ABSTRACT:
Expanded articles have a compressible and resilient body including two biodegradable components. One component preferably is starch or a modified starch. Another component is a water insoluble, synthetic polymer, preferably a hydroxy-functional polyester. The article may be thermoformed, and has exterior surfaces with substantial resistance to moisture.
