PROBLEM TO BE SOLVED: To provide a monolayer or multilayer agricultural film having excellent transparency, heat retaining properties, mechanical strengths and light resistance over a long period without being influenced by the acidic environment such as acid rain, spraying of agricultural chemicals or fumigation of sulfur. SOLUTION: The agricultural film has at least one-layer olefinic resin layer in which 0.01-10 wt.% NOR type hindered amine light stabilizer, 1-25 wt.% heat-retaining agent and 0.01-5.0 wt.% anti-fogging agent are formulated. In this case, an ordinary hindered amine light stabilizer can combinedly be used with the NOR type hindered amine light stabilizer. COPYRIGHT: (C)2004,JPO
