Title
(EN) PATTERN EMBOSSED MULTILAYER MICROPOROUS FILMS
(FR) FEUILLES MINCES MULTICOUCHES, MICROPOREUSES, GAUFREES SELON UN CERTAIN MOTIF
Abstract
(EN)
Pattern embossed low gauge films (10) are disclosed having multiple microporous film layers (12, 14) with distinct coloration, such as a dark colored layer (14) and a light colored layer (12), wherein the color of the underlying film causes a visible color contrast only at the embossed regions (16) and yet does not discolor the outermost layer. Also disclosed are film laminates and personal care articles incorporating such multilayer films.
(FR)
L'invention concerne des feuilles minces (10) de faible calibrage, gaufrées selon un certain motif et présentant plusieurs couches minces microporeuses (12, 14) de différente coloration, comme une couche de couleur foncée (14) et une couche de couleur claire (12), la couleur de la couche sous-jacente formant un contraste de couleur visible seulement au niveau des régions gaufrées (16), sans pour autant décolorer la couche située la plus à l'extérieur. L'invention concerne encore des stratifiés à base de telles nappes, de même que des articles d'hygiène personnelle comportant de telles nappes multicouches.
