An ovenable food tray for cooking foodstuffs, such as frozen foodstuffs, in an oven of either the microwave or conventional type. The tray is formed from a flat, unitary laminate blank by deforming the blank in any conventional male and female die apparatus under pressure and heat. The laminate includes a food contacting PET bi-axially oriented film coating adhered to a paperboard base stock by means of a crosslinkable adhesive. The use of such a coating and such an adhesive formulation permits use of the tray in oven temperatures to about 400 degrees F. without delamination of the coating from the paperboard or cracking of the coating.
