Greenlid uses only 100% natural and compostable materials such as birch, palm leaves, plant fiber, recycled cardboard, and bamboo for their products, and helps to keep plastic out of the environment with their use. Greenlid does not use PFAs (poly- and perfluoroalkyl substances) or any other flourinated chemicals that are often added to food packaging to provide grease and water resistance. A close relative of Teflon, PFAs and other fluorinated chemicals are considered “forever chemicals” and accumulate in the environment. Since these chemicals can permeate food, air, soil and water, they also pose a growing threat to our health. Exposure to PFAs has been linked to cancer, liver damage, thyroid disease, fertility issues, and possibly more.
