  • Publication number: 20040224596
    Abstract: A breathable barrier material having a first nonwoven layer and a first microporous film bonded together to form a composite laminate. A second microporous film and a second nonwoven layer are bonded to the composite laminate and second film to form the barrier material such that the films are disposed between the nonwoven layers. The composite laminate is bonded to the second film and second nonwoven layer thereby creating bond points in the material and void spaces between the first and second films. The void spaces between films may enhance liquid and viral barrier properties in the barrier material by creating a boundary that minimizes passage of liquids and/or viral components through the barrier material.
