摘要
An easy open and reclosable bag has flexible sheet walls sealed together to form a pouch. A separable reclosure tie is located adjacent one of those seals. The reclosure tie is composed of extensions of the bag walls which have an integral channel-shaped molding spaced from that seal. A line of specially shaped, closely spaced apart perforations through the bag walls extends between the molding and the one seal to permit the reclosure tie to be separated from the pouch-defining walls of the bag. Apparatus for making the easy open and reclosable bag is also disclosed.
