Polylactic acid PLA is obtained by saccharification of starch raw materials to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature under specific conditions, eventually generating carbon dioxide and water, and does not pollute the environment. This is very beneficial to environmental protection and is recognized as an environmentally friendly material.
Polylactic acid has good thermal stability, the processing temperature is 170～190℃, and it has good solvent resistance. It can be processed in various ways, such as extrusion, spinning, biaxial stretching, injection molding, and blow molding. In addition to being biodegradable, products made of polylactic acid have good biocompatibility, gloss, transparency, hand feel and heat resistance. Polylactic acid is a material with higher food contact safety, because the monomer of polylactic acid-lactic acid is a food additive and a biocompatible substance, which can be completely absorbed by the body through metabolism. Tableware made of polylactic acid is safe and non-toxic, does not contain bisphenol A, and does not contain plasticizers. It can be used in microwave ovens and can replace traditional melamine and general petroleum-based plastics.
Polylactic acid (PLA) also has a certain degree of bacteria resistance and UV resistance, so it has a wide range of uses. It can be used as baby products, food containers, packaging materials, fibers and 3D printing consumables. It is currently mainly used in clothing (underwear, Outer clothing), industry (construction, agriculture, forestry, papermaking) and medical and health fields.

PUDA masterbatch packing machine:
PUDA usually recommend free flow packing machine for masterbatch. Because masterbatch has good fluidity and big bulk density. Free flow packing machines has three types: without hopper, single hopper, double hoppers. Of course double hopper can pack fastest. So offer us your requirement, PUDA will make a designing for you.
