常见的生物降解塑料包含什么材料

生物降解塑料是指一类由自然界存在的微生物如细菌、霉菌（真菌）和藻类的做用而引起降解的塑料。 生物降解颗粒厂家认为理想的生物降解塑料是一种具有优良的使用性能、废弃后可被环境微生物完全降解、被无机化而成为自然界中碳素循环的一个组成部分的高分子材料。

Biodegradable plastics refer to a kind of plastics degraded by natural microorganisms such as bacteria, molds (fungi) and algae. Biodegradable particle manufacturers believe that the ideal biodegradable plastic is a kind of polymer material with excellent use performance, which can be completely degraded by environmental microorganisms after being discarded, and become an integral part of the carbon cycle in nature.

“纸”是一种典型的生物降解材料，而“合成塑料”则是典型的高分子材料。因此，生物降解塑料是兼有“纸”和"合成塑料"这两种材料性质的高分子材料。

"Paper" is a typical biodegradable material, while "synthetic plastic" is a typical polymer material. Therefore, biodegradable plastics are polymer materials with the properties of both "paper" and "synthetic plastics".

PLA（polylactic acid）也称为聚乳酸，其原料为乳酸，原料充分而且可以再生，主要以玉米、木薯等为原料。

PLA (polylactic acid) is also called polylactic acid. Its raw material is lactic acid. The raw material is sufficient and renewable, mainly corn, cassava, etc.

聚乳酸的生产过程无污染，而且产品可以生物降解，实现在自然界中的循环，因此是理想的绿色高分子材料，是生物基生物降解塑料的代表之一。

The production process of polylactic acid is pollution-free, and the product can be biodegradable to achieve recycling in nature. Therefore, it is an ideal green polymer material and one of the representatives of bio based biodegradable plastics.

PBAT兼具PBA（聚已二酸丁二醇指）和PBT（聚对苯二甲酸丁二醇酯）的特性，既有较好的力学性能，又有较高的延展性和破裂延长率，还具有优良的生物降解性，是一种性能优异的全生物可降解塑料。

PBAT has the characteristics of both PBA (polybutylene adipate) and PBT (polybutylene terephthalate). It has not only good mechanical properties, but also high ductility, fracture elongation and excellent biodegradability. It is a fully biodegradable plastic with excellent performance.
