Disclosed herein are various processes, including a process for producing a film, comprising (including) forming a film from a blended polyolefin composition at a line speed of at least 170 feet per minute, wherein the blended polyolefin composition comprises: (a) a bimodal polyethylene component that includes a high molecular weight polyethylene component having a high average molecular weight (MW<SUB>HMW</SUB>) and a low molecular weight polyethylene component having a low average molecular weight (MW<SUB>LMW</SUB>), wherein the ratio of the high average molecular weight to the low average molecular weight (MW<SUB>HMW</SUB>:MW<SUB>LMW</SUB>) is 20 or more wherein the high and low molecular weight polyethylene components of the bimodal polyethylene component are formed in a single reactor; and (b) a unimodal polyethylene component that occupies more than 15 wt % of the composition.
