ABSTRACT:
A starch-based corrugating adhesive providing a controlled rate of viscosity increase and green bond formation comprising water, starch, caustic alkali, an active boron source, and polyvinyl alcohol having an intermediate degree of hydrolysis (about 92% to 98%), wherein the polyvinyl alcohol constituent imparts a definite increase in the rate of viscosity building of the adhesive, the rate of viscosity increase being controlled to provide an effective green bond and final adhesive bond on a corrugated board surface.
