Gas packing bag with multistage gas column

Abstract

A multi sectional air post air bag is made of several air post and separated by heat sealing line. The No.1 air post comprises several No.1 air post section with relatively bigger estimated width, complex number No.2 air post section with relatively smaller estimated width, and the linking channel between the No.1 air post section and No.2 air post section. The No.1 air post section estimated width is bigger than the No.2 air post estimated width, with linking channel estimated width far less than No.1 and No.2 air post sections. In compact, the No.1 air post section taking the impact load, with the No.2 air post bearing it at the same time. It uses several No.1 air post and No.2 air post with air packing bag absorbing the impact load one layer after another, to protect the container. It sets various air post section inside one air post, greatly increasing the shock proof ability of the air packing bag.

Description

technical field [0001] The present invention relates to a packaging bag, in particular to a gas packaging bag with a multi-section air column, which is formed by connecting a plurality of air columns, and each air column includes a plurality of first air column sections with a larger predetermined width, A plurality of second air column sections with a smaller predetermined width, and a connecting channel connected between the first air column section and the second air column section, etc., when subjected to an impact load, the first air column section first The impact load is borne, and then the second air column section bears it, so that the gas packaging bag can absorb the impact load layer by layer, so as to greatly improve the shock resistance of the gas packaging bag. Background technique [0002] The traditional method for cushioning and packaging items is to protrude from a plastic sheet with a plurality of raised small air bubbles, and wrap the plastic film on the ...

AI Technical Summary

Problems solved by technology

When subjected to a large impact load, each gas column bag is often broken at the same time, making it unable to withstand a large impact load, and also has the disadvantage that the scope of use cannot be promoted.
