ABSTRACT:
The subject matter of the invention is a bottom panel for ventilated containers. The bottom panel is provided with an upper surface plate layer (1) and a lower surface plate layer (2), both layers being held in position by means of a spacer layer (3) of rigid foam. The upper surface plate layer (1) is an extruded profile consisting of a flat plate (4) and rib profiles (5), whereby the rib profiles (5) have a cross section of closed hollow profiles. The closed hollow profiles can be used as ventilation channels (7), which are linked to the grooves (6) between the rib profiles (5) by means to openings (8).
