Abstract

PURPOSE:To manufacture laminated moldings excellent in productive efficiency and adhesive strength by a method wherein polyethylene resin mixed with special organic peroxide is extruded and molded at a desired temperature and compressed on to the base material as it is melted. CONSTITUTION:An organic peroxide[such as t-butyl peroxide (said temperature; 167 deg.C), t-butyl cumyl peroxide (said temperature; 120 deg.C)]wherein the extrusion molding temperature is 100-170 deg.C when the half-life period is 10hr is used. In other words, resin composition having said organic peroxide mixed at 0.01-0.5pts.wt. to 100wt.pts of polyethylene resin is extruded from a T die 1 at 260-360 deg.C in the form of film, while it is melting yet it is compressed on to the base material[such as polyethylene (co-)polymer film]2 with a pressure roll 3 and a cooling roll 4 and then the laminated molding 5 is taken off through a guide roll 6 to obtain the product.
