Abstract: According to one or more embodiments, a polyethylene composition, which may include a first polyethylene fraction area defined by an area in an elution profile via iCCD analysis method in a temperature range of 45° C. to 90° C.; a first peak in the temperature range of 45° C. to 90° C. in the elution profile; a second polyethylene fraction area defined by an area in the elution profile in a temperature range of 90° C. to 120° C.; a second peak in the temperature range of 90° C. to 120° C. in the elution profile; and a local minimum in a temperature range of from 80 C to 95° C. in the elution profile. The polyethylene composition may have a density of 0.924 g/cm3 to 0.936 g/cm3 and a melt index (I2) of 0.5 g/10 minutes to 1.2 g/10 minutes. A ratio of the first polyethylene fraction area to the second polyethylene fraction area may be 2.0 to 4.0.
