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.
