Abstract: The invention relates to linear low density polyethylene having a density in the range from about 900 kg/m3 to less than about 940 kg/m3 as determined using IS01872-2, having a molecular weight distribution (Mw/Mn) in the range from 2.5 to 3.5, having an area under the peak in the temperature range from 20 to 40° C. determined using an analytical temperature rising elution fractionation analysis using 1,2-dichlorobenzene and a heating rate of 1° C./min, wherein the area is in the range from 5 to 20% of the sum of the areas under all peaks determined with the analytical temperature rising elution fractionation analysis.
