THERMOPLASTIC BIODEGRADABLE AND COMPOSTABLE OPAQUE FILM AND METHOD FOR PRODUCING THE SAME

摘要

The invention relates to an opaque biodegradable and compostable film consisting of biodegradable and compostable polymers which are filled to up to 49 wt. % with inorganic fillers and which are monoaxially or biaxially stretched. The film may contain other additives to improve its workability. These additives can also be nucleation agents or anti-blocking agents which are part of the inorganic fillers and which also produce an opaque surface.
