A slide fastener for use on an object such as a bag of paper or nonwoven fabric has a pair of stringer tapes each having a tape of paper or nonwoven fabric coated on one surface with a film of thermoplastic synthetic resin. Each stringer tape is folded back on itself along a longitudinal fold, providing a folded longitudinal strip with the film facing outwardly. A row of coupling elements is attached, such as by sewing, to each stringer tape along the folded strip. The film reinforces the tape of paper or nonwoven fabric, can easily be bonded to the object upon heating, and provides smooth surfaces for allowing a slider to slide smoothly thereon. |
