Beschreibung
Zusammenfassung:	There is disclosed a nonwoven web/film laminate for use as a fabric in personal care products. The laminate is formed of at least two layers in an SF formation. The spunbond (S) layer of the laminate is formed of preferably metallocene catalyzed polypropylene. The film (F) layer is formed of a polyolefin which may be metallocene-catalyzed. La présente invention concerne un laminé bande/film non tissé destiné à un tissu pour produits d'hygiène personnelle. Ce laminé est constitué par au moins deux couches en formation SF. La couche liée par filage (S) du laminé est formée préférence par un polypropylène catalysé par métallocène. La couche film (F) est constituée par une polyoélfine éventuellement catalysée par métallocène.
