BASF (Ludwigshafen, Germany; www.basf.com) recently announced the expansion of its bioplastic film, ecovio’s portfolio for extrusion coating on paper and board by adding a grade suitable for home and industrial composting of cold and hot food packaging.

The new extrusion coating grade, ecovio 70 PS14H6, is food-contact approved and shows excellent barrier properties against liquids, fats, grease, and mineral oil, besides temperature stability at boiling water (up to 100°C), BASF says.

As it offers adhesion for paper and board, its applications include cups and pots for dairy products (including frozen), wrappings for sandwiches and cereal bars, bowls and trays for sweets and snacks, and to-go cups for hot/cold drinks. The packaging, BASF adds, can be composted after usage, and it allows the product to achieve additional barrier properties by mono or multi-layer extrusion without adhesives.
