral edge, which correspond to each other.

Furthermore, the third lateral edgeof the airbag film layerof the structural configuration′ overlaps with the first lateral edgeof the plastic bag film layer. After being sealed by the sealing deviceand cut by the cutting device, this overlap forms a first sealing region. The first sealing regionincludes a first top-edge sealing structure(part of the cut top-edge sealing structure) and a first lateral-edge sealing structure. The first top-edge sealing structureis adjacent to the bottom edgeof the main flow runner, and the end of the first lateral-edge sealing structureis connected to the top-edge sealing structureor located between the bottom edgeand the top edgeof the main flow runner, creating an air inletat the endof the main flow runner. Similarly, the fourth lateral edgeof the airbag film layeroverlaps with the second lateral edgeof the plastic bag film layer. After being sealed by the sealing deviceand cut by the cutting device, this overlap forms a second sealing region. The second sealing regionincludes a second top-edge sealing structure(another part of the cut top-edge sealing structure) and a second lateral-edge sealing structure. The second top-edge sealing structureis adjacent to the bottom edgeof the main flow runner, and the end of the second lateral-edge sealing structureis connected to the top edgeof the main flow runner, the top edge of the airbag film layer, or the top edge of the plastic bag film layer, thus sealing the other endof the main flow runner.

Continuing from the above, the plastic bag film layerof the structural configuration′ forms an outer bag, while the airbag film layerforms an inner bag. The inner bag contains a containing space for storing/packaging an item, and it is placed inside the outer bag. When the inner bag (i.e., the airbag film layerof the structural configuration′) is inflated, the air G can enter the main flow runnerthrough the air inletat the endof the main flow runner. Since the other endof the main flow runneris sealed by the second lateral-edge sealing structure, the air G entering the main flow runnercannot escape from the other endof the main flow runner. Instead, it enters the corresponding airbagthrough the secondary flow runners, causing the airbagto inflate.

In this way, the inner bag in the inflated state (i.e., the airbag film layerof the structural configuration′) can provide cushioning and protection for the item inside. It's worth noting that the secondary non-return valveslocated in the secondary flow runnersprevent the air from escaping from the secondary flow runnersafter inflating the airbag, allowing the airbagto maintain the inflated state. Additionally, the outer bag (i.e., the plastic bag film layerof the structural configuration′) can be made of plastic material. When the outer bag is opened, any visible damage or signs of tampering on the plastic material of the outer bag can be easily detected. This helps prevent unauthorized access to the bag and ensures that the item inside remains unaltered or unchanged.

Furthermore, please refer to, which illustrates another embodiment of the present invention, an express delivery bag″ and its structural configuration′. The main difference between express delivery bag″ and express delivery baglies in the manufacturing process. Express delivery bag″ does not use a cutting devicebut instead employs a perforation device. This means that adjacent pairs of structural configurations′ in express delivery bag″ are separated by perforation linescreated by the perforation device. As a result, the adjacent structural configurations′ in express delivery bag″ remain connected by perforation lines. When one side of express delivery bag″ is subjected to force, it is most likely to tear apart at the location of the perforation lines(i.e., the weakest structural points), causing the structural configurations′ to be torn away from express delivery bag″. Therefore, in this embodiment, express delivery bag″ is a continuous bag body containing multiple structural configurations′, each separated by perforation lines. These multiple structural configurations′ are delineated by perforation linesand can be torn away from the continuous bag body formed by express delivery bag″ along the perforation lines, thus becoming independent bags.

Please refer to, which illustrates a schematic view of the sixth embodiment of the present invention, a structural configuration′. The main difference between structural configuration′ and the previously described structural configuration′ lies in the absence of secondary non-return valves in the secondary flow runnersof structural configuration′. Instead, structural configuration′ includes a main non-return valve. The main non-return valveis positioned at the air inletat the endof the main flow runner. It functions to prevent the air G entering the airbagfrom escaping through the air inlet. Components with the same reference numbers as the previous embodiments have identical structures. To avoid repetition, further elaboration is omitted here.

Please refer to, which depicts a schematic view of the seventh embodiment of the present invention, an express delivery bagand its structural configuration′. The main difference between express delivery bagand its structural configuration′ and the previously described structural configuration′ lies in the configuration of the cut-out structural configuration′. The first sealing region′ of the structural configuration′ includes a first top-edge sealing structureand a first lateral-edge sealing structure′. The first top-edge sealing structureis adjacent to the bottom edgeof the main flow runner, while one end of the first lateral-edge sealing structure′ is connected to the top edgeof the main flow runner, the top edge (third top edge) of the airbag film layer, or the top edge (first top edge) of the plastic bag film layer, thereby sealing one endof the main flow runner. The second sealing regionof the structural configuration′ includes a second top-edge sealing structureand a second lateral-edge sealing structure. The second top-edge sealing structureis adjacent to the bottom edgeof the main flow runner, while one end of the second lateral-edge sealing structureis connected to the top edgeof the main flow runner, the top edge (third top edge) of the airbag film layer, or the top edge (first top edge) of the plastic bag film layer, thereby sealing the other endof the main flow runner.

