Patent ID: 8900109

Claim:
A process of making a plastic bag or pouch comprising the steps of: running a pair of plastic webs juxtaposed one spaced above another; introducing a tape into the space between said webs adjacent one side thereof, said tape being comprised of an elongated plastic film having a top surface and a bottom surface, a pair of elongated attachment lanes sealed to said film on the top surface, said lanes composed of complementary fastening elements to effect an attachable-detachable closure, said lanes extending parallel and being spaced apart, a single perforation line formed in said film midway between said lanes, and said film on the top surface defining a flange on one side of said lanes; folding said tape along the perforation line by pulling through a slot so that the lanes engage in registry inside the folded tape with the flange extending therefrom with the bottom surface being exposed; sealing the bottom surface of the folded tape underlying the flange of said tape to one of said plastic webs adjacent said one side without sealing the lane adjacent the flange to said one side; sealing the bottom surface of the folded tape underlying the lane of said tape remote from said flange to the other plastic web adjacent said one side; cutting the tape along the single perforation line to separate the two lanes; disengaging the lanes to separate the webs; and processing the plastic webs into bags or pouches having a mouth with the lanes of said tape sealed to opposite sides of the mouth inside the bag or pouch to provide a closure for the bag or pouch.
