Abstract: Molded pulp plate having continuous unseamed liner of polypropylene film bonded to its interior surfaces by pigmented polyamide ink, or a pigmented resin emulsion, which serves as adhesive and also provides all or part of a decorative design visible through the transparent film. Underside of polypropylene film may have further decorative printing of conventional ink, the adhesive being printed or coated thereover. Method includes clamping a sheet of polypropylene film, having the dried resin adhesive on its underside surface, against the smooth rim of the plate; heating the plate and film to a temperature which is above the softening point temperature of the resin constituent of the pigmented coating but below the softening point temperature of polypropylene; and drawing a vacuum through the bottom of the plate to press the film against the interior surfaces of the plate.

Abstract: MOLDED PULP PLATE HAVING CONTINUOUS AND UNSEAMED LINER OF POLYPROPYLENE FILM BONDE%D TO ITS INTERIOR SURFACES BY POLYETHYLENE. UNDERSIDE OF POLYPROPYLENE FILM MAY BE PRINTED WITH DECORATIVE DESIGN. METHOD INCLUDES CLAMPING A SHEET OF POLYPROPYLENE FILM, HAVING POLYETHYLENE COATING ON ITS UNDERSIDE SURFACE, AGAINST THE MOUTH RIM OF THE PLATE; HEATING THE PLATE AND FILM TO A TEMPERATURE WHICH IS ABOVE THE SOFTENING POINT TEMPERATURE OF THE POLYETHYLENE MATERIAL BUT BELOW THE SOFTENING POINT TEMPERATURE OF POLYPROPYLENE; AND DRAWING A VACUUM THROUGH THE BOTTOM OF THE PLATE TO PRESS THE FILM AGAINST THE INTERIOR OF THE PLATE.
