摘　　要：主要介绍了聚乳酸(PLA)的制备、改性以及在包装领域中的应用。指出通过改变PLA立构规整度、与其它单体共聚或与高分子、有机和无机增韧增强剂共混等方法可以很大程度上改善PLA的韧性、耐穿刺性能和耐热性等性能,制备出满足包装应用性能的材料。并且,PLA优异的生物可降解性能和生物可再生性,在很大程度上缓解了资源和环境的压力,是一种发展前景广泛的包装材料。As a type of new packing materials,the preparation,modification and application in packing of polylactic acid(PLA)were reviewed.It was pointed out that the ductility,puncture resistance and heat resistance properties of PLA could be improved by improving the isotacticity of PLA,copolymerization with other monomers and blending with polymeric,organic or inorganic assistant.Moreover,the excellent biodegradability and biological renewability of PLA effectively relieve the pressure of resources and environment.PLA is promising packaging material.
