SYSTEMS AND METHODS FOR COMPOSTABLE BAGS

A film structure includes a first outer layer system, a second outer layer system, and a core layer system. The first outer layer system includes at least one layer formed of a starch polymer thermoplastic bioresin. The second outer layer system includes at least one layer formed of a starch polymer...

Zusammenfassung:	A film structure includes a first outer layer system, a second outer layer system, and a core layer system. The first outer layer system includes at least one layer formed of a starch polymer thermoplastic bioresin. The second outer layer system includes at least one layer formed of a starch polymer thermoplastic bioresin. The core layer system includes at least one layer formed of a modified Polyvinyl Alcohol (PVOH). The first outer layer system, the second outer layer system, and the core layer system are compostable.
