Abstract:
The instant invention provides a polyolefin composition suitable for packaging applications, films, multilayer structures and packaging devices made therefrom. The polyolefin composition according to the present invention comprises: an ethylene/α-olefin interpolymer composition comprising (a) from 50 to 75 percent by weight of a first ethylene/α-olefin copolymer fraction having a density in the range of 0.894 to 0.908 g/cm3, a melt index (I2) in the range of from 0.2 to 1 g/10 minutes, and (b) from 25 to 50 percent by weight of a second ethylene/α-olefin copolymer fraction, and wherein said ethylene/α-olefin interpolymer composition has a density in the range of 0.910 to 0.924 g/cm3, a melt index (I2) in the range of from 0.5 to 2 g/10 minutes, a zero shear viscosity ratio (ZSVR) in the range of from 1.15 to 2.5, a molecular weight distribution, expressed as the ratio of the weight average molecular weight to number average molecular weight (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 6 to 43.
