Abstract
A novel carrier composition for corrugating adhesives contains 1 part amylaceous material, about 3 to 5 parts water, and about 0.5 to 4 parts urea. The carrier is self-gelling at room temperature, and lowers the gel temperature of the adhesive paste to within the optimal range for use in making corrugated paperboard. The carrier is especially well-suited for use in acidic adhesive systems since its effect on the gelatinization temperature of the raw starch component is independent of pH.
