What is PLA

Come from nature,returning to nature

Poly (lactic acid) (PLA) is a novel biodegradable material made from starch from renewable plant resources such as corn.Starch raw material is saccharified to get glucose, which is then fermented by glucose and certain strains to produce lactic acid with high purity, and then polylactic acid with certain molecular weight is synthesized by chemical synthesis.It has good biodegradability, and can be completely degraded by microorganisms in nature after use, eventually generating carbon dioxide and water, which does not pollute the environment, which is very beneficial to environmental protection, and is recognized as environmentally friendly material.Care for the earth, you and I have a responsibility.World's carbon dioxide emissions in 2030, according to news reports in global temperature will rise to 60 ℃, common plastic processing methods is still burning cremation, caused a large number of greenhouse gases into the air, and the plastic poly (lactic acid) (PLA) is buried in the soil degradation, the carbon dioxide directly into the soil organic matter or is absorbed by plants, not into the air, won't cause the greenhouse effect.


process

1) materials
Husk crops such as corn are crushed to extract starch, which is then turned into unrefined glucose. Many technologies have overcome the crushing process to extract raw materials directly from large amounts of crops.
2) fermentation
Fermenting glucose in a manner similar to beer or alcohol, the glucose becomes lactic acid, which is added to the body's muscle tissue as food.
3) intermediate products
The lactic acid monomer is converted into the intermediate product, lactolactate, by a special concentration process.
4) polymerization
After the lactide monomer is purified by vacuum, the ring opening is completed in a solvent free process to polymerize the monomer.
5) polymer modification
Due to the difference in molecular weight and crystallinity of the polymer, there is a wide range of material properties. Therefore, PLA can be modified in different applications.



Using corn and potato as raw materials, we prepared optical pure l-lactic acid or d-lactic acid by microbial fermentation. Moreover, l-lactic acid can be completely absorbed by human body than d-lactic acid, without any toxic and side effects.

Pla nonwoven bag is our main product this year,if you are interested,we can have a good start here.
