  • High performance bulk box with repulpable water vapor barrier
    Patent number: 6722560
    Abstract: A bulk box of corrugated cardboard has a readily repulpable water vapor barrier material incorporated in the outer liner, increasing the resistance of the box to penetration by moisture in humid conditions, and especially reducing hysteresis effects in conditions of cyclic humidity. The box has increased strength and bulge resistance, and achieves performance equally as good as or better than a conventional box without the water vapor barrier, while at the same time enabling less pulp fiber to be used in the construction of the box.
    Type: Grant
