IMPACT RESISTANT BIODEGRADABLE COMPOSITIONS AND METHODS FOR THE PRODUCTION THEREOF

摘要

The present invention concerns a biodegradable starch ester composition, a method for preparation thereof and use of such composition. Said thermoplastic, biodegradable starch composition comprises from 50 to 90 wt-% of a plasticized starch ester and from 10 to 50 wt-% of at least one other biodegradable plastic. It has shown impact strengths considerably greater than either of the components alone. Such compositions are especially desirable in packaging industry, wherein they formed into packages as such or as raw material providing additional features for product performance.
