PROBLEM TO BE SOLVED: To produce a polyolefin resin film for agricultural purposes that has an improved fusing behavior of the rolled-up film without adverse effect on the film transparency, shows a good adhesion when it is coated, and excellent in resistance to weather and anti-fogging properties and can be used in the extended form for a long period of time. SOLUTION: The objective polyolefin resin film for agricultural purposes is characterized by forming a coating layer comprising the following polymer product (A) on the outer face of a green house, when it is extended: the polymer product (A) is obtained by allowing (a) an olefinic resin bearing at least one functional group in one molecule to react with (b) a radically polymerizable monomer bearing a functional group reactive with the functional group in the resin (a) to form a radically polymerizable olefin resin (c), further copolymerizing (d) a copolymerizable monomer mixture including an alkyl (meth)acrylate as an essential component with the resultant radically polymerizable olefin resin (c).
