A description is given of a sealing slide fastener (10), comprising two tapes (1, 2) of elastic material with their edges (1b, 2b) facing each other, which are pressed against each other by the coupling of two sets of aligned teeth (3, 4) caused by the passage of a closing slider (8), in which at least the outer layers (1e, 2e) of the said two tapes (1, 2) and the said teeth (3, 4) are made from materials which can be welded together chemically. |
