The problem of the present invention is to provide a remarkably strong container made of paper which is constituted by a resin film and paper, and is used for baking or steaming confectionery, bread, etc., or for storing food, etc., wherein the resin film has an increased shape retention property. A paper container is formed by molding a laminated film in which a stretched resin film and paper are laminated, using a male die and a female die, and after the molding, heating the film at a temperature about 80 degrees to 190 degrees which is equal to or lower than the melting point of the stretched resin film for 80 seconds to 30 minutes inclusive. |
