The wide section has a dimension at least twice as great as the intervening narrow section. The wide section is folded over along a longitudinal crease line to provide a multiple layer tape section intermediate two single layer tape sections.

  • Patent number: 4813792
    Abstract: A hand-grip for thermoplastic draw tape handles for thermoplastic bags and method of making the same is disclosed.

  • Patent number: 4813793
    Abstract: A padded reinforced handle for thermoplastic draw tape bags and method of making the same is disclosed. The padded hand-grip reinforcement for the draw tape handle is produced by folding a thermoplastic draw tape longitudinally into a V-shaped cross-section and inserting a predetermined quantity of padding material into the V-shaped cross section of the tape to provide a padded tape area at predetermined spaced intervals corresponding to the width of the draw tape bag. The padded tape section has a length adequate to provide a padded hand-grip reinforcement. The padded tapes are inserted into the hems of the draw tape bag with the padded tape section aligned with a central cut out opening intermediate the ends of the hems.
