Title
(EN) HEAT SHRINKABLE ELASTOMERIC LAMINATE MATERIAL
(FR) MATIERE STRATIFIEE ELASTOMERE THERMORETRACTABLE
Abstract
(EN)
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.

Un stratifié présentant une extensibilité améliorée est fabriqué à partir d'une couche élastique préétirée et liée à au moins une couche extensible. Dans un premier mode de réalisation, la couche élastique est liée en des régions prédéterminées à une couche extensible, puis est chauffée. L'extensibilité latente de la couche élastique préétirée et l'extensibilité de la couche extensible engendrent l'extensibilité désirée, qui peut être utilisée pour les ceintures montées, les panneaux et pattes latéraux des couches et des culottes de propreté. Les couches et culottes de propreté fabriquées avec une telle matière peuvent s'adapter à un grand nombre de tailles, grâce à l'extensibilité améliorée. Dans un second mode de réalisation, le film est préétiré dans la direction perpendiculaire et dans la direction de production, puis est stratifié avec une couche extensible, ce qui résulte en une extensibilité bidirectionnelle. La couche élastique peut présenter des ouvertures, ce qui rend le stratifié respirant, tout en lui conservant une extensibilité améliorée.
