ABSTRACT:
A packaging tray and, more particularly a high-strength, reinforced molded food packaging tray for use in packaging meats, fish, poultry and other comestibles which is adapted to be utilized in conjunction with a transparent overwrap film. The inventive packaging tray is provided with a novel peripheral lip structure which will aid in preventing the collapse or fracture of the tray sidewalls in view of pressures exerted by the overwrap film when applied to the tray in an automatic tray overwrap machine. In a particularly preferred embodiment of the invention, the packaging tray is provided with a novel tray bottom wall incorporating a reinforcing structure in the form of one or more strengthening ribs which are integrated in the bottom wall of the tray.
