Biodegradable, liquid impervious multilayer film compositions are disclosed. In particular, the films comprise composite structures derived from multilayer combinations of biodegradable polymers. The biodegradable polymers are selected from the categories of moisture sensitive polymers, thermally sensitive polymers, mechanically limited polymers, polymers not easily processed into films, hydrolytically cleavable polymers, and degradable elastomers. Optionally, the multilayer films may further comprise additional adhesive tie layers. The biodegradable pol...
A biodegradable liquid-impervious multilayer film comprising: a first polymer film layer and a second polymer film layer joined to said first layer; said polymer film layers comprising a thermoplastic polymer capable of forming a film by a melt process, said thermoplastic polymer being selected from the group consisting of: (a) moisture sensitive polymers selected from the first group consisting of interpenetrated networks of destructurized starch, mixtures of destructurized starch, thermoplastic polyvinyl alcohol compositions, hydroxypropyl cellulose, a...
