The instant invention provides a polyolefin composition suitable for injection molding applications, and method of making such injection molded articles. The polyolefin composition suitable for injection molding applications comprises: an ethylene/α-olefin interpolymer composition comprising: (a) from 25 to 50 percent by weight of a first ethylene/α-olefin copolymer fraction having a density in the range of from 0.924 to 0.937 g/cm3, a melt index (I2) in the range of from 0.03 to 0.3 g/10 min, (b) from 50 to 75 percent by weight of a second ethylene homopolymer fraction having a density in the range of from greater than 0.960 g/cm3, a melt index (I2) in the range of from 100 to 180 g/10 minutes, wherein said ethylene/α-olefin interpolymer composition has a density in the range of from 0.950 to 0.958 g/cm3, a melt index (I2) in the range of from 1.0 g/10 min to 3.5 g/10 min, a zero shear viscosity ratio (ZSVR) in the range of from 1.01 to 2.5, a molecular weight distribution (Mw/Mn) in the range of from 2.0 to 4.0, and tan delta at 0.1 radian/second and 190° C. in the range of from 9 to 50.
