Abstract: Embodiments of a polyethylene composition are provided, which may include a first polyethylene fraction comprising at least one peak in a temperature range of from 40 C to 75 C in an elution profile via improved comonomer composition distribution (iCCD) analysis method, where a first polyethylene area fraction is an area in the elution profile from 40 C to 75 C, and where the first polyethylene fraction area comprises from 45% to 65% of the total area of the elution profile; and a second polyethylene fraction comprising at least one peak in a temperature range of from 85 C to 110 C in the elution profile, where a second polyethylene area fraction is an area in the elution profile from 85 C to 110 C, and where the second polyethylene fraction area comprises from 15% to 35% of the total area of the elution profile, wherein the polyethylene composition has a density of 0.905 g/cm3 to 0.918 g/cm3, a melt index (I2) of 0.7 g/10 minutes to 3.5 g/10 minutes, and wherein the composition has a melt index ratio (I10/I2) that meets the following equation: I10/I2
