Estimating the term…
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.
A substantially liquid-impermeable laminate that is conformable to contours of a wearer's body, the laminate comprising:
A breathable, substantially liquid-impermeable laminate that is extendible in a cross direction to a stretched width at least 25% greater than an original, unstretched width upon application of a stretching force, and retractable by zero to not more than 30% of a difference between the stretched width and the original width upon relaxation of the stretching force after 60 seconds, the laminate comprising:
A breathable, substantially liquid impermeable laminate having a WVTR of at least 300 grams/m2—24 hours, comprising:
