Abstract
Described herein is a heat-seal coating which, when going through the recycled paper making process, will readily break down without any major amount of by-product that needs to be landfilled; can be made into paper again; breaks down in a commercial composting facility; and decomposes into basic materials such as carbon dioxide, carbon monoxide and water. The heat seal coating or top coat comprises three components: (1) a barrier polymer; (2) a polymer that provides some barrier properties and softness to the formulation; and, (3) a heat-curable adhesive.
