摘要： Foldable boxboard made by dry-laying cellulosic fibers and 1-10% starch. The boxboard has a weight of at least 210 g.s.m., a stiffness in the machine direction of at least 5.8 Kenley units, and a ratio of stiffness in the machine direction and in the cross-machine direction of substantially 1:1.

摘要： A process for making a multi-ply consolidated dry-formed fibrous web having at least three plies, the outer plies are impregnated with a stiffening agent (e.g. starch) and the intermediate plies are impregnated with a sizing agent (e.g. wax/rosin size) to render them impervious to the stiffening agent. After the web has been consolidated by hot moist pressing, its outer surfaces may be further sized and hot moulded.
