PROBLEM TO BE SOLVED: To obtain a resin compsn. for a sealant film excellent in low temp. heat sealability, heat seal strength, blocking resistance or the like and the sealant film. SOLUTION: A resin compsn. for a sealant film consists of (A) 65-35 wt.% straight chain low density polyethylene, (B) 45-15 wt.% ethylene/α-olefin random copolymer with a density of 0.850-0.900 g/cm3 and a melt flow rate(MFR) measured under a condition of 190 deg.C and 2.16 kg load of 0.1-50 g/10 min and (C) 5-40 wt.% butene/α-olefin random copolymer with a 1-butene content of 50-99 mol.% and a melt flow rate(MFR) measured under a condition of 190 deg.C and 2.16 kg load of 0.1-20 g/10 min and the sealant film is obtained by laminating the sealant layer comprising this resin compsn. on an olefin base material layer.
