英文摘要:

      Soft plastic films are suitable for a variety of packaging. The mechanical performances of food packaging materials are the most basic performance which can protect the packaging from damage and leakage. This paper expounded the main mechanical properties of food packaging plastic films, such as tensile property, peel strength, sealing strength, tear property, impact resistance and puncture performance, and summarized the main test methods of mechanical properties of the food packaging plastic films, so as to provide references for the research of food packaging technology and the development of new products.
