The present invention discloses a weld seam 80 between two edges between two laminates 1a and 1b, each laminate comprising a waterproof functional layer 50 and a fabric layer 30. The fabric layer 30 includes a first component and a second component, the first component being stable to the first temperature, and the second component may be melted at the second temperature. The seam 80 is formed by the molten second component and the unmelted first component of the fabric layer of each laminate, and the edges are substantially in an edge to edge butt joint orientation relationship. In this case, a waterproof seam of very small size is made. |
