摘要
工业技术的迅猛发展,很多强度高、质量轻加工性能优越的高分子材料广泛应用于包装领域。但是很多高分子材料的降解周期十分漫长,对环境造成的巨大危害也成为世界性难题。目前世界各位研究开发出多种可生物降解材料以解决环境问题。本文主要介绍聚乳酸、聚羟基脂肪酸酯、壳聚糖、淀粉基塑料及几种新型可降解材料及在包装领域应用。
With the rapid development of industrial technology, many high-strength, light-weight and processable polymer materials are widely used in packaging field. However, the degradation cycle of many polymer materials is very long, and the enormous harm to the environment has become a worldwide problem. At present, many biodegradable materials have been developed to solve environmental problems. This paper mainly introduces polylactic acid, polyhydroxyalkanoate ester, chitosan, starchbased plastics, several new degradable materials and their applications in packaging field.
