A multiple layer hand-grip reinforcement for thermoplastic draw tape handles for thermoplastic bags and method of making the same is disclosed. The hand-grip reinforcement is produced by slitting a thermoplastic tape longitudinally with an undulating pattern to divide the tape into a pair of draw tapes each having alternating wide and narrow sections. 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. The folded tapes are inserted into each hem of a draw tape bag with the multiple layer tape section aligned with a central cut out opening intermediate the ends of the hem and the ends of each draw tape are secured to the ends of the respective hems so that when the multiple layer tape section is gripped and pulled through the cut out opening in the hems to draw closed the open top of the bag the multiple layer hand-grip reinforcement minimizes the discomfort caused by roping at the hand area while the bag is under load.

Multiple layer hand-grip reinforcement for thermoplastic draw tape

A hand-grip for thermoplastic draw tape handles for thermoplastic bags and method of making the same is disclosed. The hand-grip is produced by perforating each hem of the thermoplastic bag at a center section thereof with a substantially U-shaped perforation extending from the mouth of the bag to a location below the bottom of the hem whereby the center section of each hem is separable from the bag along the U-shaped perforation to provide a hand-grip surrounding each draw tape when the bag is lifted by the draw tapes.

Hand-grip for thermoplastic draw tape handles for thermoplastic bags

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. The ends of the draw tape at the unpadded tape sections are secured to the ends of the respective hems so that when the padded tape section is gripped and pulled through the cut out openings in the hems to draw closed the open top of the bag, the padded hand-grip reinforcement minimizes the discomfort caused by roping at the hand area while the bag is under load. In a preferred form of the invention the padding material comprises a curable foam which is cured by ultraviolet light.
