PROBLEM TO BE SOLVED: To provide an agricultural covering film excellent in tenacity and toughness, easily matching with the shapes of the water-draining gut, etc., of a water-supplying bed, i.e. excellent in matching property, without generating wrinkles on extending it, further not having the melt-adhesion of the films each other, excellent in molding stability and exhibiting less moss-generation. SOLUTION: This agricultural covering film is characterized by laminating a layer obtained by blending 5-50 wt.% white pigment with an ethylene/α-olefin copolymer obtained by a polymerization using a single site catalyst and having 0.3-5.0 melt flow rate and 0.850-0.910 g/cc density, with a layer obtained by blending 1-20 wt.% black pigment with an ethylene/α-olefin copolymer obtained by the polymerization using a single site catalyst and having 0.3-5.0 melt flow rate and 0.850-0.910 g/cc density, so as to constitute 10 white layer, 11 black layer and 12 white to a thin black layer laminate. |
