Abstract
The invention is a paper/plastic laminate suitable for use in office, midrange and high-speed traditional laser and digital copiers and digital printers, and other like equipment using heat set fuser toner adhesion as the method for fusing/bonding an ink to a paper. The paper/plastic laminate comprises a paper web laminated to a plastic film using 100% solids adhesives. Employing 100% solids adhesive technology in the laminating process yields a more dimensionally stable paper/plastic laminate when the laminate is re-exposed to heat and the ability to make lighter paper/plastic laminates than otherwise possible using solvated or waterborne adhesives.
Claims19
A paper/plastic laminate comprising:
- a paper web having a top and bottom surface,
- a plastic film having a top surface and a bottom surface, the top surface of the plastic film being adhered by a 100 percent solids adhesive to the bottom surface of the paper web forming a paper/plastic laminate, the paper/plastic laminate being dimensionally stable, and
- wherein the paper web is treated to inhibit penetration of the 100 percent solids adhesive.
The method of making a dimensionally stable paper/plastic laminate comprising:
- selecting a paper web having a bottom surface,
- selecting a plastic film having a top surface,
- laminating the paper web bottom surface to the plastic film top surface using a 100 percent solids adhesive, the paper web, plastic film and 100 percent solids adhesive being selected such that the laminated combination is dimensionally stable, and
- wherein the paper web is treated to inhibit penetration of the 100 percent solids adhesive.
