A molded tray for the packaging of a product such as poultry in conjunction with an overwrap film applied while the tray is transported through a packaging machine having a pair of conveyor belts with opposed vertical belt surfaces between which the tray is gripped and travels during packaging, comprising: (a) a substantially flat bottom wall for supporting the product being packaged; (b) upwardly and outwardly inclined side walls having and extending from upper ends to the bottom wall and joined by a smooth transitional inner surface to said bottom wall along an inner boundary and forming the sides and ends of said tray, said side walls each having an outer peripheral substantially vertical planar gripping surface to enable said tray to be engaged by the vertical surfaces pressing inwardly against said planar gripping surfaces on the sides of the tray in a manner wherein said tray tends not to slip relative to the conveyor belts while being transported thereby; and (c) a reinforcing rib portion at the inner boundary of said side and bottom walls formed to rigidify and strengthen said tray to prevent breakage thereof during gripping and transport by said belts and to permit the outer surface of said walls to be formed with planar surfaces for flat sealing of the film, said rib portion forming said smooth transitional inner surface.
