PROBLEM TO BE SOLVED: To provide a heat shielding agricultural film having strength and weather resistance, capable of sufficiently transmitting sunlight, sufficiently shielding heat rays from sunlight, and maintaining antifogging / flicking property. The heat-insulating agricultural film of the present invention contains 100 parts by weight of a thermoplastic resin, 0.1 to 10 parts by weight of mica whose surface is coated with titanium oxide, and the surface is coated with titanium oxide. The mica has a 10% particle diameter of 3 μm or more and a 90% particle diameter of 80 μm or less, a mica coverage of titanium oxide of 35 to 70%, and a particle size of 5 to 100 parts by weight in an aqueous medium. 0.1 to 20 parts by weight of chain silica colloidal particles formed by binding 40 nm of silica colloidal particles in a chain of 40 to 300 nm, and 0.1 to 0.1 part of polyethylene oxide having a viscosity average molecular weight of 50,000 to 1,500,000. An anti-fogging droplet layer formed from an anti-fogging droplet agent having a pH of 7 to 12 in which 10 parts by weight is dispersed is formed on the surface. [Selection figure] None |
