Claim:
1. A method of manufacturing a portion of a slide fastener, the method comprising: providing a first tape having a first edge; providing the first tape with a row of coupling elements along the first edge of the first tape, the coupling elements being configured to interdigitate with a further row of coupling elements; attaching a first layer of a fluid resistant material to the first tape; attaching an extending layer of a fluid resistant material to the first layer, the extending layer forming an extension member comprising a first overhang portion which extends beyond a second edge of the first tape opposite the first edge of the first tape, wherein the first layer of the fluid resistant material is attached to the first tape and the extending layer is attached to the first layer such that there is no fluid path through the first layer and/or the extending layer to the first tape, wherein the first layer of the fluid resistant material is a layer of thermoplastic material which is extruded onto the first tape and the extending layer of the fluid resistant material is a thermoplastic material which is extruded onto the first layer at least at a position close to the second edge of the first tape, and wherein a back surface of the first tape is substantially flush with a back surface of the extending layer.
