Nonwoven laminate products having improved wet peel strength after aging
and ethylene oxide sterilization, and improved drape and softness, which
are suitable for medical, surgical and hygienic applications, are
produced by laminating one or more nonwoven substrates on one or both
sides of a cast film. The cast film is produced using conventional
extrusion processes, such as co-extrusion. Multiple extruders are used to
process and melt different polymers and then specially designed selector
plugs and feed-blocks are used to combine the different polymers into
different layers to form a multiple layer structure such as A-B, A-B-A,
A-B-C, A-B-B-A, etc.
