    摘要: A polymeric film extrusion die having a die body with a molten polymer inlet, a molten polymer exit, and forming a molten polymer conduit providing a fluid communication between the molten polymer inlet and the molten polymer exit. The die body includes a peripheral edge at a periphery of the molten polymer exit, which peripheral edge has a thickness less than or equal to about 0.005 inches. The apparatus further includes a molten polymer exit heated gaseous fluid supply adapted to provide heated gaseous fluid proximate the molten polymer exit so as to maintain the die temperature at the molten polymer exit as low as possible without affecting the processability/integrity of the product film.

    摘要: A breathable, substantially liquid impermeable laminate is provided that is permanently conformable to the contours of a wearer's body when used in a personal care absorbent article or a medical article. The laminate includes a breathable (preferably microporous) film and a fibrous nonwoven web. Both the film and the web are extendible in a cross direction to a width at least 25% greater than an original, unstretched width upon application of a stretching force. The web and the film, and the overall laminate, exhibit little or no retractive force once they have been stretched. A diaper or other garment can be constructed in undersized fashion using the laminate, permitting material savings. When the garment is worn, the laminate stretches only where needed to provide a substantially perfect fit on the wearer. The minimal retractive force avoids the skin marks, rashes, etc. that can result from elastic garments.
