Abstract
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.
