Abstract: The invention relates to a method for manufacturing a board tray (7), to a tray blank feasible for the method, and to a tray obtained by the method. The method comprises moulding a blank of plastic-coated board into the tray (7) comprising a bottom (3), side walls (4), as well as a rim flange (5), the blank being compressed in a direction transverse to the tray's side walls and rim flange. According to the invention, the blank is made thinner on its side opposite to the plastic coating such that, during the moulding process, the plastic coating double-folds at the compressed parts and stabilizes compressions (8) by becoming sealed to itself. Making the blank thinner is most conveniently effected by carving the board layer with a laser beam for having the fiber material predominantly or completely removed from where the cuts are located. As a result of the moulding process, the tray's rim flange (5) develops a smooth plastic surface which enables closing the tray hermetically with a heat-sealed cover.

Abstract: The invention relates to a ready-made food package, to a method for manufacturing it and to the use of polymer-coated board in the ready-made food package. The package is manufactured by placing the food (16) in a raw state in the tray (2) where the food is baked, and by closing the tray with a lid (4) after baking. In accordance with the invention, the lid (4) is formed from a blank cut from polymer-coated board, the blank being placed over the mouth of the tray (2), and then the edges (9) of the blank are bent under the rim flange (6) of the tray and heat-sealed to the lower surface (11) of the rim flange by means of the polymer coating (14) of the board. The lid can be additionally heat-sealed to the upper surface (10) of the rim flange, so that two sealing lines (15) will be formed inside each other in the package. Accordingly, the tray (2) can be formed of polymer-coated board or optionally of polymer or aluminium alone.
