摘要：
According to one or more embodiments, a polyethylene composition that is suitable for packaging applications may include a first polyethylene fraction and a second polyethylene fraction. The first polyethylene fraction may have a single peak in a temperature range of 45 ̊C to 87 ̊C in an elution profile via the improved comonomer composition distribution (iCCD) analysis method. The second polyethylene fraction may have a single peak in a temperature range of 95 ̊C to 120 ̊C in the elution profile via iCCD analysis. Additional embodiments disclosed herein include articles and films comprising the polyethylene compositions described herein.
