Abstract
A breathable laminate has a liquid-resistant backing film layer having varied vapor permeability that includes breathable thinned localized regions and thicker non-breathable regions, wherein the film layer is co-extensively directly joined with a liquid- and vapor-permeable nonwoven fabric. The breathable laminate can have unidirectional air permeability. The present invention also relates to disposable apparel and absorbent products which incorporate the breathable laminate, and methods of making the breathable laminate.
