PLA (polylactic acid) biodegradable materials refer to a class of materials degraded by the action of microorganisms existing in nature, such as bacteria, molds (fungi) and algae.
Chinese alias: poly (lactide) (also known as polylactic acid)
English name: Polylactide, Polylactic Acid, PLA for short
Polytrimethylene carbonate; 1, 3 - Dioxan - 2 - one homopolymer
Molecular formula :(C3H4O2)n

PLA is lactic acid as the main raw material, mainly from cassava, corn, sugarcane and other herbs to obtain starch and sugar through bacterial fermentation of lactic acid, and finally form a polymer polymerization poly (PLA). Raw materials are plentiful and renewable.

The whole production process of POLY (lactic acid) and poly (lactic acid) fiber is not involved in any harmful substances, which is a biological manufacturing technology product strongly advocated by the national "twelfth Five-Year Plan".
It is a kind of polymer material with excellent performance, can be completely decomposed by environmental microorganisms after waste, and finally become a part of the carbon cycle in nature by inorganic.

The characteristics
（1）Polylactic acid (PLA) is a new type of biodegradable material with good biodegradability. After use, it can be completely degraded by microorganisms in nature and eventually generate carbon dioxide and water, which does not pollute the environment.
（2）Polylactic acid (PLA) film has good air permeability, oxygen permeability and dioxide-carbon permeability, it also has the characteristics of odor isolation, is the only biodegradable plastic with excellent bacteriostatic and mildew resistance.
(3) When PLA is incinerated, its combustion heat value is the same as that of incinerated paper, which is half of that of incinerated traditional plastics (such as polyethylene), and the incineration of PLA will definitely not release nitrogen, sulfide and other toxic gases. The body also contains lactic acid as a monomer, indicating the safety of the breakdown product.

It has the advantages of both synthetic fiber and natural fiber, and has the characteristics of complete natural circulation and biological decomposition. Compared with conventional fiber materials, corn fiber has many unique properties, so it has been widely valued by the international textile industry.
In order to actively respond to the global call for environmental protection and keep up with market demand, Zhejiang Yanpeng Non-woven Machinery Co., Ltd. has successfully developed and put into production PLA fully degradable non-woven production line and other recycling production lines, striving to create the world's first non-woven industrial chain solution supplier.
