PLA and CPLA compostable plastic are the most common compostable plastics, often made from cornstarch with other vegetables which make them sustainable, compostable and renewable. CPLA is Crystallized PLA, meaning that it is heat resistant and useful for food service items such as cutlery, takeaway food containers, coffee cup lids and soup containers. It is not transparent but often seen as white unless charcoal is added to create a black color. PLA is used for cold food service items such as cups, salad containers, deli posts, lids, bags (such as trash bags) and clear windows in sandwich boxes or bags and is transparent. PLA and CPLA are also recognized as non-toxic which allows them to be utilized in medical environments such as medical implants, orthopedic devices and drug delivery systems.
