Additional planar sheets or embossed sheets may be added as desired in order to achieve the desired flexural stiffness and thermal resistance. Such containers being in the form of cups, plates, bowls or trays and formed by providing the substantially planar sheet of paperboard material, forming the planar sheet of paperboard material into a container shell, providing a first embossed sheet of paperboard material having raised portions and adhering the raised portions of the first embossed sheet of paperboard material to the planar sheet of paperboard material, providing a second embossed sheet of paperboard material having raised portions and adhering the raised portions of the second embossed sheet of paperboard material to the first embossed sheet of paperboard material.
