Abstract
PURPOSE: To prepare a laminated film for agricultural use, having excellent heat retaining properties, transparency, weather resistance, toughness, anti-fogging properties, applicability as green house glazing, handleability, and dust-proofing properties, by laminating three layers of specific polyolefin films wherein the adjacent layers are different each other.
CONSTITUTION: A laminated film composed of (A) an outer layer composed a low density polyethylene having a density of ≤0.925, (B) an intermediate layer composed of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 14W28 wt% and/or an olefin-vinyl alcohol copolymer having a degree of saponification of ≥80%, and (C) an inner layer composed of a low density polyethylene and/or an ethylene-vinyl acetate copolymer. The ratios of the thickness of (A)/(B)/(C) are 5W30%/90W40%/5W30%, and the total thickness is 50W200 microns.
