basf and feinpappenwerk gebr schuster are working jointly on a solution for a combined migration and grease barrier on recycled cartonboard.basf&39s ecovio ps 1606 biopolymer is applied to recycled cartonboard in an extrusion coating process. this enables the proportion of recycled paper fibres in fast food packaging to be increased while simultaneously making it industrially compostable.ecovio is biobased and biodegradable according to american standard astm 6400 and european standard en 13432. the polymer coating applied to the cartonboard is many times thinner than a human hair, but provides the packaging with outstanding protection against potential migration of undesired substances as well as offering high greaseproofness and liquid tightness.cartonboard packaging produced on this basis is said to be more than 90 biobased, recyclable and industrially compostable.
