Title (EN) FILM, LAMINATED SHEET AND METHODS OF MAKING SAME
(FR) FILM, FEUILLE STRATIFIEE ET PROCEDES DE FABRICATION CORRESPONDANTS
Abstract:
(EN) A method of making a microporous laminate sheet having a first film layer and a second layer. The first film layer includes a pore initiator and is bonded to the second layer in order to form a laminate sheet. The laminate sheet is then stretched using at least one CD intermeshing stretcher (28) and at least one MDO stretching unit (29). Methods of making a microporous film laminate are also provided, along with an apparatus for stretching a film or laminate.
(FR) L'invention concerne un procédé de fabrication d'une feuille stratifiée microporeuse constituée d'une première et d'une seconde couches de film. La première couche de film comprend un agent initiateur de pores et elle est lié à la seconde couche de façon à former une feuille stratifiée. La feuille stratifiée est ensuite étirée au moyen d'au moins une unité de rouleaux à nervures engrenantes (28) étirant dans la direction transversale et d'au moins une unité de rouleaux (29) étirant dans le sens de la machine. L'invention concerne aussi des procédés de fabrication de stratifié de film microporeux, ainsi qu'un appareil d'étirement d'un film ou d'un stratifié.
