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.
Ingeo is generally made from corn; it is brand name of PLA which is produced by US based company called NatureWorks. Ingeo perform much like traditional plastics, but are made from annually renewable resources like corn plants and it is compostable and biodegradable.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) .
