The present invention provides a laminated film which has suitable easy-opening properties and high sealing strength even at high temperatures.n n n The present invention can achieve suitable easy-opening property and high sealing strength at high temperature by the following: a laminated film, which is a laminated layer having a surface layer (A), an intermediate layer (B), and a sealing layer (C) A film in which the surface layer (A) and the sealing layer (C) contain a polypropylene-based resin as a main component, the intermediate layer (B) contains a polypropylene-based resin (b1) and a polyethylene-based resin (b2), and the intermediate The content of the polypropylene resin (b1) in the resin component contained in the layer (B) is 40 to 70% by mass, the content of the polyethylene resin (b2) is 30 to 60% by mass, and the intermediate layer (B) The thickness is 15% or less of the total thickness of the laminated film, and the thickness of the sealing layer (C) is 15% or less of the total thickness of the laminated film. |
