Abstract
Polyethylene compositions are disclosed that may have a density of 0.910 g/cmto 0.924 g/cmand a melt index (I) In of 0.1 g/10 minutes to 0.5 g/10 minutes and include a first polyethylene fraction area in the temperature range from 45° C. to 80° C. of an elution profile via improved comonomer composition distribution (iCCD) analysis method; a second polyethylene fraction area in the temperature range from 80° C. to 95° C. of the elution profile, and a third polyethylene fraction area in the temperature range from 95° C. to 110° C. of the elution profile. The second polyethylene fraction area may include at least 5% of the total area of the elution profile. The third polyethylene fraction area may include at least 25% of the total area of the elution profile. A ratio of the first polyethylene fraction area to the second polyethylene fraction area may be from 6 to 15.
