  • Publication number: 20050173053
    Abstract: A reclosable packaging bag comprises a main bag body having an opening portion and at least one heat-sealed portion; and a linear fastener provided on the opening portion of the main bag body. The linear fastener is provided along the opening portion of the main bag body by an insert injection molding so as not to extend to the heat-sealed portions. A method for manufacturing the bag comprises the three steps. First, the first and second linear fastening members are formed on a prescribed position of a sheet of film material by an insert injection molding so as to be spaced from each other. These fastening members are engageable with each other to form a linear fastener. Second, the sheet of film material is folded in two so that the fastening members can engage with each other. Third, each of opposite portions of the sheet of film material thus folded is heat-sealed to form side heat-sealed portions.
