Claims

[Claims for Utility Model Registration] (1) In a pouch that is made by heat-sealing the four sides of two film-like packaging materials with a sealant to retain the contents inside, the inner surface of one of the packaging members is planned to be torn. A tape material made of a uniaxially stretched film having tearability in one direction and formed wider than the opening width is adhered to the packaging member, and the tape material and this tape material are further adhered to the heat-sealed portions of both packaging members. 1. A pouch having a tear portion, characterized in that a notch equal to the opening width is cut across the pouch, and the pouch is heat-sealed except for the area around the notch. (2) A uniaxially stretched film with thermoplastic resin laminated on both sides is used as the tape material, and one of the thermoplastic resins can be firmly heat-sealed with a sealant that heat-seals the four sides of the two film-like packaging materials.
