Patent ID: 8703871

Claim:
A polyolefin resin composition comprising: not less than 1% by weight and less than 80% by weight of a propylene polymer (I) defined below, not less than 1% by weight and less than 80% by weight of a propylene copolymer (II) defined below and/or an ethylene copolymer (III) defined below, and more than 20% by weight and not more than 98% by weight of an ethylene polymer (IV) defined below, wherein a ratio of the content of the ethylene polymer (IV) to the sum total of the contents of the propylene copolymer (II) and the ethylene copolymer (III) is within a range of from 0.25 to 98 with the proviso that the combined amount of the propylene polymer (I), the propylene copolymer (II), the ethylene copolymer (III) and the ethylene polymer (IV) is taken as 100% by weight, wherein the propylene polymer (I) is a propylene homopolymer or a copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and α-olefins having 4 to 10 carbon atoms, the copolymer having more than 0% by weight and less than 20% by weight of structural units derived from the at least one comonomer, with the proviso that the overall weight of the polymer (I) is taken as 100% by weight, wherein the propylene copolymer (II) is a copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and α-olefins having 4 to 10 carbon atoms, the copolymer having 20 to 80% by weight of structural units derived from the comonomer with the proviso that the overall weight of the copolymer (II) is taken as 100% by weight, wherein the ethylene copolymer (III) is a copolymer of ethylene and an α-olefin having 4 to 10 carbon atoms, the copolymer having a density of less than 940 kg/m 3 , and wherein the ethylene polymer (IV) is a polyethylene having a melt flow rate measured at 190° C. and a load of 21.18 N of 12 to 100 g/10 minutes and a density of 940 to 970 kg/m 3 , excluding an ethylene-propylene copolymer.
