Abstract

Films and methods of forming films comprising first combining in a reactor olefins, a catalyst composition and an activator; wherein the activator is present from less than 50 wt % in a diluent by weight of the activator and diluent; followed by isolating a polyolefin having a density of from 0.940 to 0.980 g/cm3; and finally, extruding the polyolefin into a film having a gel count of less than 200 gels/m2.
