The instant invention generally provides polymer inorganic clay composite comprising a molecularly self-assembling material and an inorganic clay, and a process of making and an article comprising the polymer inorganic clay composite. The apparatus includes a fluid passageway, at least one source of irradiation, and curved reflecting troughs for reflecting irradiation onto the fluid passageway. The system presents the image from one of the image sources, containing background image information, at a distance from the viewer which is greater than the distance from the viewer to the other image presented from the other image source, which contains foreground image elements. Acoustic radiation generated by the acoustic radiation generator is transmitted through each reservoir to an analyzer. The easily peelable film has excellent heat resistance, flexibility, and transparency and further a broad temperature range for low temperature welding at which peelable partition walls can be formed.
