to achieve the desired interior pan finish without substantially changing the overall pan shape or thickness any suitable temperature resistant plastic film can be used for this purpose such as for example thin sheets of cpet polyester or other temperature resistant plastic sheet film the provision of such a laminated interior layer in the pans of the present invention is optional since it has been found that suitable ease of release of finished baked goods can be achieved by greasing and flouring the interior walls of a paper baking pan in a manner well known to cooks and bakers it is also contemplated that the surface of the molded paper fiber pan can incorporate fiber sizes or starch fillers which will produce a smooth surface and one that does not require greasing or flavoring for release of the baked goods the following examples will serve to further illustrate the production of and improvements in the use of the baking pan of this invention a heat controlled baking pan of this invention is produced by a molded paper fiber process comprising the following steps a mass of paper fiber is deposited on the screen surface of a female wet mold by submerging in a slurry of dispersed paper fibers and drawing the slurry through the wet mold until the thickness of said fiber of approximately 0 080 to 0 105 inch has been deposited thereon the wet mold is withdrawn from the slurry allowed to drain of free water and positioned beneath a complementary.
