It can withstand high temperature and high pressure treatment, and can also be processed into various shapes and sizes to meet the packaging requirements of different foods. Food packaging foil has good moisture resistance. It can effectively prevent moisture from entering the package, thus maintaining the moisture content of the food and preventing it from becoming soft or hard. Food packaging foil has good sealing performance. It can be heat-sealed or cold-sealed to ensure that the package is airtight and leak-free, thus maintaining the freshness and taste of the food for a long time. Food packaging foil is a high-performance packaging material that plays an important role in food packaging and preservation.
