  • Polypropylene-based resin composition and film
    Patent number: 9127133
    Abstract: A polypropylene-based resin composition comprising 61 to 85% by weight of a copolymer (X) of propylene, ?-olefin having 4 or more of carbon atoms and/or ethylene, in which a content of a constitutional unit derived from propylene is 86 to 97% by weight, a total of a content of a constitutional unit derived from ethylene and a content of a constitutional unit derived from ?-olefin having 4 or more of carbon atoms is 3 to 14% by weight, provided that a total of the content of a constitutional unit derived from propylene, the content of a constitutional unit derived from ethylene and the content of a constitutional unit derived from ?-olefin having 4 or more of carbon atoms is defined to be 100% by weight, 1 to 38% by weight of a copolymer (Y) of propylene and ?-olefin having 4 or more of carbon atoms, in which a melting point is 115° C.
