Fast setting starch-based corrugating adhesive having partially hydrolized water soluble polyvinyl alcohol component

A dry blend composition that can be diluted with water to form a basic boric acid compound containing adhesive, which comprises a major proportion of a starch composition useful in corrugating adhesives, and an effective amount of a cold water soluble, partially hydrolyzed polyvinyl alcohol composition having a degree of hydrolysis of less than about 91%, that can increase the rate of formation of the green bond during corrugated board manufacture, wherein the concentration of the polyvinyl alcohol composition in the adhesive composition when diluted is about 0.25 to 1.25 parts of polyvinyl alcohol composition per each 100 parts of the adhesive composition.

A dry blend composition, that can be diluted with water to form an adhesive, which comprises a major proportion of a starch composition useful in corrugating adhesives, and an effective amount of a cold water soluble polyvinyl alcohol composition having a degree of hydrolysis of less than 91% which when fully diluted in a basic boric acid compound containing aqueous adhesive is present at a concentration of about 0.01 to about 1.5 parts of polyvinyl alcohol per each 100 parts of the adhesive composition, sufficient to increase the rate of green bond formation at temperatures below the temperature required to solubilize fully hydrolyzed polyvinyl alcohol in a corrugating adhesive.
