Abstract: A dry blend pre-mixture composition for use in making corrugating adhesives is comprised of starch and from about 5% to about 20% of ground plant germ. The starch and germ can be derived from various plant sources and in a preferred embodiment the starch is corn starch and the germ is ground corn germ, also known as spent flake. The corrugating adhesives can be prepared by using the pre-mixture as a replacement for starch in a process for making a carrier, no-carrier or carrier-no-carrier adhesive.

Abstract: An instant corrugating adhesive composition comprising a dry blend of starch and a dried pre-solubilized cellulosic extract. The composition can easily be rehydrated with water to make a corrugating adhesive. The corrugating adhesive is formulated without boron compounds and with minimal or no addition of alkali. The dried pre-solubilized cellulosic extract, which includes hemicellulose as a major component, functions as the carrier portion of the corrugating adhesive. No initial cooking step is required to make the carrier and rehydration can be conducted at ambient temperatures.
