Abstract
A laminated paperboard package is produced by initially printing graphics by high speed printing on a sheet of clay-coated publication paper. The printed paper is then continuously bonded to a surface of cellulosic base layer, to provide a laminated product. The cellulosic base layer consists of at least one base ply of unbleached fibers and at least one ply of bleached or dyed fibers. Alternatively, instead of a ply of bleached or dyed fibers, a second layer of paper may be laminated to the base ply. The laminated product is then die cut to the desired shape, folded and glued into the configuration of a box or container. The substrate may be either coated, or a ply is provided, to prevent moisture or oil from the contained product from seeping through the base layer to the printed paper.

A carton comprising a laminated composite sheet folded and glued in the configuration of a box, said sheet comprising:
- a fiberboard base layer, said base layer comprised of at least one base ply of unbleached cellulosic fibers selected from the group consisting of unbleached virgin kraft pulp and recycled pulp, said base ply having an inner surface and an outer surface;
- at least one inner ply of cellulosic fibers on the inner surface of said base layer selected from the group consisting of dyed virgin pulp, dyed recycled pulp, bleached virgin pulp and bleached recycled pulp;
- an outer layer with printed graphics thereon;
- and
- a separate layer of adhesive disposed between said base layer and said outer layer serving to bond the outer layer to the base layer, the outer layer being bonded continuously to the outer surface of said base layer.
A carton comprising a laminated composite sheet folded and glued in a configuration of a box, said sheet comprising:
