PROBLEM TO BE SOLVED: To provide an inflation film for a double-bag package which hardly causes blocking between inner layers even if the double-bag is hot-filled with a food or the like upon making the double-bag package. SOLUTION: The inflation film for the double-bag package consists of an outer layer 23 made of a resin having a heat sealability, an intermediate layer 22 made of a polyamide resin, and an inner layer 21 made of a low-density polyethylene resin (LDPE). The Vicat softening point of the LDPE composing the inner layer 21 is determined to be 110°C or higher and 125°C or lower, and the density of the LDPE is determined to be higher than 0.930 g/cm<SP>3</SP>and 0.940 g/cm<SP>3</SP>or lower.
