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.

Abstract: The invention relates to a heat-sealing method, in which a polymer material (1) forming the seal is melted or softened with an air flow (4) blown to the sealing point (11). In accordance with the invention, water (7, 9) is added to the air flow in order to increase the moisture content of the hot sealing air. The air is heated by resistance heating or flame heating and the water can be introduced in the hot air flow in the form of water, which subsequently evaporates, or in the form of water vapour. The method is suitable i.a. for producing packaging containers by sealing polymer­coated paper or board.

Abstract: The invention relates to a method for sealing a fiber-based material (1, 4) to a counter-surface to be bonded to it by melting polymer present at the sealing point. In accordance with the invention, the sealing is performed by directing a laser beam (8) through the fiber layer (4) of the material to a radiation-absorbing pigment disposed in the sealing area (9), with the absorption heat melting the polymer (5) and generating the sealing. The method allows sealing of plastic-coated paper or board to itself, to another plastic counter-surface or also to paper or board without any plastic coating. It is also possible to seal uncoated paper or board to paper or board containing plastic, such as plastic-coated paper or board, or to a plastic film. The absorptive pigment, e.g. carbon black, may be admixed in the plastic coating of the board or paper or the plastic film formed on the counter-surface, or the pigment may be located on the surface of the material to be sealed or its fiber layer, or on the counter-surface to which the material is sealed, e.g. as a component of printing ink applied to the counter-surface.
