Polylactic acid (PLA) is a novel bio-based and renewable biodegradable material, which is made from starch materials proposed by renewable plant resources (such as maize and cassava). Starch raw materials were saccharized to get glucose, and then high purity lactic acid was made by fermentation of glucose and certain strains, and then POLylactic acid with a certain molecular weight was synthesized by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature under specific conditions, and eventually generate carbon dioxide and water. It does not pollute the environment, which is very beneficial to the protection of the environment and is recognized as environmentally friendly material.

ADVANTAGE OF PLA

1. Has good biodegradability, is an environmentally friendly material
2. Good mechanical and physical properties;
3. Good compatibility and degradability;
4. Has good gloss and transparency;
5. Has the best tensile strength and ductility;
6. PLA film has good air permeability, oxygen permeability and carbon dioxide permeability. It also has odor isolation properties.
7. Incineration of Polylactic acid will never release toxic gases such as nitrogen compounds and sulfides.

The absolutely harmless nature of polylactic acid to the human body gives polylactic acid unique advantages in the field of disposable tableware, food packaging materials and other disposable products;
The biomedical industry is the earliest application field of polylactic acid;
Used for packaging fresh fruits and vegetables in large supermarkets.

Injection molding application: PLA mixed modified degradable material can not only be molded quickly, but also is an ideal material for disposable tableware, quilts and flower pots in terms of heat resistance and safety.
Extrusion processing application: PLA mixed modified degradable material is suitable for processing on common extrusion molding machines, and can be made into transparent, heat-resistant color and other extrusion products, which can be directly degraded into carbon dioxide and water after disposal.
Film processing: There are many plastic film forming methods, among which casting, extrusion and calendering are more common. PLA mixed modified and degraded raw materials can be adapted to most traditional equipment and processed into films through various processes, such as agricultural mulching films for garbage bags and shopping bags.
