Laminated package and method of producing the same
View Patent ↗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 applied to a surface of cellulosic substrate and bonded to the substrate, preferably through use of starch as an adhesive, to provide a laminated product. The laminated product is then die cut to the desired shape, folded and glued into the configuration of a box or container. A layer of water absorbent, cellulosic fiber material can be bonded to the inner surface of the substrate to prevent moisture from the contained product from seeping outwardly through the substrate to the printed paper.
1. A laminated beverage carrier for beverage containers comprising a laminated composite sheet folded and secured in the configuration of a box, said sheet comprising a non-corrugated base layer of unbleached cellulosic fibers and having an inner surface and an outer surface, an outer layer of separately formed non-corrugated paper having an inner surface and an outer surface, printed graphics disposed on the outer surface of the outer layer, and adhesive disposed between the inner surface of the outer layer and the outer surface of the base layer and serving to bond the outer layer to said base layer, the inner surface of said outer layer being bonded continuously to the outer surface of said base layer.
2. The laminated beverage carrier for beverage containers of claim 1 wherein said cellulosic fibers are selected from the group consisting of unbleached virgin kraft pulp and recycled pulp.
3. The laminated beverage carrier for beverage containers of claim 1 further comprising a layer of water absorbent material disposed on the inner surface of said base layer.
4. The laminated beverage carrier for beverage containers of claim 3 further comprising a film of water resistant adhesive bonding said absorbent material to said base layer.
