Abstract: Un método de fabricación de una bandeja de cartón (4) por embutición profunda, comprendiendo el método las etapas de colocar una pieza en bruto de cartulina o cartón (1) con un peso de 120 a 500 g/m2 entre unas herramientas de moldeo superior e inferior (2, 3; 10, 11; 12, 13), y mover las herramientas de moldeo la una en relación con la otra para formar un fondo de bandeja (4a) y expandir hacia arriba unas paredes laterales que rodean el fondo, en donde mediante la mediante la multiplicación del escalón de pared lateral que se forma en una sola o una pluralidad de etapas de trabajo, las paredes laterales de la bandeja se moldean para tener un perfil concéntricamente escalonado (4b, 4c, 4d) alrededor del fondo de bandeja, caracterizado por que cada uno de los escalones de pared lateral (4b , 4c, 4d) está dimensionado para tener una altura de 6 mm como máximo con el fin de obtener unas paredes laterales sin arrugas para la bandeja (4).

Abstract: The invention concerns a method of manufacturing paper or board, the paper or board obtained by the method, and a method of producing a tray from the board. In a fibrous stock for papermaking is incorporated an amount of polymer coated fibrous particles, which even have a foaming agent such as moisture contained therein. A web is formed from the fibrous stock on a forming fabric of a paper or board machine, followed by pressing and drying to a finished paper or board. As the paper or board is sufficiently heated the foaming agent within the particles evaporates, causing expansion and foaming of the polymer coating, which adds to malleability of the board as it is moulded into a shaped article such as a board tray. The invention even covers production of doubly coated fibrous particles for use in said methods, the inner coating layer being of a foamable polymer with a higher melt flow rate and the outer coating layer being of a non-foaming polymer of a lower melt flow rate.

Abstract: 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.
