At the same time, when the packaging air column bag is strongly squeezed, the gas in the large inflatable cavity is filled into the small inflatable cavity to prevent the air column bag from bursting.

Further, the circular small inflatable cavity is nested inside the large inflatable cavity, and the three-dimensional working condition formed by the nesting of the small inflatable cavity of two specifications is convenient to realize the fixation and protection of the contents.

Further, the air column bag of the array structure has one or more point sealing and folding lines in the air column bag body, and the air column bag can be folded to form an upper buffer pad and a lower buffer pad after being inflated, and multiple arrays formed by the upper and lower buffer pads. The type of cavity can realize the comprehensive fixation and protection of the contents.

Further, self-sealing strips are provided on both sides of the air column bag of the array structure, and the self-sealing strips can fix the upper and lower buffer pads.

Compared with the prior art, the beneficial effects are:

This patent can fix and protect multiple egg products or products of similar shape by setting a special-shaped large air cavity and a matching circular small air cavity, and rationally distributing them. The arc-shaped special-shaped structure adopted by the utility model can prevent the gas from flowing backwards, so that the gas is less likely to leak than the general cylindrical gas column, and can ensure the safety of items for long-distance and long-term logistics transportation. The large inflatable cavity and the small inflatable cavity are communicated through micropores, which can better fit, fix, buffer and protect egg items and prevent extrusion damage. The outer film of the utility model adopts a film material with higher strength, so that the air column bag has higher strength, and the inner film adopts a material with better elasticity and thinner thickness, so that it can better fit and protect when it is squeezed. thing.

The utility model has the advantages of simple structure and low cost, and can effectively improve the protection of eggs during transportation.
