PLA stands for polylactic acid and is a resin made from corn starch. PLA is used to make clear compostable containers and PLA lining is used in cups and containers as an impermeable liner. PLA is biodegradable, and fully compostable. It uses 65 percent less energy to produce than conventional oil-based plastics and generates 68 percent fewer greenhouse gasses and contains no toxins.
PLA is very unique material since it is made from corn and not from petroleum. Regular plastics is made from petroleum while PLA is made from corn based resins which makes PLA non toxic and annually renewable resources.PLA is very environmentally friendly material since it is made from renewable resource â Corn.Plastics products may take upto thousand years to degrade while PLA products biodegrade within 3-6 months in a composting system. The PLA clear products are heat resistant to 110 degrees Fahrenheit.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) .
