    Abstract: The invention relates to a disposable container of fibrous board comprising a bottom (3) and an upward mantle (2) heat-sealed thereto. The material for both the bottom and the mantle is a polymer coated fibrous board, in which the coating covers at least the inner surfaces of the container. According to the invention the material comprises a fibrous board base (8) such as paperboard or cardboard, an extruded inner coating layer (9) of a blend of polyethylene (PE) and polypropylene (PP), and an extruded outer coating layer (10) of polypropylene-olefin copolymer (PP-c). The inner coating layer (9) secures adhesion with the board base (8) and the outer coating layer (10) is for liquid-proof heat-sealing between the bottom (3) and the mantle (2) of the container. The container is in particular a microwave ovenable cup or food tray.
