<p>PROBLEM TO BE SOLVED: To control the speed of temperature rise at every food on heating it by a microwave oven and have subdivided food at an appropriate temperature, by providing a conductive cover having a specified surface specific resistance at the outer periphery of a plastic container body. SOLUTION: This packing container preferably used for subdividing packaging containers of food required to control the microwave heat in a microwave oven or the like, is provided with a conductive lining with the surface specific resistance of 10<2> (Ω/square), of which outer peripheral shape is formed by curves with 3m/m or larger radius of curvature or the combination thereof, at a part of the plastic container body face or the whole face thereof. The outer peripheral shape of the conductive lining is circular or elliptic and the diameter or the larger or shorer diameter are set to range 6-50cm. Materials chiefly made of metal like aluminum, inorganic materials like carbon black, or various conductive polymers, etc., can be used as the constituent of the conductive lining material.</p> |
