摘要： Provided is a polyethylene resin film exhibiting more improved transparency while exhibiting excellent processability and mechanical properties. The polyethylene resin film has a density of 0.910 g/cm 3 to 0.930 g/cm 3 , includes a first polyethylene resin and a second polyethylene resin at a weight ratio of 6 : 4 to 8 : 2, wherein the first and second polyethylene resins have different MFRR (21.6/2.16) values, the MFRR (21.6/2.16) value obtained by dividing a melt flow rate (MFR 21.6 ) measured at a temperature of 230°C under a load of 21.6 kg in accordance with ISO 1133 by a melt flow rate (MFR 2.16 ) measured at a temperature of 230°C under a load of 2.16 kg in accordance with ISO 1133, and the first polyolefin resin has an MFRR (21.6/2.16) value of 27 to 40, and the second polyolefin resin has an MFRR (21.6/2.16) value of 15 to 23, and has a haze of 10% or less at a thickness of 90 µm to 110 µm.
