Abstract
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 (RΔa (MD) [°]), and an arithmetic mean inclination angle in a direction perpendicular to the machine direction (RΔa (TD) [°]) satisfies the following formula (1):1.2≤(TD)/(MD)≤3.6  (1)
