PROBLEM TO BE SOLVED: To provide a foamed laminate which shows excellent heat-insulating properties and foam appearance and is excellent in economical efficiency.SOLUTION: There is provided a foamed laminate which contains at least an (A) layer, a paper substrate and a (B) layer and satisfies the following (i) to (III). The (A) layer is a foam layer and is formed of a high-pressure method low-density polyethylene (a) having a density of 910 to 930 kg/mand the (B) layer is formed of a polyethylene-based resin (b) having a density of 935 to 970 kg/m: (i) a ratio of the thickness (μm) of the (A) layer after foaming to the basis weight (g/m) of the paper substrate is 2.8 or more and 7.0 or less; (ii) the basis weight (g/m) of the paper substrate is 160 or more and 400 or less; (iii) the moisture content of the paper substrate after laminating the high-pressure method low-density polyethylene (a) and the polyethylene-based resin (b) is 22 g/mor more and 40 g/mor less. |
