发明名称 AGRICULTURAL MULTILAYERED FILM
摘要 PROBLEM TO BE SOLVED: To provide an agricultural polyolefinic multilayered film especially excellent in initial transparency, opening properties and long-term light permeability (dust-proof properties) and excellent in various capacities such as anti- fogging lasting properties, mechanical strength or the like. SOLUTION: In an agricultural multilayered film, at least one layer comprising a resin compsn. containing an ethylene/α-olefin copolymer resin (A) obtained by copolymerization using a metallocene catalyst and a high density polyethylene resin (B) in a wt. ratio (A)/(B) of 99/1-70/30 and compounded with 60 wt.% or more of these resins in total is constituted on an outer layer and/or an inner layer. The ethylene/α-olefin copolymer resin (A) has characteristic values such that (a) a constitutional unit derived from anα-olefin in an ethylene/3-10Cα- olefin copolymer resin is 30 wt.% or less, (b) a melt flow rate is 0.1-10 g/10 min, (c) a density is 0.88-0.930 g/cm3 and (d) a mol.wt. distribution (wt. average mol.wt./number average mol.wt.) is 1.5-3.5.
