PROBLEM TO BE SOLVED: To provide a multi-layer inflation film, which has matte appearance equal to a matte film formed by T-die method-embossing processing, and which is provided with appropriate rigidity, strength, and seal properties for a bag basic function, and which is easy of bag processing, and excellent in economy. SOLUTION: An inflation film is composed of at least three layers comprising an outer layer composed of PP resin, an inside layer composed of a mixture comprising one of LDPE, LLDPE, or EVA, and PP resin, and an interlayer composed of one of LDPE, LLDPE, or EVA, abutting against the inside layer. The PP resin contains 30-60 wt.% EP rubber, where ethylene component is at least 20 wt.%, and has 40-70% crystallinity index, 0.885-0.915 g/cm<3> density, and 0.1-5 MFR. |
