Abstract
PURPOSE:To certainly open a bag in a desired direction by the force of an arm or hand, by using the part, where the lateral orientation direction of a molecule almost crosses the length direction of a film at a right angle, of the film wherein lateral stretching magnification is larger than longitudinal stretching magnification as a film material. CONSTITUTION:A seal part 2 is divided in a grip piece providing part 3 and a pour port providing part 4 in the longitudinal direction and a broken line like perforation 6 is provided to the grip piece providing part 3 in almost parallel to the end edge line 5 of the mouth part thereof and the pour port providing part 4 is sealed so as to become shallower than the grip piece providing part 3. As a result, the extension line part of the perforation 6 is left without being sealed to provide a pour port 7. When end part of the grip piece providing part 3 is pulled along the perforation, said grip piece providing part 3 can be broken by the force of a hand because the perforation is applied. When the grip piece providing part is broken up to the tearing start part 8 of the terminal part of the perforation, there is no perforation thereafter and tearing is not propagated on and after. When the grip piece providing part is further pulled, force is concentrated to the tearing start part 8 and the pour port 7 can be opened.
