PROBLEM TO BE SOLVED: To provide a laminated film suitable as a packaging material for food and medical treatment, to provide a sealant film excellent in easy opening properties, low temperature heat sealability (the stability of heat seal strength) and steam barrier properties and to provide the laminated film, the sealant film, a laminate, a package or the like not generating whiteness and a feathering phenomenon and also excellent in appearance. SOLUTION: The laminated film comprises at least two layers, that is, a resin composition layer, which includes 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 straight chain low density polyethylene (b) with a melt flow rate of 1-10 g/10 min and 10-40 pts.mass of a butene resin (c) [(a)+(b)+(c)=100 pts.mass], and a polypropylene resin layer including a propylene resin (d) 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.
