A fluid-tight slide fastener (10) is disclosed. The fluid-tight slide fastener (10) comprises a pair of tapes (12). Each tape (12) has a layered structure comprising an inner reinforcing textile material layer (14) enveloped in a fluid barrier layer (16), where the fluid barrier layer (16) is made of a thermoplastic elastomer material (TPE). Each tape (12) exhibits a row (20) of aligned teeth (21) made of a thermoplastic material on at least a portion of one of the long sides (13a). The rows (20) of aligned teeth (21) of the pair of tapes (12) face each other and are associated to opposite stops (24, 26). A slider (22) is slidable between the opposite stops (24,26) for engaging in a fluid-tight way or disengaging the aligned teeth (21) respectively. The textile material for the inner reinforcing layer (14) is chosen among polyester (PE), preferably PET, polyamide (PA) and their blends or copolymers. The thermoplastic elastomer material (TPE) for the fluid barrier layer (16) is chosen between thermoplastic elastomer polyurethane (TPE-U) and thermoplastic elastomer polyester (TPE-E), and the thermoplastic material for the teeth (21) is chosen among polybutylene terephthalate (PBT), poly (acrylonitrile butadiene styrene) (ABS), polyamide (PA) and their blends or copolymers. |
