Abstract

Wood fibers for medium density fiberboard (MDF) was used in the filler layer of the white duplex board for increasing thickness and bulk of the board. The MDF fibers and the old corrugated container (OCC) furnish were refined, and mixed together to form paperboard. At optimum mixing ratios and refining degrees, stiffness and tensile strength of the MDF fiber-containing board were higher than those of the board with 100% OCC. It was found that there was possibility to reduced basis weight of the filler layer down to 90% of the all OCC furnish by judicious selection of the mixing ratio and the refining method of the MDF fibers. Drainage rate increase and potential drying energy savings were additional benefits.
