Abstract

The present invention relates to a polymer composition comprising at least 20.0 wt.-%, based on the total weight of the polymer composition, of at least one biodegradable polymer resin, from 0.1 to 20.0 wt.-%, based on the total weight of the polymer composition, of at least one polyolefin selected from polyethylene and/or polypropylene and from 5.9 to 60.0 wt.-%, based on the total weight of the polymer composition, of an inorganic filler material dispersed in the at least one polyolefin and the at least one biodegradable polymer resin, a process for the preparation of such a polymer composition, the use of an inorganic filler material for increasing the thermal stability and/or processability of a polymer composition, the use of the polymer composition for the preparation of an article as well as in a process selected from extrusion process, co-extrusion process, blown film extrusion process, cast film extrusion or sheet extrusion process, extrusion coating process, injection molding process, blow molding process, thermoforming process as well as an article comprising the polymer composition.
