Title (EN) LATENT ELASTIC OLEFIN FILM LAMINATES AND METHODS OF MAKING ABSORBENT ARTICLES INCORPORATING THE SAME
(FR) STRATIFIÉS DE FILM OLÉFINIQUE À ÉLASTICITÉ LATENTE ET PROCÉDÉS DE FABRICATION D'ARTICLES ABSORBANTS LES INCORPORANT
Abstract:
(EN) A latent elastic film laminate is provided including a film predominantly comprising olefin elastomers. The film is stretched and maintained in a stretched state in order to impart the desired level of latent elasticity such that the conditioned film laminate will shrink upon activation, such as by heating. The latent elastic film laminate can be advantageously used in the manufacture of various elasticated articles, including absorbent personal care articles, by activating the latent elasticity after attachment to the article and thereby shirring and elasticizing components to which the film laminate is attached.
(FR) L'invention concerne un stratifié de film à élasticité latente comportant un film comprenant principalement des élastomères oléfiniques. Le film est étiré et maintenu dans un état étiré afin de conférer le niveau souhaité d'élasticité latente de sorte que le stratifié de film conditionné se rétracte lors d'une activation, telle que par chauffe. Le stratifié de film à élasticité latente peut avantageusement intervenir dans la fabrication de divers articles auxquels sont conférées des propriétés élastiques, comprenant des articles absorbants de soins personnels, par activation de l'élasticité latente après fixation à l'article et procurant ainsi un fronçage et une élasticité à des composants auxquels le stratifié de film est fixé.
