PROBLEM TO BE SOLVED: To make high speed coextrusion lamination molding possible. SOLUTION: A method for producing a laminated body has a constitution wherein a resin layer consisting of 4-methyl-1-pentene polymer is used as the surface layer and a resin compsn. of 4-methyl-1-pentene polymer and a high pressure low density polyethylene is used as an intermediate layer and they are laminated on a base material. In this case, as the 4-methyl-1-pentene polymer comprising the surface layer, a polymer with a melt flow rate(MFR) of 1-400g/10min and a contact angle as a polymer resin layer with water of at least 102 degree is used and as a resin compsn. comprising the intermediate layer, a compsn. of 4-methyl-1-pentene polymer and a high pressure low density polyethylene with an MFR of 0.1-100g/10min with a wt. compsn. ratio of 70/30-95/5 is used and they are coextrusion-laminated on the base material. |
