Thermoplastic starch composites have attracted significant attention due to the rise of environmental pollutions induced by the use of synthetic petroleum-based polymer materials. The degradation of traditional plastics requires an unusually long time, which may lead to high cost and secondary pollution. To solve these difficulties, more petroleum-based plastics should be substituted with sustainable bio-based plastics. Renewable and natural materials that are abundant in nature are potential candidates for a wide range of polymers, which can be used to replace their synthetic counterparts. This paper focuses on some aspects of biopolymers and their classes, providing a description of starch as a main component of biopolymers, composites, and potential applications of thermoplastics starch-based in packaging application. Currently, biopolymer composites blended with other components have exhibited several enhanced qualities. The same behavior is also observed when natural fibre is incorporated with biopolymers. However, it should be noted that the degree of compatibility between starch and other biopolymers extensively varies depending on the specific biopolymer. Although their efficacy is yet to reach the level of their fossil fuel counterparts, biopolymers have made a distinguishing mark, which will continue to inspire the creation of novel substances for many years to come.
由于使用合成石油基聚合物材料导致环境污染加剧，热塑性淀粉复合材料受到了广泛关注。传统塑料的降解需要很长时间，这可能导致成本高昂和二次污染。为了解决这些难题，应更多地用可持续的生物基塑料替代石油基塑料。自然界中丰富的可再生和天然材料是多种聚合物的潜在候选材料，可用于替代合成聚合物。本文重点介绍了生物聚合物及其类别，描述了淀粉作为生物聚合物的主要成分、复合材料以及热塑性淀粉基材料在包装应用中的潜在应用。目前，与其他成分共混的生物聚合物复合材料已展现出多种增强性能。当天然纤维与生物聚合物结合时也观察到了同样的现象。然而，应当注意的是，淀粉与其他生物聚合物之间的相容程度因具体的生物聚合物而异。尽管它们的功效尚未达到化石燃料同类产品的水平，但生物聚合物已经崭露头角，在未来许多年将继续激发新型材料的创造。
