PROBLEM TO BE SOLVED: To provide a laminated film excellent in easy openability, low temperature heat sealability and steam barrier properties. SOLUTION: The laminated film comprises at least two layers, that is, a resin composition layer, which contains 50-80 pts.mass of a propylene/α-olefin random copolymer (a) with anα-olefin content of 3-10 mass % and a melt flow rate of 5-35 g/10 min, 5-20 pts.mass of high density polyethylene (b) with a melt flow rate of 1-25 g/10 min, 5-20 pts.mass of linear low density polyethylene (c) with a melt flow rate of 1-10 g/10 min and 10-40 pts.mass of a butene resin (d) [(a)+(b)+(c)+(d)=100 pts.mass], and a propylene resin layer containing a propylene resin (e) with a melt flow rate of 1-10 g/10 min. The sealant film using the laminated film and the package using them are also disclosed.
