Abstract
The present invention relates to a biodegradable paperboard-based package for various food products. The package utilizes a novel heat-sealable laminate structure wherein the exterior gloss heat-sealable layer is a degradable polymeric resin material such as a polyvinyl alcohol resin or a starch based low density polyethylene polymer resin. Utilization of the material in a novel fashion accelerates the paperboard substrate's degradative properties and tendencies.
