Abstract
Methods of making articles are provided in which a self-supporting structure formed of natural polymer has a self-adherent, moisture resistant thermoplastic film comprising gelatinized starch and a hydroxy-functional polyester on the structure surface. The self-supporting structure preferably is a starch and polyvinyl alcohol blend in an expanded form. The articles typically do not delaminate even when soaked in water, and are biodegradable.
