一、降解薄膜的应用为了延长塑料的使用期限，防止塑料制品在使用过程中由于光、热、氧气、机械力的作用而发生降解反应，从而降低其机械物理性能，缩短塑料制品的可使用年限，因而在塑料中添加了各种抗氧剂、热稳定剂。降解塑料恰好相反，为了加快塑料的降解分解，在塑料中添 First, the application of biodegradable film In order to extend the use of plastic period, to prevent plastic products in the course of the use of light, heat, oxygen, mechanical degradation of the reaction occurred, thereby reducing its mechanical and physical properties and shorten the useful life of plastic products , So in the plastic added a variety of antioxidants, heat stabilizers. Degradation of plastic on the contrary, in order to speed up the decomposition of plastic degradation, in the plastic Tim
