ABSTRACT:
A method for adhesively bonding opposed paperboard surfaces to each other to form a strengthened bond in a paperboard product and paperboard products formed thereof, comprising the steps of (A) applying a green-strength adhesive to at least a portion of the first paperboard surface; (B) applying a styrene-butadiene latex adhesive or a modified styrene-butadiene latex adhesive as a strengthening adhesive to at least a portion of either the first or the second paperboard surface such that the green-strength adhesive is substantially offset from the strengthening adhesive when the first and second paperboard surfaces are positioned in an opposed relationship; (C) orienting the first and second paperboard surfaces such that they are opposed to each other; and (D) contacting the first and second surfaces together to form the strengthened bond. In addition, there is provided a method for adhesively bonding opposed paperboard surfaces to form a strengthened bond in a paperboard product, and paperboard products formed thereof, by applying a strengthening adhesive consisting essentially of a styrene-butadiene latex adhesive or a modified styrene-butadiene latex adhesive to at least a portion of the first paperboard surface and contacting together the paperboard surfaces to form the strengthened bond.
