A repulpable and recyclable case ready food tray is disclosed for carrying various food items, such as meat, poultry and produce that is typically used for retail display. The food tray is formed from paperboard made from natural wood fiber that is coated to provide a waterproof food cavity for preventing leakage of liquid from the food item and a moisture proof exterior support surface which allows excess liquid to be released from the food tray during the manufacturing process while providing a moisture proof surface to prevent wicking of liquid into the food tray if the tray is placed on a wet surface.
