<p>PROBLEM TO BE SOLVED: To provide a foamable laminate which is produced with excellent moldability, is heated to obtain a foamed cell (a foamed layer) having satisfactory height and excellent external appearance, and is obtained in the productivity higher than usual.SOLUTION: A method for producing the foamable laminate comprises a step of forming a foamable polyethylene resin layer (I) on at least one surface of a paper-based base material. The polyethylene resin layer (I) comprises a polyethylene resin composition (C) obtained by mixing 50-98 wt.% of a low density polyethylene resin (A), which is obtained by a high-pressure radical polymerization method and satisfies specific MFR, with 2-50 wt.% of another low density polyethylene resin (B), which is obtained by the high-pressure radical polymerization method and satisfies specific MFR. The foamable laminate is produced in such a condition that the extrusion lamination molding speed is 50 m/min or higher.</p> |
