ABSTRACT:
A paperboard composite for use in packaging applications includes paperboard adhered to a backing structure, providing enhanced wet tear strength. The backing structure includes an oriented polymer film and a reinforcing scrim, bonded together by a thermal bonding layer. In one embodiment of the invention, the parts of the backing structure are of similar chemical composition, thereby facilitating recycling of scraps and other waste.
