PLA/PBAT复合膜制备技术及其在食品包装中的应用前景
Study on Preparation Technology and Application Prospects of PLA/PBAT Composite Film in Food Packaging
摘要
Abstract
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.关键词
