PURPOSE:To manufacture an aluminum metallized laminated film excelled in bond strength by a method wherein ethylene-based copolymer resin containing the specified amounts of (meth)acrylic acid and of (meth)acrylic acid alkyl ester is extrusion-laminated onto an aluminum metallized surface. CONSTITUTION:Ethylene-based copolymer resin, which contains 1-15 wt.% of acrylic acid or methacrylic acid unit copolymerized with ethylene and 5-40 wt.% of acrylic acid alkyl ester or methacrylic acid alkyl ester unit, is extrusion-laminated onto the aluminum metallized surface of an aluminum metallized propylene-based resin film. The propylene-based resin film is a uniaxially or biaxially stretched film having the thickness of about 5-150 m. Further, the aluminum metallized propylene-based resin film is a film, on the surface of which aluminum is metallized by the thickness of about 100-700 Angstrom by the publicly known metallizing method such as vacuum metallizing method, sputtering method or the like after the pretreatment such as corona discharge treatment, anchor coat or the like is applied on the surface of the film, when necessary. |
