碳中和趋势下的包装材料绿色化前景

Green Prospect of Packaging Materials under the Trend of Carbon Neutrality

如今全球生产的塑料中约99%都是石油基来源的,其中有接近四成消耗在了各色产品包装上。主要回顾并展望了可再生聚酯作为可再生塑料在绿色包装的道路上里程碑式成果,描述了不同类别的聚酯(包括聚对苯二甲酸乙二醇酯及其可再生类似物、聚乳酸、聚羟基脂肪酸酯和聚环氧酸酐)作为绿色包装材料的潜在价值,结构性能相关性,面临的挑战,可能的环境足迹和未来的研究方向。

Approximately 99%of the plastic produced globally today comes from petroleum based sources,of which nearly 40%is consumed in various product packaging.This paper mainly reviews and prospects the landmark achievements of renewable polyester as a renewable plastic on the path of green packaging,and describes the potential value,structural performance correlation,challenges,potential environmental footprint,and future research directions of different categories of polyester(including polyethylene terephthalate and its renewable analogues,polylactic acid,polyhydroxyfatty acid esters,and polyepoxide anhydride)as green packaging materials.
