PURPOSE: To obtain excellent heat insulation, blocking resistance and transparency by an agricultural laminated film in which a front surface layer contains olefin composition which contains specific wt.% of lithium-aluminum composite hydrixide salt represented by the general formula (I) of a laminated film and an olefin polymer and an inner layer contains olefin copolymer. CONSTITUTION: A laminated film comprises a front surface layer formed of olefin composition containing 1 to 25wt.% of lithium-aluminum composite hydroxide salt represented by the general formula (in the formula, X is inorganic or organic anion, n is valence number of anion X and m is 3 or less) and 75 to 99% of olefin polymer A, and an inner layer formed of olefin copolymer B. An agricultural laminated film contains olefin polymer A having ethylene sole polymer having a density of 0.91 to 0.935g/cm<3> , ethylene-α-olefin copolymer having a density of 0.89 to 0.935g/cm<3> and/or ethylene-vinyl acetate copolymer having a density of 0.92 to 0.95g/cm<3> and less than 20wt.% of vinyl acetate content.
