PROBLEM TO BE SOLVED: To provide an agricultural polyolefinic resin film excellent in all of transparency, heat insulating properties, anti-fogging lasting properties and toughness. SOLUTION: An agricultural multilayered film is a three-layered laminated film and the inner and outer layers thereof mainly comprise an ethylene/vinyl acetate copolymer resin with a vinyl acetate content of 1-10 wt.% and the intermediate layer comprises a compsn. prepared by adding 1-20 pts.wt. of an inorg. compd. containing one atom selected from Mg, Ca, Al, Si and Li to 100 pts.wt. of compsn. prepared by mixing 5-60 wt.% of an ethylene/α-olefin copolymer resin obtained by copolymerization using a metallocene catalyst and having characteristics such that an MFR is 0.1-10 g/10 min, density is 0.88-0.915 g/cm3 and Mw/Mn is 1.5-3.5 with 95-40 wt.% of an ethylene/vinyl acetate copolymer resin with a vinyl acetate content of 10 wt.% or more.
