Biodegradable films were prepared via method of solvent casting from modified starch, chitosan and polyvinyl alcohol by cross-linking, whereas, polyethylene glycol was used as a plasticizer. Films were evaluated for their mechanical property (tensile strength and elongation) and vapor barrier properties under storage conditions for up to a three month period. A decrease in both the tensile strength and % elongation from from 27.46 ' 21.51 Mpa and 7.09 ' 4.91 %, respectively, was observed over the storage period. The water permeation capacity of film was 1.45 x 10-7 g/hm2mmHg on day one, and reduced to 1.10 x 10-7 g/hm2mmHg by day 30.
