摘要:
PROBLEM TO BE SOLVED: To provide an agricultural multilayered film having good toughness and excellent flexibility and excellent in airtightness of a greenhouse, workability and transportation storage efficiency. SOLUTION: In an agricultural multilayered film constituted of at least an inner layer A, an intermediate layer B and an outer layer C, the inner layer A is constituted of a compsn. based on an ethylene/vinyl acetate copolymer polymerized using a single site catalyst and having a density (da) of 0.88-0.92 g/cm3 and the intermediate layer B is constituted of a compsn. based on a thermoplastic resin (b) of which the tensile modulus as a single-layered film is larger than that of a single-layered film comprising the ethylene/α-olefin copolymer (a) and containing 1-10 wt.% of an anti-fogging agent and the outer layer C is constituted of a compsn. based on an ethylene/α-olefin copolymer (c) polymerized using a single site catalyst and having a density (dc) of 0.88-0.92 g/cm3.
