PROBLEM TO BE SOLVED: To provide a film for the facility gardening of good resistance, sprayproof properties and toughness and also superior spread workability on which strength of a fold is hard to be lowered with the passage of time. SOLUTION: A slit is formed along the length direction of a cylindrical film formed by the inflation method, and when the cylindrical film is released and opened from the slit and spread on a facility gardening greenhouse, the inner skin of an inner layer A of the cylindrical film is positioned on the inner face side of the facility gardening greenhouse, while the outer skin of an outer layer C of the cylindrical film is positioned on the outer face side of the facility gardening greenhouse and an intermediate layer B is formed between the inner layer A and the outer layer C on a film of multilayer structure used for the facility gardening, and a main component of a composition constituting the outer layer C of the cylindrical film is an ethylene-α-olefin copolymer (c1) of the 0.88-0.96 g/cm3 density (dc1 or an ethylene homopolymer (c2) of the 0.91-0.93 g/cm3 density (dc2).
