摘要
本文介绍了聚乳酸的研究历史、性质及生产应用,总结了针对PLA加工性能差、韧性低、耐热性不佳、脆性高等缺陷的物理改性方法,并对近几年来PLA材料在食品包装中的应用做了说明,最后展望了PLA生物可降解材料的前景与发展。
This article introduces the research history, properties and application of Poly(lactic acid )(PLA), summarizes the physical modification methods for PLA's poor processability, low ductility, low service temperature and high brittleness, and explains the application of PLA materials in food packaging in recent years. Finally, the prospect and development of PLA biodegradable materials are given.
