生物降解塑料是指一類由自然界存在的微生物如細菌、霉菌（真菌）和藻類的做用而引起降解的塑料。生物降解顆粒廠家認為理想的生物降解塑料是一種具有優(yōu)良的使用性能、廢棄后可被環(huán)境微生物完全降解、被無機化而成為自然界中碳素循環(huán)的一個組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.

“紙”是一種典型的生物降解材料，而“合成塑料”則是典型的高分子材料。因此，生物降解塑料是兼有“紙”和"合成塑料"這兩種材料性質(zhì)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）也稱為聚乳酸，其原料為乳酸，原料充分而且可以再生，主要以玉米、木薯等為原料。

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.

聚乳酸的生產(chǎn)過程無污染，而且產(chǎn)品可以生物降解，實現(xiàn)在自然界中的循環(huán)，因此是理想的綠色高分子材料，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（聚對苯二甲酸丁二醇酯）的特性，既有較好的力學(xué)性能，又有較高的延展性和破裂延長率，還具有優(yōu)良的生物降解性，是一種性能優(yōu)異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.
