Compostable polymer compositions with barrier properties and the method of making thereof

Abstract

The invention includes compositions and methods of production of biodegradable polymer resins with high barrier and resistance against water, water vapor, and oxygen. The biodegradable resin compositions of the invention comprise one or more biodegradable thermoplastic polymers, one or more barrier agents, one or more oils, and optionally one or more substrate adhesion agent and other optional additives. The biodegradable resin compositions of the invention are produced using conventional polymer processing techniques such as extrusion and batch compounding and can be used directly as a single or multi-layer barrier or used as a coating on a substrate such as paper for packaging applications. The method of coating of the biodegradable resin compositions of the invention on substrates can be done via conventional melt or solvent based coating techniques.
