Abstract:

This paper introduced the performance characteristics of polymer materials commonly used in food packaging as well as the new processing methods and packaging materials. The biaxially oriented polyethylene, casting polyethylene, polypropylene films, biaxially oriented polyamide films obtained prepared by the LISIM method, and polyester films were discussed. The research status of multilayer composite packaging materials was reviewed. The development trend of food packaging technologies in future was prospected. It can be speculated that packaging materials will be developed to a high-barrier, lightweight, and environment-friendly direction. The preparation of high-performance packaging materials can be realized by using composite and advanced processing technologies.

Key words: food packaging, polymer material, high-barrier, lightweight, easy recycl
