The Pela Case is made of Flaxstic®, which is comprised of compostable bioplastic elastomer and flax straw materials. Our material has been tested to be safe and free of phthalates, BPA, cadmium and lead and is verified to meet child safety standards in the U.S., Canada, Europe, Australia and New Zealand. Our base material meets U.S. (ASTM D6400-04) and E.U. (EN 13432) standards for composting in an industrial composting facility and has a lower carbon footprint and lower greenhouse gas emissions than traditional plastic. It can also be left to biodegrade in a home composting environment.
