A biodegradable shaped product comprising an expanded high amylose starch product having at least 45% by weight amylose content, said expanded product having a low density, closed cell structure with good resilience and compressibility. Another embodiment provides a biodegradable packaging material comprising an expanded, low density, closed cell starch product, the starch having at least 45% by weight amylose content and the expanded product having a bulk density of less than about 32.0 kg/m<3> (2.0 lb/ft<3>), a resiliency of at least about 50%, and a compressibility of from about 100 to 800 g/cm<2>. |
