Document Type and Number:
Japanese Patent JP2006509660
Kind Code:
A
Abstract:
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.
