Also referred to as XKL papers, extensible kraft papers provide maximum strength and stretch properties for the most demanding converting applications. Used in a variety of markets and applications, Ahlstrom-Munksjö’s XKL paper is a strong, lightweight sheet capable of withstanding great impact without bursting or puncturing.

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 coming in contact with metal surfaces like aluminum foil.
