Gas packing bag for compactly holding articles and manufacturing method thereof

Abstract

The invention provides a gas package for closely clamping articles and a manufacturing method thereof. The gas package comprises a first outer membrane and a second outer membrane which are overlapped up and down, wherein the first outer membrane comprises a first side edge, a second side edge and a folding edge which is positioned between the two side edges; the first outer membrane and the second outer membrane are folded along the folding edge, and the second outer membrane is overlapped on the outside of the first outer membrane; the first outer membrane and the second outer membrane after folding are adhered to the folding edge through a heat seal to form a heat-sealing part; the first outer membrane and the second outer membrane are adhered to each other through the heat seal; at least one first air chamber is formed between the first side edge and the heat-sealing part; at least one second air chamber is formed between the second side edge and the heat-sealing part; an accommodating space for storing the articles is formed inside the first outer membrane; the folded first outer membrane is provided with at least one ventilation hole; and the first air chamber and the second air chamber are communicated with each other through the ventilation hole which is close to the folding edge. When the air chambers are inflated and expanded, the first air chamber and the second air chamber can tie up the articles and make the articles fixed into the accommodating space. The structure strengthens the buffer protection function on the articles and can also prevent the articles from pricking the gas package.

Description

technical field [0001] The invention relates to a gas packing bag and a manufacturing method thereof, in particular to a gas packing bag tightly clamping articles and a manufacturing 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 without the buffer protection function, the items are easily damaged due to shaking during transportation, so the buffer is often placed in the carton when packing the items material to improve the cushioning 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 protection for the article. However, the cost of foam is expensive, which will increase the cost of packaging and is very uneconomical, and the waste of foam is not easy to dispose of, which is likely to cause environmental problems. Furthermore, although the f...

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 effect 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, thereby reducing the chance of being punctured by objects, but under continuous mass production conditions, it is impossible to strengthen or thicken a single side of the
