What material is pla?

PLA scientific name polylactic acid, commonly known as corn plastic, is a completely biodegradable environmental protection material.

As a new type of "green plastic", polylactic acid (PLA) is made by extracting starch from renewable plant resources, making lactic acid by microbial fermentation, and then polymerizing.

PLA has excellent machinability and biodegradability, and can be used in most synthetic plastics. PLA can be COmpletely degraded into co after being discarded And h? O, does not pollute the environment, and can replace some petroleum-based products. It is suitable for the existing solid waste treatment system.

PLA caters to the requirements of developing circular economy and realizing sustainable development in 2 1 century, and is recognized by the industry as a new type of "ecological material" with the most promising development prospect in the new century. PLA products help to solve the "white" pollution caused by polyolefin packaging materials and reduce dependence on petroleum resources.

The advantages of polylactic acid are:

1, good mechanical and physical properties. Poly (lactic acid) is suitable for various processing methods such as blow molding, thermoplastics, etc., which is convenient to process and widely used. It can be used to process various plastic products, packaged foods, fast food lunch boxes, non-woven fabrics, industrial and civil fabrics. Then processed into agricultural fabrics, health fabrics, rags, sanitary products, outdoor anti-ultraviolet fabrics, tent fabrics, floor mats, etc., and the market prospect is very promising.

2. Good compatibility and biodegradability. Poly (lactic acid) is also widely used in the medical field, such as the production of disposable infusion sets, detachable surgical sutures, and low molecular weight poly (lactic acid) as drug slow-release packaging agents.

3. Polylactic acid (PLA) has its own unique characteristics besides the basic characteristics of biodegradable plastics. The strength, transparency and climate change resistance of traditional biodegradable plastics are not as good as ordinary plastics.
