Abstract

The invention relates to biodegradable, thermoplastic shaped bodies, especially single-layer or multilayer films, which exhibit an improved stability with regard to hydrolysis, an improved stress cracking behavior, and an improved behavior with regard to biodegradation. The inventive thermoplastic shaped bodies consist of a blend comprised of at least two different biodegradable polymers.
