Document Type and Number:
Japanese Patent JP3982116
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a resin composition for extrusion lamination excellent in initial adhesion to a laminating substrate and further heat resistance thereof and especially suitable for providing a laminate comprising a propylene-based resin layer formed on the laminating substrate. SOLUTION: This resin composition for extrusion lamination is a resin composition comprising (A) a propylene-based resin modified with an unsaturated carboxylic acid or its derivative and having 0.01-20 wt.% content of the unsaturated carboxylic acid or its derivative unit and 100-10,000 g/10 min melt flow rate and (B) other olefinic polymers. The modified polypropylene-based resin (A) accounts for 0.1-30 wt.% ratio of the whole resin composition and the predominant amount of the other olefinic polymers (B) is (B-1) a polypropylene- based resin having >=95.0 wt.% propylene content and 0.5-50 g/10 min melt flow rate.