The airbag film layeralso includes an air inlet′, which communicates with the main flow runnerand is located between the endand the other endof the main flow runnerin the express delivery bag. This means that the air inlet′ of the express delivery bagis not positioned at either endor the other endof the main flow runner. Additionally, the structural configuration′ includes a main non-return valve, which is positioned at the air inlet′. Therefore, the main non-return valveof the structural configuration′ is also not positioned at either endor the other endof the main flow runner. The main non-return valveis used to prevent the air G from entering the airbagfrom the air inlet′. The components in this embodiment share the same identifiers as those in the previous embodiments and have the same structure; therefore, I won't elaborate on them further for the sake of brevity.

Please refer to, which illustrates an express delivery bagand its structural configuration′ in the eighth embodiment of the present invention. The main difference between express delivery bagand its structural configuration′ and the previously described express delivery bagand its structural configuration′ lies in the fact that the airbag film layer′ of express delivery bagand its structural configuration′ additionally has a film layer perforation line. The film layer perforation linepenetrates the airbag film layer′ and is located adjacent to one of the edge-sealing structures, connecting the third top edgewith the fourth top edge.

When the airbag film layer′ transitions from the flat state to the inflated state, the thickness of each airbagincreases due to inflation, causing a reduction in the width of each airbag. In practice, the width of each airbagin the inflated state decreases by approximately 10%-30% compared to the width in the flat state.

Furthermore, since the airbag film layer′ and the plastic bag film layerare fixedly joined by the edge-sealing structure, when the width of the airbagdecreases due to inflation while the plastic bag film layerremains unchanged, the reduction in the width of the airbagcauses the airbag film layer′ to pull the plastic bag film layerinward. As mentioned above, the film layer perforation linecreates a weaker structural point in the airbag film layer′ at the location of the film layer perforation line. Therefore, when the width of the airbagdecreases, causing the airbag film layer′ to pull the plastic bag film layerinward, the airbag film layer′ may detach from the plastic bag film layerat the location of the film layer perforation lineeither by self-separation or by external force pulling. In this way, after the separation between the plastic bag film layerand the airbag film layer′, the plastic bag film layercan remain unchanged in appearance (e.g., without wrinkles) despite being pulled, thus maintaining the appearance of the express delivery bagand its structural configuration′. Components in this embodiment share the same labels as in the previous embodiments and possess identical structures, and for brevity, these are not reiterated here.

Please refer to, which illustrates an embodiment of the present invention, an express delivery bagand its structural configuration′. The main difference between express delivery bagand its structural configuration′ and the previously described express delivery bagand its structural configuration′ lies in the fact that the containing space of the inner bag formed by the airbag film layeris used to accommodate an object O (e.g., a book, a parcel), and an identity authentication component F is attached to object O. Consequently, when object O is placed inside the containing space of the inner bag, the identity authentication component F, along with object O, is placed inside the inner bag, enabling the express delivery bagand its structural configuration′ to be identified, tracked, and statistically analyzed during the logistics process. Alternatively, the identity authentication component F can also provide anti-theft functionality. For example, when an express delivery bagand its structural configuration′ with an identity authentication component F that has not been deactivated passes through a reader, the reader may issue a warning, thereby achieving anti-theft functionality. Additionally, because the identity authentication component F assigns an identity to the express delivery bagand its structural configuration′, it is possible to predefine in the management system whether the identified identity is allowed to pass or not. Consequently, when an express delivery bagand its structural configuration′ with an identity authentication component F that has been permitted to pass through the reader, the management system, upon reading the returned identity, determines that the identity is allowed to pass, and thus the reader does not issue a warning. Conversely, when an express delivery bagand its structural configuration′ with an identity authentication component F that has not been permitted to pass through the reader, the management system, upon reading the returned identity, determines that the identity is not allowed to pass, and thus the reader issues a warning, thereby achieving anti-theft functionality.

