Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 2, a collapsible composite packaging bag comprises a bag body 1 and extrusion blocks 4, wherein limiting frames 2 are arranged on two sides in the bag body 1, a strip-shaped air bag 3 for collapsing a bag opening is connected to one side in each limiting frame 2 through gluing, the extrusion blocks 4 for inflating are connected to one side of the bag body 1 through gluing, and one end of each extrusion block 4 is connected with the strip-shaped air bag 3.

The bag body 1 comprises a polyester fiber layer 7, a cow leather layer 8 is arranged on the outer surface of the polyester fiber layer 7, an anti-slip layer 9 is arranged on the outer surface of the cow leather layer 8, and a woven fabric layer 10 is arranged between the cow leather layer 8 and the anti-slip layer 9.

In this embodiment, as shown in fig. 4, the anti-slip layer 9 is a frosted material layer, and the woven material layer 10 is made of expanded polytetrafluoroethylene, so that the use strength and comfort of the packaging bag 1 are greatly improved.
