PROBLEM TO BE SOLVED: To provide an agricultural polyolefin film that has excellent transparency, durability, heat insulation and resistance to chemicals, inhibits weather resistance and film transparency from being deteriorated under acidic conditions caused by, e.g. acid rain or use of acidic agrochemicals and additionally can retain these excellent properties. SOLUTION: This agricultural polyolefin film comprises at least two layers, namely (a) a polyolefin resin layer including at least one of hindered amine bearing at least two piperidine ring structures represented by formula (1) [wherein R1 is a functional group of one or more carbon atoms and at least one or more methylene groups or a compound (may be oligomers or polymers) with an average molecular weight of >=1,000] and (b) a polyolefin resin layer including an infrared-absorbing agent of a metal compound hydroxide salt constituted with, as an active ingredient, of metal components including at least aluminum and lithium and at least one of anion. In this agricultural film, the resin layer (a) and the resin layer (b) can be used in a single layer or in multiple layers.
