"DRY COMPOSITION, WHICH CAN BE HYDRATED WITH WATER TO PRODUCE A CORRUGANT ADHESIVE, CORRUGANT ADHESIVE COMPOSITION, COMPOSITION AND PROCESS TO PRODUCE A CORRUGANT ADHESIVE, PROCESS TO HYDRATE A COMPOSITION AND TO PRODUCE CORRUGATED CARDBOARD AND CORRUGATED CARDBOARD. An instant corrugating adhesive composition comprising a dry mixture of starch and a dry pre-solubilized cellulosic extract. The composition can be easily rehydrated with water to produce a corrugating adhesive. The corrugating adhesive is formulated without boron compounds and with minimal addition or without addition of alkali. The dry pre-solubilized cellulosic extract, which includes hemicellulose as the main component, functions as the vehicle portion of the corrugating adhesive. No initial cooking stage is required to produce the vehicle and rehydration can be conducted at room temperatures.
