Food packaging bags also have a variety of materials: PE bags, aluminum foil bags, composite bags, nylon bags are more common.

Vacuum bag is to extract and seal all the air in the package, so as to maintain the bag in a highly decompressed state. The lack of air is equivalent to the effect of low oxygen, so that the microorganisms do not have living conditions, so as to achieve the purpose of fresh food and free from disease and rot.

Food aluminum foil bag is made of aluminum and other high barrier materials according to the unique nature of aluminum after dry composite into aluminum foil bag products. Aluminum foil bag has good functions of moisture resistance, barrier, light resistance, permeability resistance and beautiful appearance.

Food grade packaging must meet all aspects of food protection needs:

2. According to the special requirements of actual production, add functions such as rust prevention, corrosion prevention and electromagnetic radiation prevention;

3, to ensure food safety and pollution-free and extend the shelf life of food.

The main and auxiliary materials used in food-grade packaging shall not contain any harmful substances to human body, or the content shall be within the limits allowed by the national standards.
