Abstract: A polypropylene composition includes (A) a polypropylene, (B1) a first copolymer of ethylene and α-olefin having a density of 0.891 to 0.912 g/cm3, and (B2) a second copolymer of ethylene and α-olefin having a density in the range of 0.859 to 0.881 g/cm3, wherein the amount of (A) the polypropylene is in the range from 71 to 87 wt % based on the total amount of the polymer composition, and wherein the ratio between the amount of the (B2) second copolymer of ethylene and α-olefin and the amount of the (B1) first copolymer of ethylene and α-olefin is in the range from 3.8 to 1.0. The polypropylene composition has improved stress whitening resistance. A battery case including the polypropylene composition is also disclosed.
