To provide a resin film which comprises an ethylene/tetrafluoroethylene copolymer and which is to be used as, for example, a rubber plug lamination film to prevent breakage at the time of producing a laminated rubber plug. The resin film comprises an ethylene/tetrafluoroethylene copolymer and is characterized in that the product of the value of the endothermic peak height H (mW/mg) obtained by its DSC-analysis and the haze (%) measured at a thickness of 100 m, is from 0.1 to 0.2 (mW/mg.Math.%).

Silane-crosslinkable polymeric compositions comprising a polyolefin having hydrolyzable silane groups, an acidic silanol condensation catalyst, and a phenolic antioxidant. The phenolic antioxidant has a phenol-based moiety fused with a cyclic ether where the oxygen atom of the cyclic ether is located in the para position relative to the hydroxyl group of the phenol-based moiety. Such crosslinkable polymeric compositions can be employed in various articles of manufacture, such as in the wire and cable industry.
