WATER VAPOR PERMEABLE CROSS-LAMINATED POLYMER FILM ASSEMBLY

Abstract:

A water vapor permeable polymer-based film assembly includes a first ply of a first water vapor permeable polymer having first polymer chains oriented in a first direction, a second ply of a second water vapor permeable polymer having second polymer chains oriented in a second direction that is transverse to the first direction, and an adhesive coupling the first ply of the first water vapor permeable polymer to the second ply of the second water vapor permeable polymer.
