Abstract

A laminate having improved extensibility is made of an elastic sheet layer prestretched and bonded to at least one extensible layer. In a first embodiment, the elastic layer is bonded in selected locations to an extensible layer and then heated. The latent extensibility of the prestretched elastic layer and the extensibility of the extensible layer produce desired extensibility useful as waistbands, side panels and side tabs in diapers and training pants. Diapers and training pants made with such a material can fit a larger number of body sizes because of the improved extensibility. In a second embodiment the film is prestretched in the cross direction and the machine direction, then laminated to an extensible layer, resulting in two-way extensibility. The elastic layer can be apertured. Aperturing produces a laminate that is breathable, while maintaining improved extensibility.
