Abstract
A laminate web comprising a first web, a second web joined to the first web at a plurality of discrete bond sites; and a third material disposed between at least a portion of the first and second nonwovens. The third material is apertured in regions adjacent the bond sites, such that the first and second nonwoven webs are joined through the apertures. In one embodiment an apertured laminate web is disclosed, having a first extensible web having a first elongation to break, and a second extensible web joined to the first extensible web at a plurality of bond sites, the second extensible web having elongation to break. A third web material is disposed between the first and second nonwovens, the third web material having a third elongation to break which is less than both of the first or second elongations to break. In a further embodiment, an apertured laminate web is disclosed, having first and second extensible webs being joined at a plurality of discrete bond sites and a third material disposed between the first and second nonwoven webs. The first and second nonwoven webs are in fluid communication via the apertures and have distinct regions being differentiated by at least one pr…
