Cross-directional extendible films having high breathability and low outer dampness

摘要: A breathable, substantially liquid impermeable microporous film and laminate are provided for use in a wide variety of personal care garments protective garments. The film, or containing the is extendible cross-direction to stretched width which at least 25% greater than an original, unstretched width. have first water vapor transmission rate about 500 grams/m 2 -24 hours average pore aspect ratio 4.0 coinciding with second 3.5 less, higher rate, When by 25%. upon stretching provides less backsheet dampness despite increase breathability.
