<p>PROBLEM TO BE SOLVED: To tear off surface and rear sheets of an opening of a bag body straight for neatly unsealing and to insure easy repetitive unsealing and sealing by cutting perforations oppositely in parallel to a fastener body of female-male fitting integrally molded with a face of a thin strip base piece on a side positioned at a mouth of the bag body. SOLUTION: A fastener seal 7 comprises a pair of female and male fastener bodies 5, 6 fitting in recess and protrusion which are integrally formed with thin strip base pieces 3, 4, wherein the base pieces 3, 4 are formed to be wide, and perforations 11, 12 are cut on their faces over a full length. The perforations 11, 12 are formed to be straight and opposite so that the base pieces 3, 4 can be easily separated by tearing and ways for tearing can be easily made on sheets 1, 2 of a bag body. Therefore, when a mouth end rim C to be a top seal is to be cut off from the bag body 1 for unsealing, the surface and rear sheets 1, 2 can be torn off straight together with the perforations 11, 12 while being guided by the perforations 11, 12 of the base pieces 3, 4 from a notch.</p> |
