What are the food packaging film materials?

The food packaging film has the characteristics of light weight, convenient use, good heat resistance and cold resistance, and has a good-looking appearance. It can directly contact with food without leaving any residue to ensure the food is fresh, hygienic and safe. Today, I will introduce the materials of food packaging film: 1. Polycyano fatty acid ester: It is a kind of high biological material, with degradability and thermal processing properties, and can keep food fresh for a long time. 2. Polyethylene: stable chemical properties, good water blocking performance, tensile strength and low temperature resistance. 3. Polypropylene: as a film material for packaging food, suitable for fried food packaging. 4. Polyvinyl chloride: used for fresh fruit packaging, it has poor thermal stability, but good gas and oil resistance. 5. Polycarbonate: It can be injection molded into basins and boxes, with good transparency and impact resistance, but the price is higher. The food packaging film sold by our company can provide exquisite printing effects and composite materials with different functions.
