Abstract
A method for manufacturing a compostable film for sealing a capsule for making beverages involves arranging an outer barrier layer made of a compostable material, the compostable material being paper, or regenerated cellulose, arranging a filtering element, and extruding and casting, directly onto the outer barrier layer, an inner layer, intended to come into contact with the capsule to be sealed and made of a compostable biopolymer with heat-sealing properties so that the filtering element is at least partially incorporated in the compostable biopolymer.
