PLA Plastic Dinner Plate
The resin identification code of PLA (Polylactic acid) is No.7. Monomers come from lactic acid converted from plant starch (corn, sweet potato, etc.). Polylactic acid can generally be decomposed under appropriate environmental conditions. The CPLA (Crystalline PLA) has the same properties as polylactic acid. The main difference is that CPLA is a heat-resistant material, which can be molded into tableware.
