PURPOSE:To make the desired photo-shielding according to the intended use by forming the film of a film structure from a sheet of fluoric resin prepared by applying a fluoric resin later to the surface of a fabric consisting of organic or inorganic fibers. CONSTITUTION:The film of a film structure which can expand with a gas to be absorbed and released, is formed from fluoric resin sheets 1, 1 prepared by applying a fluoric resin layer to at least one of the surfaces of a fabric consisting of organic fibers and/or inorganic fibers. Therein the filler content of the fluoric resin layer, the type of the filler, and the tickness of the layer are allowed to appear in different values to generate various combinations, and thereby the color and hue are differed any as desired on the two surfaces of the sheet 1, and also the sheet 1 is given any desired light reflectance and photo-transmissivity. The two sheets 1 are fusion attached by heat while their fluoric resin layers face each other, and joining jigs 4, 4 having an injection/ exhaust port 5 are mounted at the shorter edge member. |
