Ecovio®, the compostable copolyester made by BASF, and other renewable materials are used in the fabrication of these bags. They are easy to manipulate, lightweight, waterproof and are more practical than paper bags. Our certified compostable bags come in a tinted green colour and are available on a compact perforated roll. Their sizes and thicknesses range from 0.7 to 1 Mil. The bags are certified by the Biodegradable Plastics Institute (BPI) and the Bureau de normalisation du Québec (BNQ), successfully meeting the standards of the American Society for Testing and Materials (ASTM D6400). Polykar’s certified compostable bags also hold UL 126 Environment’s ECOLOGO® certification.
