  • COMPOSITION COMPRISING ETHYLENE COPOLYMER AND POLYOLEFIN
    Publication number: 20140034225
    Abstract: Disclosed are compositions of ethylene/(meth)acrylate copolymers, polyolefins (for example, polyethylene and polypropylene), tackifier resins and optional fillers that provide strong hermetic adhesion to fluoropolymers such as PCTFE. These compositions can be useful as an adhesive layer in multilayer structures prepared by extrusion lamination. Also disclosed are packages, such as thermoformed blister packs, rigid containers and pouches that comprise these multilayer structures.
