PLA and CPLA are popular compostable plastics typically made from cornstarch and other vegetable materials, making them sustainable, compostable, and renewable. CPLA, or Crystallized PLA, is heat-resistant and ideal for food service items like cutlery, takeaway containers, coffee cup lids, and soup containers. It is not transparent and is usually white, although charcoal can be added to create a black color. PLA, on the other hand, is used for cold food service items such as cups, salad containers, deli pots, lids, bags (like trash bags), and clear windows in sandwich boxes or bags, and it is transparent. Both PLA and CPLA are non-toxic, making them suitable for medical applications such as implants, orthopedic devices, and drug delivery systems.
