Abstract: The present invention relates to polyethylene compositions. In one aspect, a polyethylene composition comprises (1) a first polyethylene fraction having a single peak in a temperature range of 50° C. to 85° C. in an elution profile via iCCD analysis method, (2) a second polyethylene fraction having a single peak in a temperature range of 85° C. to 100° C. in the elution profile via iCCD analysis method, and (3) a third polyethylene fraction having a single peak in a temperature range of 100° C. to 120° C. in the elution profile via iCCD analysis method, wherein the first polyethylene area fraction comprises 25 to 50% of the total area of the elution profile, wherein the second polyethylene area fraction comprises 30 to 50% of the total area of the elution profile, and wherein the third polyethylene area fraction comprises 15 to 35% of the total area of the elution profile.
