    摘要: The present invention provides a water-resistant corrugated fiberboard sheet having a high water resistance and capable of being recycled after the use. The recyclable, water-resistant corrugated fiberboard sheet of the present invention comprises a water-resistant linerboard adhered to both surfaces of a corrugated, water-resistant core sheet. The water repellency (JIS P8137) of at least one of both surfaces of the corrugated, water-resistant core sheet and the core sheet-side surface of the water-resistant linerboard in the recyclable water-resistant corrugated fiberboard sheet is at least R 6 and that the Cobb water-absorption (JIS P8140; contact time: 30 minutes) of the surface of the corrugated fiberboard sheet is not higher than 30 g/m2.

    摘要: Corrugating adhesives of the carrier, no-carrier and carrier-no-carrier type having excellent dry pin adhesion, green strength and improved water resistance are prepared with solubilized plant fiber as a complete or partial substitute for starch. The adhesive composition contains polyvinyl alcohol, solubilized fiber and, optionally, from about 0.1% to about 99% added starch by weight based on total solubilized fiber and added starch. When the adhesive is the carrier type or the carrier-no-carrier type, the fiber can be solubilized in situ during the process of preparing the carrier phase.

    摘要: A high speed corrugating adhesive having a carrier phase comprised of starch, modified starch or dextrin and polyvinyl alcohol in an aqueous emulsion wherein a cold water soluble, partially hydrolyzed, polyvinyl alcohol is used as a starting material. The polyvinyl alcohol is further hydrolyzed in situ to a degree of hydrolysis of more than about 95% by heating it in the presence of water, caustic, and starch, modified starch or dextrin. The carrier phase is admixed with a boron containing compound and a suspension of water and starch to prepare the corrugating adhesive for use in a corrugating machine.
