A new certified home as well as industrial compostable extrusion coating grade for cold and hot food packaging has been added by BASF to its partially biobased plastic Ecovio (a blend of BASF’s Ecoflex biodegradable aliphatic copolyester and 45% PLA) for use on paper and board. In addition to being food-contact approved, Ecovio 70 PS14H6 reportedly shows excellent barrier properties against liquids, fats, grease, and mineral oil as well as temperature stability at boiling water (up to 212°F/100°C).
The new grade is also characterized by outstanding adhesion to many types of paper and board, enabling paper applications like cups and pots for dairy products (also frozen), wrappings for sandwiches and cereal bars, bowls and trays for sweets and snacks as well as to-go cups for hot/cold drinks and soup. After usage, food packaging made of paper coated with Ecovio 70 PS14H6 can be composted either in garden home compost or industrial composting facilities according to national legislation.
