POLYETHYLENE BLEND COMPOSITION SUITABLE FOR BLOWN FILM METHOD OF PRODUCING THE SAME AND FILMS MADE THEREFROM

摘要

The present invention provides a polyethylene blend composition suitable for a blown film, a process for producing the same, and a film produced therefrom. (A) a density in the range of 0.915 to 0.935 g / cm 3 , and a melt index in the range of from greater than 0.8 to 5 g / 10 min₂), And a molecular weight distribution (M_w/ M_n), 4% or less by weight of low density polyethylene (LDPE); (b) a density in the range of 0.917 to 0.950 g / cm 3 , and a melt index I₂) 90% by weight or more of heterogeneous linear low density polyethylene (hLLDPE); (c) optionally a hydrotalcite-based neutralizing agent; (d) optionally one or more nucleating agents; And (e) optionally, a melt compounded product of one or more antioxidants. When the polyethylene blend composition is formed into a film through a blown film process, the output rate is improved by 6% or more with respect to similar linear low density polyethylene.
