Abstract: The packaging system comprises a reusable plate (1) with a base (10) and an edge (11), designed to receive a food portion, a disposable, heat-formed tray (2) receiving the plate (1) and a sealing film. The tray (2) conforms to the contour of the plate (1), with a flat base (20), a peripheral side (21) terminating at the top part with a flat edge (22) provided with a lug (23) for receiving the film (3). The point where the peripheral side (21) and the base (20) meet has two parallel indentations (26) for overlapping with two parallel guides (30), the base (20) being supported on a conveyor (31) in order to be conveyed between the different dispensing and sealing stations in a precise orientation.
