A container having walls made of a paper/plastic laminate having a cardboard core sandwiched between inner and outer face liners, wherein at least one of the face liners is comprised of a face liner laminate. The face liner laminate is composed of an exterior ply of oriented synthetic plastic film whose opposing surfaces are rendered wettable by corona-discharge treatment, and a base paper ply is cold-laminated to the film ply and adhered to the core of the board. The cardboard core may be a fluted medium of corrugated paper board, or it may be a planar stiff paper core. The invention is also directed to a structural member for use in making inexpensive furniture comprising a supporting member and a cardboard core laminated to a face liner laminate. The film ply of the laminate enhances the strength of the container or structural member and imparts water resistance thereto. Because the exposed surface of the film ply is printable, it may have decorative graphics or other printed matter applied thereto.

[ What is claimed is:] [1.] A container having walls made of a paper/plastic laminate comprising:a first paper layer having first and second surfaces;an outer face liner comprising a plastic film having first and second surfaces, wherein the first surface of the plastic film is corona-discharge treated to render it wettable and receptive to adhesives, and the corona-discharge treated first surface of the plastic film is laminated to the first surface of the paper layer with a first water-based adhesive;a cardboard layer comprising at least one paper sheet, with the layer having first and second surfaces; andan adhesive on the second surface of the paper layer for joining the second surface of the paper layer to the second surface of the cardboard layer to form a laminate which imparts enhanced strength and water-resistance to the container walls.
