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 according to the present invention 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/cm, and a melt index (I) in the range of from greater than 0.8 to less than or equal to 5 g/10 minutes, and a molecular weight distribution (M/M) in the range of from 6 to 10; (b) 90 percent or greater by weight of a linear low density polyethylene composition has a density in the range of 0.900 to 0.935 g/cm, a molecular weight distribution (M/M) in the range of 1.5 to 4.5, a melt index (I) in the range of 0.1 to 5 g/10 minutes, a molecular weight distribution (M/M) in the range of less than 3, vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of said composition, and a zero shear viscosity ratio (ZSVR) in the range from 1 to less than 2; (c) optionally a hydrotalcite based neutralizing agent; (d) optionally one or more nucleating agents; (e) and optionally one or more antioxidants.
