Renewable Thermoplastic Starch-Polyolefin Compositions Comprising Compatibilizer and Flexible Thin Films Made Therefrom

Abstract

A compatibilized thermoplastic polymer composition having from 5% to 95% bio-based content and comprising thermoplastic starch; polyolefin; and an effective amount of compatibilizer. The compatibilizer can include polar homopolymers and copolymers with inherent polyolefin compatibility; non-polymeric materials with both polar and non-polar functionality; low molecular weight materials with both polar and non-polar functionality; and bulk phase/in-situ compatibilizers. Alternatively, polyolefin can be modified to function as the compatibilizer. The composition is suitable for making flexible thin films and packaging components, such as those used for packaging consumer products.
