Patent ID: 7776428

Claim:
A multilayer film comprising: a first layer comprising a blend of diene elastomer, 5% to 30% by weight polyolefin, and 0.1 wt % to 2.0 wt % photoinitiator responsive to ultraviolet radiation, the polyolefin selected from the group consisting of polyethylene, ethylene propylene copolymer, ethylene butene copolymer, polypropylene, polybutene, polypentene, polymethylpentene, ethylene octene copolymer, and a combination thereof; and a second layer directly contacting and bonded directly to the first layer, the second layer including a fluoropolymer, the fluoropolymer being selected from the group consisting of a fluorinated ethylene propylene copolymer (FEP), a copolymer of tetrafluoroethylene and perfluoropropylvinyl ether (PFA), a copolymer of tetrafluoroethylene and perfluoromethyl vinyl ether (MFA), polychlorotrifluoroethylene (PCTFE), and a combination thereof, the second layer forming an outermost surface of the multilayer film.
