Abstract:
The instant invention provides a polyethylene blend-composition suitable for blown films, and films made therefrom. The polyethylene blend-composition suitable for blown films comprises the melt blending product of: (a) from 0.5 to 4 percent by weight of a low density polyethylene having a density in the range of from 0.915 to 0.935 g/cm3, and a melt index (I2) in the range of from greater than 0.8 to less than or equal to 5 g/10 minutes, and a molecular weight distribution (Mw/Mn) in the range of from 6 to 10; (b) 90 percent or greater by weight of an ethylene/α-olefin interpolymer composition, wherein ethylene/α-olefin interpolymer composition has a Comonomer Distribution Constant (CDC) in the range of from 75 to 200, a vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of the ethylene/α-olefin interpolymer composition; a zero shear viscosity ratio (ZSVR) in the range from 2 to 20; a density in the range of from 0.903 to 0.950 g/cm3, a melt index (I2) in a range of from 0.1 to 5 g/10 minutes, a molecular weight distribution (Mw/Mn) in the range of from 1.8 to 3.5; (c) optionally a hydrotalcite based neutralizing agent; (d) optionally one or more nucleating agents; (e) and optionally one or more antioxidants.
