Effect of compatibilizer additives on the technological and performance characteristics of biodegradable materials based on starch-filled polyethylene

The deformation and strength characteristics, as well as rheological properties and biodegradability of film materials prepared by hot pressing and slot extrusion methods from polyethylene-plasticized starch-compatibilizer blends were examined. Polyethylene with grafted itaconic acid served as compatibilizer. The formulation and technological parameters of preparation of biodegradable film materials were optimized to meet the technical performance criteria.
