Vacuum suction type gas packing bag and packing method thereof

Abstract

The invention provides a vacuum suction gas package and a packaging method thereof. The vacuum suction gas package comprises a gas column plate provided with a gas-filling channel and an accommodating space, wherein the gas column plate comprises two outer membranes and two inner membranes which are arranged between the two outer membranes; a strip of heat-resistant materials is at least coated into the two inner membranes; the two outer membranes and the two inner membranes are adhered to each other through heal seals; at least one gas inlet is formed on the heat-resistant materials and between the two inner membranes and makes gas flow into the inside of the gas column plate from the gas-filling channel; the gas column plate is folded to form a first buffer wall and a second buffer wall which are communicated with each other; and two side edges of the first buffer wall and the second buffer wall are adhered to each other through heat seals, so as to form the accommodating space which is used for accommodating articles. When a gas column is inflated and expanded and the inside of the accommodating space is vacuumized, the first buffer wall and the second buffer wall tie up the articles, and make the articles fixed into the accommodating space, incapable of swinging along with the gas package and incapable of pricking the gas package as well.

Description

technical field [0001] The invention relates to a gas packaging bag and a packaging method thereof, in particular to a vacuum suction beam type gas packaging bag and a packaging method thereof. Background technique [0002] Generally, when packing items, the items will be placed directly into the carton, but because the carton can only pack the items and has no cushioning protection function, the items are easily damaged due to shaking during transportation, so cushioning materials are often placed in the carton during packaging In order to improve the buffer protection function of the carton. A common method is to stuff foam between the article and the carton, and use the softness of the foam to provide cushioning and protection for the article. However, the foam is expensive, which increases the packaging cost and does not meet the economic effect, and the foam is not easy to handle after use, which is easy to cause environmental problems. Furthermore, although the foam ...

Problems solved by technology

If there is a small hole in the gas packaging bag, the gas in the gas packaging bag will leak out, causing the gas packaging bag to lose the function of cushioning and protection, thereby increasing the packaging cost of the item

In order to solve this problem, the plastic film of the gas packaging bag can be strengthened or thickened to reduce the chance of being punctured by objects, but in the continuous mass production mode, it is impossible to strengthen or thicken a single side of the gas packaging bag. It is ne
