Abstract: The present invention relates to a polymer composition comprising a linear low-density polyethylene produced in the presence of a single-site catalyst system and 0.01-2.00% by weight of a nucleating agent, the linear low-density polyethylene having a density as determined according to ISO 1183-1 (2012), method A of >900 kg/m3and ≤940 kg/m3, wherein films produced using the polymer composition have a total defected area of ≤50 ppm of surface, the total defected area being the fraction of surface area of the film accounted for by gels having an equivalent diameter of >50 μm. Such polymer compositions are suitable for the production of films having a low oxygen transmission rate and a low water vapour transmission rate.
