PROBLEM TO BE SOLVED: To provide a multilayer film having sufficient moisture-proofness, transparency and heat sealability.SOLUTION: There is proposed a multilayer film including a resin layer (I) containing an ethylene-based polymer (A), a nucleating agent (B), and an olefin-compatible resin (C) comprising one sort or two sorts or more of combinations selected from the group consisting of a petroleum resin, terpene resin, coumarone-indene resin, rosin-based resin, and hydrogenation derivatives thereof, and other layers except the resin layer (I), wherein the resin layer (I) satisfies the following conditions (i) to (iv): condition (i): the density is 0.940 g/cmto 0.960 g/cm; condition (ii): the crystal melting heat quantity (&Dgr;Hm) is 120 J/g to 160 J/g; and condition (iii): the storage shear modulus of elasticity (G') at 200°C is 2,000 Pa to 50,000 Pa. |
