PROBLEM TO BE SOLVED: To provide a multilayer film that is good in fabricability, and excellent in low-temperature heat sealability and rigidity.SOLUTION: A low-temperature heat sealable high rigidity multilayer film is obtained by laminating a heat seal layer composed of polyolefin-based resin on one side of an intermediate layer containing a polypropylene-based resin composition comprising the following components (a) to (c). The component (a): propylene-α-olefin random copolymer by 60 to 90 wt.%, the component (b): alicyclic hydrocarbon resin selected from petroleum resin, terpene resin, rosin-based resin, coumarone-indene resin and hydrogenated derivatives thereof by 10 to 40 wt.%, the component (c): nucleating agent comprising a compound represented by the formula (1) by 0.01 to 0.5 pts.wt. |
