PROBLEM TO BE SOLVED: To provide a laminate having excellent interlayer strength between a layer containing a 4-methyl-1-pentene based polymer and other synthetic resin layer.SOLUTION: There is provided a laminate which comprises: a substrate layer (A) having (a) 60 to 100 mole% of a structural unit (i) derived from 4-methyl-1-pentene and 0 to 40 mol% of a structural unit (ii) derived from ethylene and an α-olefin having 3 to 20 carbon atoms (provided that the total of (i) and (ii) is 100 mol%), (b) an MFR of 0.3 to 400 g/10 min as measured at 260°C under a load of 5 kgf, (c) a melting point of 100 to 260°C and (d) a density of 820 to 850 kg/m; and a synthetic resin layer (B), wherein the peeling rate (%)={(the peeled number)/(the total number)}×100 is 5% or less in the cross cut test.SELECTED DRAWING: None |
