Flange system has barrier layer sandwiched between polymeric layers acting as a inhibit

摘要

The system (82) comprises a closed wall (84) having internal surface defining internal aperture (85), external surface defining first and second ends, and first and second polymeric (94,96) and barrier (88) layers which surrounding the aperture. The distance between the ends is less than the minimal width of the flange system. An independent claim is also included for process of manufacturing the flange.
