Unbleached kraft Linerboard is a grade of paperboard used in the production of corrugated containers and boxes. The inner and outer facing (liner) is used in combination with the corrugating medium (the fluted inner sheet) to form the rigid structure of the combined board. Most unbleached kraft linerboard is made from the kraft process of softwood chips that have long fibers which make the strongest board. The standard kraft linerboard is 33#, 42#, or 69#.

This product is also used in making singleface, however it can be used for a variety of applications including lining rail cars, floor protection, pallet covers, and on construction sites.
