Abstract: A polymeric composition includes (i) a copolymer of ethylene and an alpha olefin comonomer, the copolymer having a density of 0.945 g/cc to 0.960 g/cc, (ii) an ethylene-based polymer, and (iii) polyethylene glycol. The combination of (i) and (ii) has a High Mw Comonomer Content of 3.2 wt % or greater based on a total weight of the combined (i) and (ii) over the weight average molecular weight range of 105 g/mol to 105.5 g/mol as measured by GPC, wherein 15 wt % or greater of the total weight of the polymeric composition is the combined (i) and (ii) having a molecular weight in the range of 105 g/mol to 105.5 g/mol as measured by GPC, wherein the polymeric composition has a Relevant Comonomer Content of 0.6 wt % or greater and wherein the polymeric composition has a density of 0.945 g/cc or greater as measured according to ASTM D792.
