PROBLEM TO BE SOLVED: To provide an inexpensive agricultural laminated film which has sufficient tear strength and impact strength when the film is used, and exhibits a proper photodecomposition property and a microbial decomposition property of the film when scrapped.SOLUTION: In the agricultural laminated film which is an agricultural laminated film formed by piling three layers of an A layer/B layer/A layer in an increasing order, the A layer includes a polyethylene resin having the following properties of (1) and (2): (1) MFR: 0.5 to 10 g/10 minutes and (2) density: 0.910 to 0.935 g/cm3, and an oxidative decomposition agent showing activeness when exposed to light and/or heat. The B layer is formed of a composition containing an aliphatic polyester resin. the layer thickness ratio between and among the A layer, B layer and A layer is 1:1:1 to 1:10:1.COPYRIGHT: (C)2012,JPO&INPIT【課題】フィルムの使用時は十分な引裂き強度や衝撃強度を有し、廃棄時には適度なフィルムの光分解性及び微生物分解性が発揮される安価な農業用積層フィルムを提供する。【解決手段】A層/B層/A層の三層からなる農業用積層フィルムであって、A層が下記(1)及び(2)の性状を有するポリエチレン系樹脂と光及び又は熱により活性を示す酸化分解剤を含有し、B層が脂肪族ポリエステル系樹脂を含む組成物からなり、かつ、A層:B層:A層の層厚み構成比が1:1:1~1:10:1であることを特徴とする農業用積層フィルムによって提供する。(1)MFR;0.5~10g/10分(2)密度;0.910~0.935g/cm3【選択図】なし
