1. A polyethylene copolymer comprising:
a copolymer of ethylene and 1-hexene, wherein the polyethylene copolymer has: (i) a molar mass distribution width Mw/Mn from 7 to 15, (ii) a density from 0.942 to 0.946 g/cm3, (iii) a weight average molar mass Mw from 20,000 g/mol to 500,000 g/mol, (iv) from 0.7 to 20 CH3/1000 carbon atoms as determined by NMR, (v) a high load melt index from 115 to 220 g/10 min, and (vi) a melt flow rate (MI, at 2.16 kg) from 3.5 to 4.5 g/10 min.
