(57) [Summary] [Objective] To provide an agricultural synthetic resin film having excellent anti-fog and anti-fog properties suitable for covering materials such as agricultural houses for two years or more from the initial stage immediately after spreading. (A) Sorbitan and C24 as antifogging agent Esters of higher fatty acids (montanic acid wax), or esters of glycerin and montanic acid wax, and / or their alkylene oxide adducts and / or esters of polyoxyalkylenes and montanic acid wax, the main constituent being -34. (B) A fluorine-based surfactant is used as an antimist agent, and these are kneaded with a film resin such as a vinyl chloride resin, polyethylene, or ethylene-vinyl acetate copolymer, and a film is formed to obtain an agricultural synthetic resin film. The agricultural synthetic resin film further contains (c) an ester of sorbitan and a higher fatty acid having 12 to 22 carbon atoms, an ester of glycerin and a higher fatty acid having 12 to 22 carbon atoms, or an alkylene oxide adduct thereof. Improves the anti-fog performance. |
