Abstract
Disclosed is a laminate and absorbent articles made from the laminate where it can be used as an outer cover. In one embodiment, the laminate includes: a liquid-impermeable first layer having a first surface, a second layer having an interior surface adjacent the first surface and an exterior surface, at least a portion of the interior surface is joined to the first surface by an adhesive applied to the exterior surface, and the adhesive having a first bond peel strength of about 1 g/mm or greater. In another embodiment, the laminate induces: a liquid-impermeable first layer having a first surface, a nonwoven second layer having an interior surface adjacent the first surface and an exterior surface, at least a portion of the interior surface is joined to the first surface by first bonds having a first bond peel strength about 1 g/mm or greater, and at least a portion of the interior surface is joined to the first surface by second bonds having a second bond peel strength about 3 g/mm or less.
