Blown films comprising bimodal ethylene-based polymers having high molecular weight high density fractions

A blown film having a bimodal ethylene-based polymer including a high density fraction (HDF) from 3.0% to 25.0%, an I10/I2 ratio from 5.5 to 7.5, a short chain branching distribution (SCBD) less than or equal to 10 DEG C, a zero shear viscosity ratio from 1.0 to 2.5, a density from 0.902 g/cc to 0.9...
