The composite film for the cable wrapping layer includes a PE film layer, a PET film layer laminated at the PE film layer, an aluminum foil layer laminated at the PET film layer, and a bonding layer arranged between the PET film layer and the aluminum foil layer. The PE film layer is made of raw materials having the following parts by weight: 40-45 parts of LLDPE with a melt index of 0.9-1.1 g/10 min and a density of 0.920-0.922 g/cm.sup.3, 35-40 parts of m-LLDPE with a melt index of 1.9-2.1 g/10 min and a density of 0.917-0.920 g/cm.sup.3 and 15-25 parts of ethylene-vinyl acetate copolymer.

A rubber-metal bonded article with an adhesion promoter in the rubber selected from neoalkoxy zirconates and polyimides. Articles requiring compressed rubber exhibit improved retention of compressive strain after assembly of the article and activation of the adhesion promoter. Also claimed is a method wherein a rubber composition may be fully cured, then assembled between two substrates under compression, then the adhesion promoter activated to form the bond.
