METHOD FOR THE PRODUCTION OF AUTOCLAVED FOOD IN A RECEPTACLE FORMED FROM A LAMINATE COMPRISING A COLORED CROSS-LINKED OUTER POLYMER LAYER OBTAINED IN A GRAVURE PRINTING PROCESS

摘要

The invention relates to a method for producing a closed receptacle (3) that seals an interior (1) from surroundings (2), is filled with food, and is made from at least one laminate (7) comprising at least one edge (4). Said method includes the following steps: f) providing the laminate (7) that includes: a1. at least one outer cross-linked colored plastic layer (9) containing a dye (20) and a polyaddition product; a2. a support layer (6); and a3. a thermoplastic material layer (16); g) forming the laminate (7) so as to obtain an open receptacle (14) in which the colored plastic layer faces the surroundings (2) and the plastic layer (16) faces the interior (1); h) filling the open receptacle (14) with food; i) closing the open receptacle (14) so as to obtain the closed, filled receptacle (3); preserving the food in the closed, filled receptacle (3) in a pressure chamber at a chamber pressure exceeding 1 bar and at a temperature ranging from more than 100 to 140°C in the presence of steam.