As shown in, the plastic bag film layerhas a first surfacefacing the airbag film layer, and the first surfacehas a first binding region. The airbag film layerhas a second surfaceA facing the plastic bag film layer, and the second surfaceA has a second binding regionA. An area of the first binding regionis smaller than the area of the first surfaceof the plastic bag film layer, and an area of the second binding regionAis smaller than the area of the second surfaceA of the airbag film layer. Additionally, the first binding regionand the second binding regionAcan be adhered to each other by an adhesive.

Please refer to, which illustrates an embodiment of the express delivery bagand its structural configuration′. The main difference between the express delivery bagand its structure′ compared to the previously described express delivery bagand its structure′ lies in the inclusion of an identity authentication component F. The identity authentication component F is positioned on either the airbag film layeror the plastic bag film layer. In this embodiment, the identity authentication component F is positioned on the outer side of the plastic bag film layer(i.e., the outer bag), but the invention is not limited to this configuration. For example, the identity authentication component F could also be positioned on the inner side of the plastic bag film layer(i.e., the outer bag) opposite to the outer side, or on the outer side of the airbag film layer(i.e., the inner bag), or on the inner side of the airbag film layeropposite to the outer side, depending on the specific requirements.

In practice, the identity authentication component F can be a wireless radio frequency tag, a two-dimensional code (QR code), or a one-dimensional code (bar code). The identity authentication component F can be attached to the airbag film layeror the plastic bag film layer, or placed inside the inner bag containing space, or positioned between the airbag film layerand the plastic bag film layer, for example, within the space between them. In this way, the identity authentication component F can provide identity information, enabling the express delivery bagand its structural configuration′ to be identified, tracked, and accounted for during the logistics process. Additionally, the identity authentication component F can serve an anti-theft function. For instance, when an express delivery bagand its structural configuration′ containing an identity authentication component F with active identification features pass through a reader, the reader can issue a warning, thereby serving an anti-theft function. Alternatively, because the identity authentication component F assigns a unique identity to the express delivery bagand its structural configuration′, the management system can preset the allowed or disallowed status based on this identity. Consequently, when an express delivery bagand its structural configuration′ with an identity authentication component F that allows passage pass through a reader, the management system, upon reading the returned identity, determines the identity as permitted, and thus, the reader does not issue a warning. Conversely, when an express delivery bagand its structural configuration′ lacking an identity authentication component F that allows passage pass through a reader, the management system, upon reading the returned identity, determines the identity as not permitted, and thus, the reader issues a warning, thereby serving an anti-theft function.

Please refer to. It illustrates an express delivery bagand its structural configuration′, representing the eleventh embodiment of the present invention. Unlike the previous embodiments, based on practical usage requirements, object O can optionally be accommodated between the outer bag and the inner bag. In this case, when object O is accommodated between the outer bag and the inner bag, the identity authentication component F, along with object O, is placed between the outer bag and the inner bag, enabling the express delivery bagand its structural configuration′ to be identified, tracked, and accounted for during the logistics process. Alternatively, the identity authentication component F can also serve an anti-theft function. For instance, when an express delivery bagand its structural configuration′ containing an identity authentication component F with active identification features pass through a reader, the reader can issue a warning, thereby serving an anti-theft function. Or, because the identity authentication component F assigns a unique identity to the express delivery bagand its structural configuration′, the management system can preset the allowed or disallowed status based on this identity. Consequently, when an express delivery bagand its structural configuration′ with an identity authentication component F that allows passage pass through a reader, the management system, upon reading the returned identity, determines the identity as permitted, and thus, the reader does not issue a warning. Conversely, when an express delivery bagand its structural configuration′ lacking an identity authentication component F that allows passage pass through a reader, the management system, upon reading the returned identity, determines the identity as not permitted, and thus, the reader issues a warning, thereby serving an anti-theft function.

Compared to previous technologies, the airbag film layer compartments of the express delivery bag and structural configuration of the present invention can change from the flat state to the inflated state after inflation. Therefore, during transportation, it is possible to keep the compartments uninflated, maintaining the express delivery bag and structural configuration in the flat state, thereby reducing the volume of the express delivery bag and structural configuration during transport and lowering transportation costs. When it is desired to package items using the express delivery bag or structural configuration of the present invention, the compartments can then be inflated to transition the express delivery bag and structural configuration to the inflated state, providing cushioning and protection. Additionally, the express delivery bag and structural configuration of the present invention feature an identity authentication component. This identity authentication component can provide identity information, enabling the express delivery bag and its structure to be identified, tracked, and accounted for during the logistics process, or it can serve an anti-theft function.

It should be realized that the above description is only some preferred embodiments of the present invention and should not be deemed as limitations of implementing the present invention. All substantially equivalent variations and modifications which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present invention.
