PLA stands for Polylactic Acid, a compostable bioplastic derived from plant sugars. Glucose is extracted from milled corn. It is then fermented to produce lactic acid, which is processed into a polymer and made into pellets. PLA is used in Vegware clear products like cold cups and deli containers, and to line our board-based products. CPLA is crystallised PLA, used when more heat resistance is needed, like with our lids and cutlery.
