Foil/Scrim/Kraft (FSK) facing papers are utilized as a vapor barrier wrap for ducts and pipes. Ahlstrom-Munksjö offers both bleached and natural options, available in machine-finished and machine-glazed surfaces.

Machine-glazed papers offer an ideal smooth surface for foil lamination. With basis weights as low as 11.5# and as high as 50#, we offer the widest breadth of papers in the industry.

Our papers incorporate treatments that minimize corrosion when in contact with metal surfaces like aluminum foil.
