Patent ID: 8431634

Claim:
A polypropylene resin composition comprising: 100 parts by weight of a resin composition, which contains 51 to 99% by weight of a propylene polymer and 1 to 49% by weight of an ethylene polymer, wherein the ethylene polymer is an ethylene-α-olefin copolymer containing 51 to 99% by weight of an ethylene unit and 1 to 49% by weight of an α-olefin unit having 4 to 10 carbon atoms, and having a density of 0.85 to 0.93 g/cm 3 , and a melt flow rate of 0.5 to 50 g/10 minutes measured at 190° C. under a load of 2.16 kg, provided that the total of the ethylene unit and the α-olefin unit is 100% by weight, provided that the total of the propylene polymer and the ethylene polymer is 100% by weight; and 0.001 to 0.5 part by weight of a metal salt represented by following formula (I), wherein R 1 to R 10 are independently of one another a hydrogen atom, an alkyl group having 1 to 9 carbon atoms, a hydroxyl group, an alkoxy group having 1 to 9 carbon atoms, an amino group, an alkylamine group having 1 to 9 carbon atoms, a halogen atom, a phenyl group, or a group represented by the formula, R—(R′—O) n —, R being an alkyl group having 1 to 3 carbon atoms, R′ being an alkylene group having 2 or 3 carbon atoms, and n being an integer of 1 to 4; any two alkyl groups of R 1 to R 10 may be linked to each other, thereby forming a carbon ring having 3 to 6 carbon atoms; and R 1 and R 2 have a trans or cis configuration with each other.
