Abstract: A process for continuously coating two sides of a heat fusible foam sheet with a resinous polymeric material, having the steps of: (1) melting the resinous polymeric material; (2) extruding the resinous polymeric material through a flat film die; (3) continuously passing the heat fusible foam sheet past the flat film die; (4) contacting the heat fusible foam sheet and the resinous polymeric material; (5) compressing the contacted heat fusible foam sheet and resinous polymeric material; (6) limiting the amount of reverse wrap of the heat fusible foam sheet and; (7) controlling the linear tension on the heat fusible foam sheet.

Abstract: Disclosed is a foamed-plastic hot food container including a tray and a cover hinged to the tray. Both the tray and cover include a generally V-shaped divider and support member which divides both the tray and cover into cavity sections and which, when the cover is fitted over the tray, abut each other to impart structural rigidity to the container. The tray also includes cover-receiving means which keeps dirt out of the container and heat in the container.
