What is PLA (polylactic acid)biodegradable material and what is the advantages in Europe countries

October 30,2023

PLA polylactic acid is the main raw material of lactic acid, mainly from cassava, corn, sugarcane and other herbaceous plants to obtain starch and sugar, lactic acid is obtained by bacterial fermentation, and finally forms the polymer of polylactic acid (PLA). The raw materials are abundant and renewable.

Natural attributes and advantages

The pH value is about 6, showing weak acidity.

The inhibition rate of mites was 71.39%. The conclusion was that it had the effect of mite control.

The results showed that the loss rate of Staphylococcus aureus, Candida albicans and Escherichia coli was more than 98%( SGS authority test)

There are no antibacterial, anti mite drugs or other chemical substances added in the production process, which is the performance of its natural properties.

Natural self extinguishing: nonflammable, oxygen limiting index higher than polyester, nylon.

The heat preservation performance is 1.8 times higher than that of high quality cotton core( Test data)

Good rebound, strong fluffy, smooth handle, quick drying, anti ultraviolet.


Polylactic acid has good thermal stability, processing temperature 170 ~ 230 ℃, good solvent resistance, and can be processed in many ways, such as extrusion, spinning, biaxial drawing, injection blow molding. In addition to biodegradation, the products made of PLA have good biocompatibility, gloss, transparency, handle and heat resistance, as well as certain bacterial resistance, flame retardancy and UV resistance, so they are widely used.

Biodegradable materials used in medicine, human organs and other fields can be designed and manufactured by modification, which are free of plasticizer, heavy metal, non-toxic chemicals, bisphenol A, petroleum resources and food contact safety;

Molding process can choose injection molding, extrusion, blow molding, blister, suitable for household daily necessities, tableware products in contact with food or oral cavity, etc;

It can be widely used as packaging materials, fibers and non-woven fabrics,  mainly used in clothing (underwear, coat), industry (construction, agriculture, forestry, paper) and medical and health fields.
