Polylactic acid or polylactide (PLA, Poly) is a biodegradable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States and Canada), tapioca roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world).eing able to degrade into innocuous lactic acid, PLA is used as medical implants in the form of anchors, screws, plates, pins, rods, and as a mesh. Depending on the exact type used, it breaks down inside the body within 6 months to 2 years.
PLA is very unique material since it is made from corn and not from petroleum. Regular plastics is made from petroleum while PLA is made from corn based resins which makes PLA non toxic and annually renewable resources.PLA is very environmentally friendly material since it is made from renewable resource â Corn.Plastics products may take upto thousand years to degrade while PLA products biodegrade within 3-6 months in a composting system. The PLA clear products are heat resistant to 110 degrees Fahrenheit.ur cutlery products and coffee lids are made from modified PLA which is called CPLA. PLA products donât offer high heat tolerance, and they can tolerate only upto 110 F. So, we make our cutlery products including knife, spoon, fork, stirrer, testing spoon and coffee lids etc.from CPLA (modified PLA) .
