摘　　要：随着生态环境问题日益严峻,常规包装材料是造成“白色污染”的主要来源物。为了生态的可持续发展,可生物降解的绿色环保材料成为了我们主要关注和发展的对象。聚乳酸(PLA)是以良好生物降解性能、光学性能和易于加工性,成为了市场上目前最有潜力的绿色环保材料。本文概述了聚乳酸(PLA)的增韧、增透、阻隔、生物降解等方面的研究,并对聚乳酸(PLA)在食品保鲜、农用地膜中的应用进行了综述。With the increasingly severe ecological environment problems,conventional packaging materials are the main source of"white pollution".For the sustainable development of ecology,biodegradable green materials have become our main concern and development object.Polylactic acid(PLA)has become the most potential green material in the market due to its good biodegradability,optical properties and easy processing.In this paper,the research on toughening,anti-reflection,blocking and biodegradation of polylactic acid(PLA)was summarized,and the application of PLA in food preservation and agricultural mulching film was reviewed.
