Study on Preparation Technology and Application Prospects of PLA/PBAT Composite Film in Food Packaging
聚乳酸(PLA)作为可再生可降解的环境友好型新材料,具有极大的环境和经济价值,但其脆性较大成为限制其发展的主要原因,为解决聚乳酸(PLA)韧性差这一问题,将 PLA与聚己二酸对苯二甲酸丁二酯(PBAT)共混可显著增强其韧性.PLA/PBAT复合膜作为一种生物可降解材料,因其具有原料丰富、成本低廉和环境友好等优点被广泛应用.该文概述了PLA/PBAT复合膜的不同制备方法及工艺研究现状.总结了复合膜的改性技术包括无机填料、扩链增容、交联剂改性、淀粉改性和协同改性等.最后介绍了PLA/PBAT复合膜在食品包装中的潜在应用及发展前景,以期为PLA/PBAT复合膜在未来食品包装中的研究提供理论参考和新思路.
Polylactic acid(PLA)is a biodegradable and bio-based aliphatic polyester.It has received extensive attention due to its great environmental and economic value.As a biodegradable material,Polylactic acid(PLA)has poor impact toughness,resulting in a limitation of application.Blending PLA with polybutylene adipate terephthalate(PBAT)can significantly enhance its toughness.PLA/PBAT composite films,as a biodegradable material,is widely used due to its advantages of abundant raw materials,low cost,and environmental friendliness.This article outlines the different preparation methods and current research status of PLA/PBAT composite membranes.The modification technologies of composite membranes,including inorganic fillers,chain expansion and compatibilization,crosslinking agent modification,starch modification,and synergistic modification are summarized.Finally,the application and development prospect of PLA/PBAT composite films in food packaging is introduced,which provide theoretical references and new ideas for future research on PLA/PBAT films in food packaging.
