To provide a method for producing agricultural polyolefin resin film by which antifog agricultural film made via inflation forming, obtained by applying antifog coating on polyolefin resin film and having broad width creases is effectively prevented from causing breakage of the creases.

The method for producing agricultural polyolefin resin film comprises forming antifog coating comprising inorganic colloid sol and a thermoplastic resin binder on the outer peripheral surface of polyolefin resin film formed into a cylindrical and flat shape via inflation forming and having creases at its both edges. The method comprises a process of almost uniformly forming the antifog coating. The thickness of the antifog coating of the polyolefin resin film in the vicinity of at least one side crease is about 0.5-1.8 times the average thickness of the antifog coating at the part other than the vicinity of the crease.
