A process is described for manufacturing a paperboard from a high consistency slurry containing high levels of crosslinked cellulosic fibers by dispersing the fibers in a screen with a rotor in the screen and then passing the fibers through the screen basket with a hole diameter of at least 2 mm and forming the cellulosic fibers on a foraminous support. Another slurry of regular cellulosic fibers is deposited on at least one side of the first slurry during the formation process. The formed web is dewatered and dried.
