摘要:
PROBLEM TO BE SOLVED: To provide agrochemical-resistant polyolefin-based agricultural film having good resistance to medical agents, excellent in a heat-retaining property and mechanical physicality and retaining favorable defogging drippability. SOLUTION: The agrochemical-resistant polyolefin-based agricultural film is obtained by laminating the following layers (A), (B) and (C) in this order: a layer (A) comprising resin components containing polyethylene resin (a) and adhesive resin (b) at a weight ratio a/b=90/10 to 40/60; the layer (B) comprising resin components containing an ethylene-vinyl acetate copolymer (c) and an ethylene-vinyl acetate copolymer resin (d) at a weight ratio c/d=90/10 to 50/50; and the layer (C) comprising resin components containing mainly of ethylene-acetate-vinyl copolymer (e). The layers are laminated in the order of (A)/(B)/(C). A hindered amine light stabilizer at 0.02-5 pts.wt. is formulated with 100 pts.wt. of the resin components constituting the film in at least one layer of the layers (A), (B) and (C).
