Abstract: The present disclosure relates to polyethylene blends, films thereof, and methods thereof. In at least one embodiment, a polymer blend includes a first polyethylene having a density of about 0.94 g/cm3 to about 0.97 g/cm3 and a melt index of about 0.1 g/10 min to about 10 g/10 min. The blend includes a second polyethylene comprising at least 80 wt % ethylene derived-units. The second polyethylene has a density of about 0.918 g/cm3 to about 0.945 g/cm3, a number average molecular weight (Mn) of about 10,000 g/mol to about 20,000 g/mol, a weight-average molecular weight (Mw) of about 75,000 g/mol to about 300,000 g/mol, a melt index (2.16 kg) of about 0.1 g/10 min to about 5 g/10 min, a high load melt index (21.6 kg) of about 25 g/10 min to about 80 g/10 min, and a melt index ratio of about 10 to about 50.
