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.
