With the increasing living standards of the public, various types of leisure food are increasingly popular and the demand is also increasing. As is well known, the selection and production requirements of food packaging bags are different from ordinary packaging bags.

Specifically, the production requirements for food packaging bags should meet the following points: firstly, food packaging bags should be able to protect the packaged food, thus requiring high barrier properties, such as water vapor, gas, oil, and organic solvents; Secondly, according to the specific packaging requirements of the food, certain conditions should be met, such as rust prevention, static electricity prevention, electromagnetic radiation prevention, etc; Furthermore, food packaging bags must protect the safety of packaged food from external factors, prevent contamination, and extend the shelf life of the food.

In terms of material selection, the main and auxiliary materials used in food packaging bags must not contain substances that are harmful to the human body, or the content should be within the allowable range of national standards.

Due to the unique nature of food grade packaging materials, only by strictly following production standards can the food packaging bag products produced be approved and put into the market.

All inner packaging bags that come into direct contact with food strictly adhere to the production process of food grade packaging bags, which not only ensure safety and hygiene, but also ensure the original taste of delicious food; Instead of food grade packaging bags, the main difference in material composition lies in the use of additives. If opening agents are added to the materials, they cannot be used for food packaging.

Food packaging bags are widely used in the market, and according to their different application ranges, we commonly find food packaging bags in the market, including ordinary food packaging bags, vacuum food packaging bags, inflatable food packaging bags, boiled food packaging bags, steamed food packaging bags, and functional food packaging bags.
