Abstract
A biaxially extendible, breathable laminate having liquid barrier properties and low retractive force. The laminate includes a nonwoven web neck-stretched in a first direction to impart extendibility of the web in a second direction mutually perpendicular with the first direction, and a film that is extendible in the second direction. The film can be a breathable, microporous film, and can either be an inelastic film stretched to form rugosities in the second direction, or can be made of an extendible polymer that is extendible in the second direction. Using an appropriate elastomeric lamination and/or creping adhesive, the laminate is creped to produce extendibility in the first direction with some retractive force. The biaxial extendible laminate is particularly useful as an outer cover for diapers and other personal care products.
