Abstract
A corrugating adhesive that improves the bonding of coated papers, including latex coated medium and linerboards. The corrugating adhesive may comprise a hydrocolloid portion of the adhesive that improves tack and bonding and buffers and absorbs caustic in the adhesive allowing higher caustic in the adhesive formula without premature gelling of the secondary starch portion. Also, methods for making waterproof or water resistant corrugated board from corrugated media and paper liner.
