Description

Gas packaging bag capable of automatic feeding and cushioning

technical field

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

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 package.

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 sheets into a cushioning air bag that can accommodate items, providing more cushioning materials. Excellent cushioning packaging structure.

However, the gas packaging bags on the market must be customized according to the size of the packaged items, which is very inconvenient and time-consuming. If a general size is used, some small parts must be stretched or shrunk, which also causes inconvenience in use. .
