Polylactic Acid(PLA) Granule
Polylactic acid (PLA) is a new type of biodegradable material made from starch raw materials proposed from renewable plant resources such as corn. Starch raw materials are fermented to produce lactic acid, which is then converted into polylactic acid through chemical synthesis. It has good biodegradability and can be completely degraded by microorganisms in nature after use, ultimately generating carbon dioxide and water without polluting the environment. This is very beneficial for protecting the environment and is recognized as an environmentally friendly material.

PLA is a biodegradable thermoplastic polymer made mainly from renewable resources such as corn starch or sugar cane. It has a wide range of applications in several fields, including but not limited to:
1. Packaging materials: Due to its good transparency and printing properties, PLA is often used in the manufacture of food packaging, beverage cups and other disposable products, which can biodegrade after use and reduce environmental pollution.
2. 3D printing: PLA is one of the most commonly used materials in 3D printing because it is easy to print and does not require a heated bed, reducing the possibility of warping. Its low odor and non-toxic properties also make it ideal for indoor use.
3. Textile fibers: PLA can also be processed into fibers for the production of clothing fabrics, which have good air permeability and soft feel.
4. Medical materials: Due to the good biocompatibility of PLA, it can be used in the production of sutures, fracture fixators and other medical devices, which can gradually degrade and be absorbed in the body.
5. Agricultural film: In agriculture, PLA film can replace traditional PE (polyethylene) film for covering crops, which not only helps to increase crop yield, but also can decompose naturally at the end of the use cycle to avoid soil pollution.
1.Packing:25kg/bag, or per your requirement.
2.Storage:The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air.
3.Transportation:During transportation, the product should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
