Method for producing autoclaved foodstuffs in a container made of a sheet-like composite with a colored cross-linked outer polymer layer obtainable by gravure printing

摘要

The invention relates to a method for producing a closed, food - filled container (3) that closes an interior space (1) from an environment (2) from at least one sheet - like composite (7) that has at least one edge (4), comprising the steps: f) providing the sheet-like composite (7), comprising a1. at least one outer cross-linked plastic color layer (9) containing a colorant (20), wherein the plastic color layer (9) contains a polyaddition product; a2. a carrier layer (6); and a3. a thermoplastic layer (16); g) shaping the sheet-like composite (7) to obtain an open container (14), the plastic color layer (9) facing the surroundings (2) and the plastic layer (16) facing the interior (1); h) filling the open container (14) with a food; i) closing the open container (14) while maintaining the closed, filled container (3); Preserving the food in the closed, filled container (3) in a pressure chamber under a chamber pressure of more than 1 bar at a temperature in a range of more than 100 to 140 ° C in the presence of water vapor.
