摘要:
A method for manufacturing composite webs and composite webs made thereby in which the web includes a perforated thermoplastic film and one or more nonwoven webs. The method provides a perforated thermoplastic film, a creped nonwoven web, the webs are fed in a face to face relationship to be bonded. The perforated thermoplastic film and the creped nonwoven web are bonded in a face to face relationship at a plurality of points of contact such that the creped structure of the nonwoven web is maintained and the composite web has a nonwoven face and a film face. The composite webs are extensible at least in the direction of the creping.
