As shown in fig. 1-5, the utility model provides an air-filled packing bag, including a plurality of gasbag 10 that communicate each other, each gasbag 10 passes through connecting portion 30 interconnect, and at least a part of gasbag 10 is made by flexible pressure-bearing material 20, and pressure-bearing material 20 includes plastic film layer 21, weaving layer 22 and kraft paper layer 23 that set gradually from inside to outside. The flexible backing material 20 is capable of deforming upon inflation into the bladder 10, thereby allowing the bladder 10 to expand.

The plastic film layer 21 of the flexible pressure-bearing material 20 is mainly used for sealing gas, so that the gas is prevented from leaking through the flexible pressure-bearing material 20, and the plastic film layer 21 is arranged on the inner side, so that the plastic film layer 21 is not easy to damage. The plastic film layer 21 may be, but is not limited to, a monolayer film or a coextruded film. The braided layer 22 is mainly used for improving the mechanical property of the flexible pressure-bearing material 20, and the pressure-bearing capacity of the air bag 10 can be greatly improved by utilizing the criss-cross warps and wefts of the braided layer 22. Braided layer 22 may be, but is not limited to, a woven plastic cloth. The kraft paper of the kraft paper layer 23 has excellent mechanical properties by itself, and the combination thereof with the woven layer 22 can impart excellent pressure-bearing capacity to the air packing bag.

In some embodiments, one airbag 10 of the inflatable packaging bag has an inflation port 101, and a valve 102 is disposed at the inflation port 101, and the valve 102 is used for opening or sealing the inflation port 101. When the valve 102 is opened, the air bags 10 can be inflated through the inflation port 101, and at the same time, since the air bags 10 are communicated with each other, the air bags 10 are inflated, so that the air can be ensured to enter the air bags 10. When the inflation is complete, the valve 102 is closed and gas cannot leak through the inflation port 101. After the use of the inflatable packaging bag is finished, the valve 102 can be opened to discharge the gas in each air bag 10 from the inflating opening 101, so that the inflatable packaging bag can be recycled, and the inflatable packaging bag can be inflated again when being reused next time.

In other embodiments, inflation ports and valves may be provided on a plurality of air bags 10 of the inflatable packaging bag, and when the inflatable packaging bag is inflated, the inflation ports are inflated simultaneously, so as to improve the inflation efficiency.

Of course, in other embodiments, the inflation port and valve may not be provided, and the airbag 10 may be sealed after the airbag 10 is inflated for the first time.

In some embodiments, the respective air bags 10 are arranged in sequence to form a row, that is, a plurality of connecting portions 30 extend parallel to each other from one side of the air bag to the other side of the air bag, as shown in fig. 4.

In other embodiments, the respective air bags 10 are arranged in an array to form at least two rows and at least two columns, that is, the air bag has a plurality of transverse connecting portions 31 and a plurality of longitudinal connecting portions 32, the transverse connecting portions 31 extend from the left side of the air bag to the right side of the air bag in parallel with each other, and the longitudinal connecting portions 32 extend from the upper side of the air bag to the lower side of the air bag in parallel with each other, as shown in fig. 5.

When one airbag 10 is adjacent to a plurality of airbags 10, the airbag 10 may be communicated with only one adjacent airbag 10, or may be communicated with all of the plurality of adjacent airbags 10, and it is only necessary to ensure that each airbag 10 is communicated with the airbag 10 provided with the inflation port 101.

Preferably, the air bag 10 communicates with all the adjacent air bags 10, thereby contributing to an improvement in inflation efficiency.

The intercommunication of the airbags 10 can be achieved in various ways, for example: hoses can be provided between the respective air bags 10 to allow the respective air bags 10 to communicate with each other, but the structure is relatively complicated and is easily damaged. In a preferred embodiment, the connecting portion 30 connecting the two airbags 10 has a gas passage 301 for communicating the airbags 10 at both sides, so that the adjacent airbags 10 communicate through the gas passage 301 at the connecting portion 30.

In some embodiments, the connection between the air bags 10 and the air bags 10 is flexible, that is, the angle between adjacent air bags 10 can be changed, and in practical use, the angle between each air bag 10 can be adjusted according to the shape of the packaged object, so that each air bag 10 is contacted with the surface of the object as much as possible, as shown in fig. 6. When the respective air bags 10 are arranged in a row in sequence, as shown in fig. 4, the inflatable packing bag may be bent in a cylindrical shape; when the air bags 10 are arranged in an array of a plurality of rows and a plurality of columns, as shown in fig. 5, the air bag can be bent in the transverse direction to form a cylindrical shape, or in the longitudinal direction to form a cylindrical shape, and the transverse dimension and the longitudinal dimension of the air bag are set to two different dimensions, so that the air bag can be simultaneously suitable for packaging two different sizes of articles.

Further, the inflatable packaging bag comprises an upper packaging layer 11 and a lower packaging layer 12, at least one of the upper packaging layer 11 and the lower packaging layer 12 is made of a flexible pressure-bearing material 20, the peripheral edges of the upper packaging layer 11 and the lower packaging layer 12 are connected in a sealing mode to achieve the overall sealing of the inflatable packaging bag, the upper packaging layer 11 and the lower packaging layer 12 are further connected in multiple positions within the peripheral edges to form a plurality of connecting portions 30, each connecting portion 30 divides the inflatable packaging bag into a plurality of air bags 10, each connecting portion 30 is provided with at least one air passage 301, so that the air bags 10 on two sides of each connecting portion 30 are communicated, namely the upper packaging layer 11 and the lower packaging layer 12 are not connected at the air passages 301.

It will be understood by those skilled in the art that the upper wrapper layer 11 and the lower wrapper layer 12 may be two layers formed by folding a continuous material, or may be two layers independent of each other.

The formation of the connecting portion 30 can be achieved by various ways, for example, directly connecting the upper packaging layer 11 and the lower packaging layer 12 by sewing, forming the connecting portion 30 at the sewing position, and forming the gas channel 301 by the sewn gap; for another example, the upper casing layer 11 and the lower casing layer 12 are bonded together with glue, the joint portion 30 is formed at the bonded portion, and the glue is provided at intervals, thereby forming the gas passage 301.

In the embodiment shown in fig. 1, the material of the upper and lower packaging layers 11 and 12 is a flexible pressure-bearing material 20, that is, the material of each airbag 10 is a flexible pressure-bearing material 20. Meanwhile, the connection between the air bags 10 is flexible, and the inflatable packaging bag can be bent.

In the embodiment shown in fig. 2, the material of the upper packaging layer 11 is a flexible pressure-bearing material 20, the material of the lower packaging layer 12 is a hard material 40, one part of each air bag 10 is the flexible pressure-bearing material 20, and the other part is the hard material 40, wherein the surface area of the flexible pressure-bearing material 20 is larger than that of the hard material 40, so that when the air bag 10 is inflated, the flexible pressure-bearing material 20 extends to expand the air bag 10. In other words, each airbag 10 has a surface area of the upper wrapper 11 that is larger than a surface area of the corresponding lower wrapper 12, so that when the airbag 10 is inflated, the upper wrapper 11 is stretched to inflate the airbag 10. Meanwhile, the connection between the air bags 10 is rigid, and the air bag is not easy to bend.

The hard material 40 may be, but is not limited to, cardboard.

In the embodiment shown in fig. 4, the plurality of connecting portions 30 extend parallel to each other from one side of the air packing bag to the other side of the air packing bag.
