Abstract
A breathable, substantially liquid impermeable film and laminate are provided for use in a wide variety of personal care garments and protective garments. The film, and laminate containing the film, are extendible in a cross-direction to a stretched width which is at least 25% greater than an original, unstretched width. The film and laminate have a first water vapor transmission rate of at least about 500 grams/m -24 hours coinciding with the unstretched width. The film and laminate have a much higher second water vapor transmission rate which is at least about 225% of the first water vapor transmission rate, and not less than about 4000 grams/m -24 hours, coinciding with a stretched width that is only 25% greater than the stretched width.
