<p>PROBLEM TO BE SOLVED: To provide a polypropylene resin composition having a small quantity of neck-in, high spreadability, and excellent high-speed extrusion lamination processability, and a laminate excellent in bag drop durability and impact resistance.SOLUTION: The polypropylene resin composition for extrusion lamination comprises: 3 to 50 wt.% of a polypropylene resin (X) having a branch structure and satisfying the following conditions for characteristics; and 97 to 50 wt.% of a propylene-ethylene block copolymer (Y). The conditions are: Mw/Mn is 3.0 to 10.0; a branch index g' at an absolute molecular weight Mabs of 1000000 is 0.30 or more and less than 1.00; and a melt tension (MT) satisfies either log(MT)≥-0.9×log(MFR)+0.7 or MT≥15.</p> |
