Nonwoven/film laminates
Abstract:
The invention relates to a method for producing nonwoven/film laminates for personal hygiene articles, from an initial film web consisting of a thermoplastic polymer and an initial nonwoven web. According to said method, the initial film web and the initial nonwoven web, whose melting point lies above the crystallite melting point of the polymer, are heated to a temperature that exceeds the crystallite melting point of the polymer and lies below the melting point of the initial nonwoven web. The laminate is then guided through a cooled nip and is cooled to a temperature that lies below the crystallite melting point of the initial film web. The invention also relates to laminates that can be produced by said method.
