Manufacturing method of agricultural film and film for agricultural use

摘要

[Problem] To provide a method for manufacturing an agricultural film which enables the production of an agricultural film formed with an antifog coating film, the agricultural film made less prone to crack formation at a crease thereof and achieving excellent durability. [Solution] A method for manufacturing agricultural film includes: a flattening step of flattening out an elongate tubular film into a band body 19 having a constant width; an antifog coating film forming step of forming an antifog coating film on an outer periphery of the band body 19; a cutting step of cutting one of a lower film 23 and an upper film 21 of the band body 19 after the drying of the antifog coating film by longitudinally forming a slit 37 at the center of a width thereof; a folding step of folding the band body 19 along the slit 37 into four layers in a manner to place the slit 37 inside; and a winding step of winding the fourfold band body 19 into a roll.
