  • Impregnated corrugted sheets for packing boxes and method of manufacture
    Patent number: 4826714
    Abstract: The medium and liners of a water resistant containerboard are each essentially completely impregnated by a liquid water resistant agent which also uniformly coats the surfaces of the medium and liners with a layer sufficiently thick to cover the outer extremities of fibers protruding from such surfaces.The coating and impregnation is accomplished by feeding a flat untreated corrugated containerboard in the direction of its open flutes and in a continuous movement into and out of a hot melt bath of the water resistant agent at a controlled speed sufficient to force the liquid agent through the flutes of the containerboard, so as to assure exposure of all surface portions of the board to the hot melt for the same amount of time at the same temperature conditions.
