ABSTRACT:
Disclosed herein is a quilted film laminate wherein a film having a plurality of generally parallel slits is laminated to a substrate layer such as a fibrous nonwoven web. Due to processing conditions, once the slit film layer and substrate layer have been laminated to one another, the composite is allowed to retract thereby giving the composite a puckered or quilted appearance with an undulating surface. The undulating surface also causes the slits to form a plurality of openings which are generally perpendicular to the central plane of the film. In addition, due to the undulating nature of the surface of the film, the apertures so created reside in, above and below the central plane of the film layer. The composite so produced has a wide variety of uses not the least of which include a cover material or body side liner for personal care absorbent products. The process for producing the composite is also disclosed.
