A package including a tray () provided with a base (), a plurality of sidewalls () extending upwardly and slightly outwardly from said base (), a primary flange () integrally joined to the upper edges of the sidewalls () and extending outwardly all around the upper periphery of the sidewalls (), a rim (), i.e., a downward flap extending downwardly and tapering slightly outwardly from the outer periphery of the primary flange (), and a secondary flange (), i.e., an overhanging portion extending outwardly from the lower edge of the rim (), said tray being characterized in that a plurality of strengthening ribs () extend substantially vertically along the rim () and outwardly with respect to the tray body. The trays () according to the present invention have an improved rigidity and improved resistance to deformation and bending, improvements that have been achieved without increasing the amount of plastic material used for the manufacture of the tray () but relying only on a specific geometry thereof.
