AGRICULTURAL FLUORINE-CONTAINING MULTILAYER FILM, METHOD OF PRODUCING THE SAME AND AGRICULTURAL COVERING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an agricultural fluorine-containing multilayer film and an agricultural covering material which have weather resistance and long-term spreadability equal to conventional fluorine film, and particularly has excellent drip-proofness.SOLUTION: There is provided the multilayer film which contains: a protective layer (A) composed of at least 60 to 95 pts.mass of polyvinylidene fluoride-based resin and 40 to 5 pts.mass of polymethacrylic acid ester-based resin; an ultraviolet absorption layer (B) that contains ultraviolet absorber, and is composed of 0 to 40 pts.mass of polyvinylidene fluoride-based resin and 100 to 60 pts.mass of polymethacrylic acid ester-based resin; an adhesion layer (C); and a substrate layer (D) composed of polyolefin-based resin in this order, and in which a drip-proof layer (E) having silica as a main component is formed on a surface of the substrate layer (D) side having a surface roughness expressed by arithmetic average roughness Ra of 0.8 to 3.2 μm.SELECTED DRAWING: None
