Patent ID: 8083883

Claim:
A method for making a laminated, paper card, comprising: adhering a first, flat side of a calendared paper to a first, flat side of a cellulose fiber board stock using a biodegradable adhesive to create a first, flat sheet of material; adhering a first, flat side of a calendared paper to a first, flat side of a cellulose fiber board stock using a biodegradable adhesive to create a second, flat sheet of material; adhering a second, flat side of the cellulose fiber board stock of the first, flat sheet of material to a second, flat side of the cellulose fiber board stock of the second, flat sheet of material using a biodegradable adhesive to create a flat, card construct; providing a print to a second, flat side of at least one of the calendared papers of the flat card construct; subjecting the printed card construct to a heat and pressure treatment in a hydraulic press; and punching from the treated, printed, card constructs one or more flat, laminated, paper cards; wherein the heat and pressure treatment comprises subjecting the printed card construct to a temperature between approximately 230 degrees F. and approximately 240 degrees F. at a pressure of approximately 150 psi and then subjecting the printed card construct to a temperature between approximately 60 degrees F. and approximately 70 degrees F. at a pressure of approximately 300 psi.
