食品包装用生物塑料研究进展

在白色污染和石油危机日趋严重的今天,具有生态友好特征和可持续性的生物基质-生物分解塑料有望替代部分石油基塑料成为一种新型基础原材料,在农业、包装、生物医用等领域已开始显示出巨大的市场潜力。本文介绍了聚乳酸、淀粉基塑料、聚羟基烷酸酯等几类最有可能率先实现产业化并用于食品包装材料的生物基质-生物分解塑料,对其在食品包装材料应用方面所具有的优势和存在的问题进行了评价,并对目前国内外在这几类材料的生产和应用技术及产业化等方面的最新进展进行了归纳。

Advances of bio-plastics in food packaging application

Biomass-based biodegradable plastics characteristic of ecological concern and sustainability are expected to become a novel category of basic raw materials in a wide range of potential applications such as agriculture,packaging and biomedical,when white pollution and oil crisis are increasingly serious today.The main categories of biomass-based biodegradable plastics,including poly(lactic acid),starch-based plastics and poly hydroxylalkanoates were introduced,which may most probably take the lead to be comm...
