The invention concerns a deep-drawn paper tray (4), particularly a shallow tray made of paperboard or cardboard, a method and an apparatus for manufacturing such a tray by deep-drawing techniques, and a closed product package comprising the tray of the invention, particularly a heat-sealed gas- and liquid-tight food package. The tray comprises a bottom (4a) and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps (4b, 4c, 4d) dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange (4d), which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus according to the invention may comprise upper and lower moulding tools (10, 11) with concentric movable frames (10b, 10c, 10d) for forming the tray bottom and side wall steps to paper blanks, and moulding tools (10) may be mounted onto a rotating turret (9) carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.
