PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition having small neck-in and high spreadability and excellent in extrusion lamination workability, and to provide a laminate excellent in transparency and see-through property of contents.SOLUTION: There are provide a resin composition containing 3 to 99 wt.% of a propylene based polymer (X) containing ethylene and/or 1-butene as a monomer with 10.0 mol% or less as total amount and having a rate of strain hardening (λmax) measured by an elongational viscosity of 1.1 or more, and 1 to 97 wt.% of a polypropylene and/or propylene random copolymer (Y) having MFR of 1 to 50 g/10 min. or a polypropylene-based resin composition for extrusion lamination containing 3 to 99 wt.% of the propylene based polymer (X) containing ethylene and/or 1-butene as a comonomer with 10.0 mol% or less as total amount, and 1 to 97 wt.% of the polypropylene and/or propylene random copolymer (Y) having MFR of 1 to 50 g/10 min., and having a rate of strain hardening (λmax) measured by an elongational viscosity of 1.1 or more. |
