Abstract:
A refrigerated dough container (10) that has less than 5% non-paper material by weight such that the container qualifies as being a recyclable paper article. The container includes a paperboard body ply (12) and a liner ply (30) adhered to the inner surface of the body ply. The liner ply (30) consists of a paper layer (32) having an outer surface adhered to the inner surface of the container body, and at least one non-paper layer (36,38) imparting moisture/gas barrier and sealing characteristics to the liner. The total weight of the non-paper layer (s) does not exceed 5% of the combined body ply and liner ply weight. The non-paper layers can include a metallized film or thin foil as a barrier layer and a polyolefin or sealing varnish as a sealant layer. Alternatively, a single non-paper layer, namely a PVDC layer, can be extrusion-coated onto the paper layer.
