Abstract (en)

A paperboard is made by a process using a high consistency pulp slurry containing high levels of crosslinked cellulosic fibers, 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 and the resulting web is dewatered and dried.
