Abstract: The present disclosure relates to polyethylene compositions, articles (e.g., films) including such polyethylene compositions, and methods of making polyethylene compositions and articles (e.g., films) thereof. The polyethylene composition comprises 80 wt % or greater ethylene-derived units; has density within the range from 0.940 to 0.975 g/cm3; a melt index (MI) of 0.1 to 3.0 g/10 min (such as 0.5 g/10 min to 2.5 g/10 min); a high load melt index (HLMI) within the range from 60 g/10 min to 150 g/10 min; a melt index ratio (MIR, defined as HILMI/MI) greater than 50; and has a crossover frequency (COF) according to the following relationship: COF>−0.00015*(Mw)+80 (where COF is in rad/s and Mw is weight-average molecular weight in g/mol).
