Polylactic acid, also known as polylactide, belongs to the polyester family. Polylactic acid is a polymer obtained by polymerizing lactic acid as a main raw material.
The raw material source is sufficient and can be regenerated, and corn, cassava and the like are mainly used as raw materials.
The production process of polylactic acid is non-polluting, and the product can be biodegraded to achieve circulation in nature, so it is an ideal green polymer material.
PLA is completely derived from pure natural corn and is therefore a natural, non-toxic and 100% biodegradable material.
PLA polylactic acid raw materialPLA is an abbreviation for Poly Lactic AcidThe Chinese name is "polylactic acid".PLA raw materials come from corn. The process is to crush the corn kernels first. Filter out the starchAdd enzymes and other ingredientsTransform it into glucosePlus lactic acid bacteria fermented into lactic acida substance from which a polymer is producedIt is PLA.
After using PLA polylactic acid to make a sheet According to customer needs Design and manufacture related products From the lunch box, the bowl, the tableware, the plastic bag material can use PLA
The product itself is highly transparent Has good steel properties, natural non-toxic From process to recycling, about 40% reduction in carbon emissions
Although the heat resistance temperature is not high (50 °c or less) But there is also a new material CPLA Its heat resistance can reach 93 °c -100 °c
PLA is completely derived from reproducible natural plant resources Its properties are completely biodegradable, recyclable, compostable Environmentally friendly materials that are consistent with sustainability Non-toxic properties of raw materials Compliance with US Food and Drug Administration (FDA) safety certification testing
In conditional relative humidity 90% And in an aerobic environment of 58 °c -70 °c PLA polylactic acid products can be completely decomposed into water, carbon dioxide or methane by microorganisms. The decomposition time varies according to the size of each plastic product. On average, it takes at least 47 days to break down.
