<p>Disclosed is a highly translucent film material having a good daylighting property in addition to a hazardous-ultraviolet-ray-shielding property and an infrared-ray-shielding property suitable for use in film structures such as tents for creating a summer-like environment for swimming pools, greenhouses, compost depots, tent storehouses, medium- and large-sized tents, truck covers, and sun-shade tents. The film material includes a front-surface infrared-reflecting resin layer and a back-surface thermoplastic resin layer formed on a base fabric composed of a fibrous material. At least the front-surface infrared-reflecting resin layer contains 0.5 to 5 mass% of interference mica particles and one or both of the front-surface infrared-reflecting resin layer and the back-surface thermoplastic resin layer contain 0.3 to 3 mass% of at least one selected from ultrafine titanium oxide particles and ultrafine zinc oxide particles. The film material as a whole has a visible light transmittance (Japanese Industrial Standard (JIS) Z8722) of 40% to 80%.</p> |
