ABSTRACT:
A breathable barrier laminate is disclosed having a first film layer comprising a microporous breathable barrier film; a second film layer comprising a breathable filled film which comprises about 50% to about 70% by weight filler and an amorphous polymer such as an elastomeric ethylene polymer having a density less than 0.89 g/cm.sup.3 ; and a third fibrous layer comprising a breathable outer layer, such as a nonwoven web of spunbonded fibers. The multiple layers can be thermally laminated wherein laminate has a peel strength in excess of 200 grams and a WVTR in excess of 300 g/m.sup.2 /day.
