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 6 percent by weight of a bimodal linear low density polyethylene having a density in the range of from 0.935 to 0.970 g/cm3, and a melt index (I2) in the range of from 0.3 to 5 g/10 minutes; (b) 90 percent or greater by weight of a monomodal linear low density polyethylene having a density in the range of from 0.910 to 0.950 g/cm3, and a melt index (I2) in the range of from 0.1 to less than or equal to 5 g/10 minutes; (c) optionally 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; (d) optionally a hydrotalcite based neutralizing agent; (e) optionally one or more nucleating agents; and (f) optionally one or more antioxidants.
