Abstract
A zipper tape is provided which can freely be used regardless of whether the zipper tape is made from a polypropylene-based resin or a polyethylene-based resin and also on which letters can be printed or any color can be given thereto. A method of producing the zipper tape with high productivity by means of extruding male strips and female strips in rows in a batch is provided. The zipper tape with the mating section formed thereon has a three-layered structure. The male strips and female strip for forming a mating section together are extruded from a miscellaneous extrusion molding machine onto a surface of the thermally fused film for forming a mating section in rows in the state where adjoining male and female strips form pairs respectively and are thermally fused and bonded to the base tape.
