  • Reclosable storage bag and method for making the same
    Patent number: 6086524
    Abstract: A storage bag and a method and apparatus for forming such a storage bag. The storage bag contains a reclosure tie formed as an integral marginal portion of the bag beyond an edge of the bag. The marginal portion includes overlying layers of bag material that form an elongated structure along an axis with first and second ends. A fused closure is formed in the marginal portion parallel to the axis and over a portion of the marginal portion spaced from one end thereof. This structure defines a tail and open loop that wrap around an opened bag thereby to close the bag in a positive fashion.

  • Apparatus for making easy open and reclosable bags
    Patent number: 4682976
    Abstract: 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.
