  • Patent number: 10556409
    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 [?m] measured in the machine direction of film, and Ra(TD): arithmetic mean roughness [?m] measured in the direction perpendicular to the machine direction of film).
    Type: Grant

  • Patent number: 10556407
    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 (R?a (MD) [°]), and an arithmetic mean inclination angle in a direction perpendicular to the machine direction (R?a (TD) [°]) satisfies the following formula (1): 1.2?R?a(TD)/R?a(MD)?3.6??(1) (R?a (MD): arithmetic mean inclination angle measured in the machine direction of film, and R?a (TD): arithmetic mean inclination angle measured in the direction perpendicular to the machine direction of film).
