ABSTRACT:
A paper food container is disclosed having a bottom flange and formed form a paper board blank. The blank has a predetermined thickness and is cut into a predetermined pattern. Since the container will accommodate food products, the paper board is made of pure fiber and additives meeting FDA regulations. The blank is coated with polyethylene and laminated to an adequate thickness. The paper board is further embossed with folding lines so that the paper board can be folded about the folding lines and heat-sealed to form a bowl-like paper food container having a bottom formed with a flange which reinforces the paper food container and permits a user to securely hold the paper food container without being burned by the heat of the hot food contained in the paper food container.
