EASILY TEARABLE PACKAGING BAG

摘要

PROBLEM TO BE SOLVED: To simply draw out a damaged tape by laminating polyethylene resin layers each having a specific density on both side surface of a layer made of ionomer resin, thereby manually tearing it in the lateral and the longitudinal directions. SOLUTION: The easily tearable package uses as its packaging material a transparent multilayer film 2 obtained by laminating polyethylene layers 11 each having a density of 0.930 or less on both side surfaces of a layer 12 made of ionomer resin. The film 2 is obtained by laminating polyethylene films each having satisfactory tearability in the flowing direction (MD) of the film on front and rear surfaces of the film 12 so that the multilayer film has tearable properties in the MD. Particularly, the multilayer film is oriented by 1.05 to 1.30 times in the MD, thereby further upgrading the tearability in the MD. A layer constitution of the film 2 is formed so that a thickness ratio of the layer 11 to the layer 12 is (2:1) to (1:2) and a difference of the thicknesses of the polyethylene layers of both the surfaces falls within±10%.
