Abstract:
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≤Ra(TD)/Ra(MD)≤3.6 (1) (Ra(MD): arithmetic mean roughness [μm] measured in the machine direction of film, and Ra(TD): arithmetic mean roughness [μm] measured in the direction perpendicular to the machine direction of film).
