Biopolymers Are a New Barrier Family  

 Biopolymer Coating Biodegradable coatings are tailor-made polymers offering humidity and oxygen barriers, as well as sealability. Biopolymers are based on raw materials which come from natural crops or from fossil sources, or combinations of these. Biopolymer coated paperboard breaks down to humus and CO2.
Stora Enso has developed biopolymer coatings for years and today biodegradable coating options are available for a number of our board grades. Cupforma Classic Bio meets the compostability requirements of the EN 13432 and ASTM 6400 standards. In recycling schemes, biodegradable products are primarily intended into the collection of compostable materials.
