An all natural, starch-based, alkaline corrugating adhesive free of formaldehyde and other crosslinking and water resistance additives and having good water resistant properties comprising an aqueous dispersion of a gelatinized carrier starch and a raw ungelatinized starch wherein the carrier starch has a total amylose content of greater than 60% by weight and the gelatinized starch amylose content is at least about 15% by weight of the total starch content in the adhesive.

All natural, starch-based, water resistant corrugating adhesive

This invention provides a starch derived from a single plant source, comprising less than 10%, optionally less than 5%, amylopectin. The starch additionally comprises at least 75% amylose, optionally at least 85% amylose, measured by butanol fractionation/exclusion chromatography measurement. In another aspect of this invention, the starch is extracted in substantially pure form from a starch bearing plant having a recessive amylose extender genotype that is associated with amylose extender modifying genes. The starch bearing plant from which the starch is extracted is preferably a maize plant.
