<p>PROBLEM TO BE SOLVED: To provide a laminate manufacturing method using no anchor coat agent in laminating a polyethylene resin layer to a base material made of a polyester or polypropylene film. SOLUTION: In a laminate manufacturing method wherein a polyethylene resin is extruded in a molten state to be laminated to the bonding surface of a base material of which at least the bonding surface comprises a polyester or polypropylene film to form a laminate 1, flame treatment is applied to the bonding surface of the base material 3 and the polyethylene resin is extruded at about 300 deg.C to form a molten extruded film 5 which is, in turn, contact- bonded and laminated to the base material 3 to which flame treatment is applied to produce the laminate 1. In this case, surface oxidizing treatment such as corona discharge treatment, plasma treatment, anchor coat treatment or ozone treatment is not applied to the bonding surface.</p> |
