Abstract
The instant invention provides a polyethylene blend composition suitable for blown film, method of producing the same, and films made therefrom. The polyethylene blend composition suitable for blown film according to the present invention comprises the melt blending product of: (a) less than or equal to 4 percent by weight of a low density polyethylene (LDPE) 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 heterogenous linear low density polyethylene (hLLDPE) having a density in the range of from 0.917 to 0.950 g/cm, and a melt index (I) in the range of from 0.1 to less than or equal to 5 g/10 minutes; (c) optionally a hydrotalcite based neutralizing agent; (d) optionally one or more nucleating agents; and (e) optionally one or more antioxidants. When the polyethylene blend-composition is formed into a film via blown film process, the output rate is improved at least 6 percent relative to a similar linear low density polyethylene.
