    摘要: The present invention relates to a sheet or board like multiple layers laminated polyolefin foam having a plurality of polyolefin layers laminated on at least one side of a polyolefin foam by a coextrusion method. More specifically, the present invention relates to said multiple layers laminated polyolefin foam, wherein the thickness of the outermost layer constituting the plurality of polyolefin layers is 5 to 80 μm, and the density d (g/L) of the polyolefin foam, the melt flow rate X (g/10 min) of the polyolefin constituting the innermost layer among the plurality of polyolefin layers, and the thickness Y (μm) of the innermost layer of the multiple polyolefin layers satisfy the following relationships (1) to (4). Y≦0.29dX  (1) 5≦X≦40  (2) 70≦Y≦300  (3) 100≦d≦300  (4)
