Abstract
This application describes a method of preparing starch-based corrugating adhesives which involves treating the wash water in flexographic printing processes to remove ammonium ions and subsequently reusing the water in preparing the adhesives. The preferred process includes the steps of separating the ink solids from the wash water, recovering a liquor, and removing ammonium ions from the liquor to condition the liquor for subsequent use in preparing corrugating adhesives.
