Zusammenfassung:An agricultural film is provided to secure excellent durability on clarity and drop-preventing properties by comprising a first layer comprising thermoplastic resin and a second layer comprising an ethylene/alpha-olefin copolymer, ethylene/vinyl acetate copolymer and non-ionic surfactant. An agricultural film comprises a first layer and a second layer, wherein the first layer comprises thermoplastic resin and constitutes one surface of the film and the second layer is adjacent to the first layer and comprises a component(A), component(B) and component(C). The content of the component(B) in the second layer is 20 to 900 parts by weight per 100 parts by weight of the component(A), and the content of the component(C) is 0.01 to 5% by weight of the total weight of the component(A), component(B) and component(C). The component(A) is an ethylene/alpha-olefin copolymer which contains an ethylene-derived constitutional unit and C3-20 alpha-olefin derived constitutional unit and has a melt flow rate from 0.01 to 5 g/10 min and an activation energy of flow of 35 kJ/mol or more; the component(B) is an ethylene/vinyl acetate copolymer which contains an ethylene-derived constitutional unit and vinyl acetate derived constitutional unit and has a melt flow rate from 0.01 to 5 g/10 min and a vinyl acetate content of from 3 to 20% by weight; and component(C) is a non-ionic surfactant.
