Freight floor, freight container, use of a multilayer panel to produce a freight floor, and method for producing a freight floor

A freight floor comprising:

• first and second core layers of fibre-reinforced plastic,
• a foam layer arranged between the first core layer and the second core layer, the foam layer including foam and a plurality of cavities in the foam layer,
• a seating layer of a metal alloy, wherein one of the core layers and the seating layer are connected together by material fit and/or by form fit,
• wherein the foam layer comprises foam and a supporting structure made of synthetic resin, the supporting structure being formed in the cavities of the foam layer and extending vertically to the freight floor and firmly joining the first and second core layers, the synthetic resin of the supporting structure joining the first core layer and the second core layer by material fit, wherein the foam has a low density and is at least partially saturated with the synthetic resin to reinforce the freight floor.
