Abstract
Laminated, paper cards are manufactured by adhering a first side of a calendared paper to a first side of a fiber board stock using a biodegradable adhesive to thereby create a sheet of material. A card construct is then formed by adhering a second side of the fiber board stock of a first sheet of material to a second side of the fiber board stock of a second sheet of material using a biodegradable adhesive. A second side of at least one of calendared papers of the card construct is then printed and the printed card construct is then subjected to a heat and pressure treatment in a hydraulic press. The treated, printed, card construct may then be die punched to provide one or more of the laminated, paper cards.
Claims19
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.
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 simultaneously applied heat and pressure treatment followed by a simultaneously applied cooling and pressure treatment;
- and
- punching from the treated, printed, card constructs one or more flat, laminated, paper cards.
