　　The vacuum packaging bag will be automatically sealed after vacuum treatment. Because the vacuum inside the bag is high and there is less gas residue, it can inhibit the growth of bacteria and other microbial strains, especially for food packaging. Therefore, the packaging can realize the characteristics of "four prevention, two saving and one quality guarantee": water content, Aspergillus flavus, environmental pollution, air oxidation, volume saving, transportation cost saving and storage period extension. Vacuum packaging bags are suitable for various plastic composite film bags or aluminum foil bags, such as polyester/polyethylene, nylon/polyethylene, polypropylene/polyethylene, polyester/aluminum foil/polyethylene, nylon/aluminum foil/polyethylene and other composite materials, and for all kinds of solid, powdery objects, liquids The solid liquid mixture is vacuum packed. In food enterprises, plastic packaging bags are very common in food, such as chicken wings, sausages, sausages, etc. Vacuum packaging bag is an indispensable food packaging bag in people's daily life, so what are the benefits that people cannot keep it?

It is necessary to prevent the food from being extruded by machinery or external forces, and this kind of food is easy to be damped and oxidized. When packaging, relay and packer cooperate with each other. Before cross sealing, timely enter the packer bag for air injection. The volume of steam and length of gas can be adjusted. Excessive inflation will displace the packaging bag, resulting in the fixture; Too little inflation is difficult to achieve the effect of food protection. Therefore, it is necessary to carefully debug the packaging equipment.

　　The above is a description of the characteristics of food vacuum packaging bags. In general, plastic food vacuum packaging bags provide better protection for people's production convenience and health.
