A welded web comprising a first edge of a web having at least one aperture overlapping a second edge of a web comprising thermoplastic material on an exposed surface along the second edge to form a region of contiguous contact between the first edge and the second edge, at least a portion of the thermoplastic material at least partially filling the aperture thereby bonding the first edge to the second edge. The web may be formed by a process comprising providing a web having a first edge, providing a web having a second edge, forming at least one aperture in at least the first edge, overlapping the first edge over the thermoplastic material on the exposed surface along the second edge whereby the thermoplastic material on the second edge at least covers the aperture to form a region of contiguous contact between the first edge and the second edge, raising the temperature at least in the region of contiguous contact adjacent the aperture whereby thermoplastic material from the second edge at least partially fills the aperture thereby bonding the first edge to the second edge.
