完全生物降解CPP薄膜的研制

介绍了CPP薄膜添加完全生物降解材料改性的研究。分析对比了添加不同比例完全生物降解材料的CPP薄膜降解效果。结果表明:添加完全生物降解材料的CPP薄膜在一年保质期内保持了良好的物理力学性能,且其在自然环境下降解效果优于未降解改性的CPP包装薄膜;通过添加适当比例的完全生物降解材料,可实现降解的可控性。

Preparation of completely biodegraded CPP Film

It studies the application of completely biodegraded materials in CPP film. The degradation effects of CPP film with different ratio of completely biode graded materials are compared with experimental analysis. Results show that com pletely biodegraded modified CPP film not only retains good physical and mechani cal properties in one year shelf life, also the degradation effect better than unmodi fied CPP film in the natural environment. It can realize the controllable degrada tion by adding an appropriate proportion of the comDletelv biodearaded material.
