Patent Number: 5756194
Docket Number: 5794
Serial Number: 8591923
Date Patented: 05/26/1998
Agency:

Abstract:
The invention uses biodegradable starch as a base material in the manufacture of
products such as, disposable dishes, utensils, bags and diapers. The invention involves a way to
coat starch-based articles with biodegradable polyesters films. Adherence to the starch substrate
is enhanced by an intervening layer of natural resin, which is applied by spraying an alcoholic
solution of shellac or rosin.
