Method of manufacturing corrugated paperboard product using a foamed adhesive

A vinyl acetate ethylene copolymer adhesive obtains the production of a corrugated paperboard product at ambient temperatures without the need for the heat inputs heretofore required. The adhesive is foamed to expand it so that less adhesive material is required to a given quantity of product.
