<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a foam laminate capable of exhibiting excellent heat insulation properties from an initial stage of heating.SOLUTION: A method is for manufacturing a foam laminate at least including a layer (A)/a paper substrate/a layer (B), laminated in this order. The method for manufacturing a foam laminate at least includes the following processes (i)-(iii): (i) a process of applying a solution including a foaming agent on one or both sides of the paper substrate; (ii) a process of laminating onto the paper substrate, a polyethylene-based resin (a) whose density is 935-970 kg/m, as the layer (A), and as the layer (B), a high-pressure-processed low density polyethylene (b) whose density is 910-930 kg/m; and (iii) applying heat treatment to a laminate including the polyethylene-based resin (a)/the paper substrate/the high-pressure-processed low density polyethylene (b), to foam the high-pressure-processed low density polyethylene (b).</p> |
