Meanwhile, when the packaging gas column bag is strongly extruded, the gas in the large inflation cavity is inflated into the small inflation cavity to prevent the gas column bag from bursting.

Furthermore, the round small inflation cavity is nested inside the large inflation cavity, and the small inflation cavities of the two specifications are nested to form a three-dimensional working condition, so that the fixation and protection of the contents are facilitated.

Furthermore, the air column bag of the array structure is provided with one or more point sealing folding lines in the air column bag body, the air column bag can be folded to form an upper cushion pad and a lower cushion pad after being inflated, and a plurality of array-type cavities formed by the upper cushion pad and the lower cushion pad realize the comprehensive fixation and protection of the contents.

Furthermore, two sides of the gas column bag of the array structure are provided with self-sealing strips, and the self-sealing strips are used for fixing the upper cushion pad and the lower cushion pad.

Compared with the prior art, the beneficial effects are:

this patent is through setting up special-shaped big inflation chamber and the circular little inflation chamber of complex to carry out reasonable layout to it, can fix and protect a plurality of egg products or the product of similar shape. The utility model discloses an arc dysmorphism structure can prevent gaseous adverse current for its gaseous more difficult the revealing than general cylindrical gas column, can guarantee the article security of long distance, long-time commodity circulation transportation. The big inflation cavity and the small inflation cavity are communicated through the micropores, egg articles can be better attached, fixed and buffered, and extrusion damage is prevented. The utility model discloses the adventitia chooses for use the film material that intensity is higher, makes this gas column bag have higher intensity, and the inner membrance chooses for use the material that the better thickness of elasticity is thinner, makes it the laminating protection article that can be better when receiving the extrusion.

The utility model discloses simple structure, low in cost can effectual improvement in the transportation to the protection of eggs.
