Abstract

A laminated material for packaging containers comprising polyvinyl alcohol or other water-soluble, thermoplastic resin layers disposed on both sides of a paperboard base material layer and other thermoplastic synthetic resin layers laminated thereon. An aluminum foil layer 5 may be provided over a polyolefin adhesive resin layer. The paper pulp can be readily separated from the polyethylene and other thermoplastic synthetic resins during the recycling process.
