Gas packaging bag capable of retracting and buffering automatically

Abstract

The invention provides a gas packaging bag capable of retracting and buffering automatically. The gas packaging bag capable of retracting and buffering automatically is formed by connecting two external films in a hot sealing mode. The gas packaging bag capable of retracting and buffering automatically comprises a first air column piece, a second air column piece, a third air column piece, and a plurality of retracting area blocks, wherein the first air column piece comprises a plurality of first air columns, the second air column piece is communicated with the first air column piece and comprises a plurality of second air columns, the third air column piece is communicated with the second air column piece and comprises a plurality of third air columns, the plurality of retracting area blocks are located at one ends of the third air columns and used for retracting the third air columns, and the third air column piece and the second air column piece are bent towards the first air column piece, so that the third air column piece and the first air column piece are slightly perpendicular to the second air column piece to clamp an object. The gas packaging bag capable of retracting and buffering automatically can automatically retract and shrink to match and adapt to to-be-packaged objects of different dimensions.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a gas packaging bag capable of automatic retraction and cushioning. Background technique [0002] At present, when packaging items, most of them use bubble wrap or Styrofoam to wrap the items, but there are still problems such as poor cushioning effect and easy damage to the items. In order to solve the shortcomings of the poor cushioning effect of the prior art, a gas packaging bag made of resin film has been developed, which is heat-sealed into a sealed state to form an air column, and is provided with an inflatable Inflatable port, when the gas is filled into the air column through the inflatable port, the gas packaging bag can be used as a cushioning material in the inner packaging. [0003] The gas packaging bag uses a one-way air stop valve to make multiple inflated air columns, preset turning nodes on the air columns, and seal the turning edges of the air column sh...
