食品包装塑料薄膜的机械性能及检测方法研究

Mechanical properties and test methods of food packaging plastic film

柔软的塑料薄膜适用于各种各样的包装,食品包装材料的机械性能是产品在包装之后对产品进行保护的最基本性能,可以防止包装的破损与泄漏。本文阐述了食品包装塑料薄膜的主要机械性能,包括拉伸性能、剥离性能、热合性能、撕裂性能、冲击性能以及穿刺性能,并介绍了主要的食品包装塑料薄膜的机械性能检测方法,为食品包装技术的研究和新产品的开发提供参考。

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.
