Provided is a polyethylene film that is more excellent in blocking in unwinding the film in the film roll state, and more excellent in blocking between sealants after lamination with a base material, and also having transparency and excellent heat sealing property even at low temperatures. A polyethylene film wherein in at least either face, a ratio between an arithmetic mean inclination angle in a machine direction of film (R&#x394;a (MD) [&#xb0;]), and an arithmetic mean inclination angle in a direction perpendicular to the machine direction (R&#x394;a (TD) [&#xb0;]) satisfies the following formula (1):1.2&#x2264;(TD)/(MD)&#x2264;3.6&#x2003;&#x2003;(1)

Polyethylene film

Provided is a polyethylene film showing more excellent blocking resistance in unwinding from the film roll state and more excellent blocking resistance between sealants after lamination with a base material, and having transparency and excellent heat sealing property even at low temperatures. A polyethylene film wherein in at least either face, a ratio between an arithmetic mean roughness in a machine direction of film (Ra(MD)), and an arithmetic mean roughness in a direction perpendicular to the machine direction (Ra(TD)) satisfies the following formula (1):1.2&#x2264;()/()&#x2264;3.6&#x2003;&#x2003;(1) (Ra(MD): arithmetic mean roughness [&#x3bc;m] measured in the machine direction of film, and Ra(TD): arithmetic mean roughness [&#x3bc;m] measured in the direction perpendicular to the machine direction of film).
