(57) Abstract: The inflation multilayer film of the present invention comprises an inner layer, at least one intermediate layer and an outer layer, wherein the inner layer has a density of 0. 920 to 0.935 g / cm 3 , MFR 0.5 to 2.5 g / 10 minutes Metallocene linear low-density polyethylene and a composition containing a specific ratio of an antistatic agent, and the intermediate layer, density 0.950~0.965g / cm 3, M FR 0.3 to 6.0 g / 10 minutes high density polyethylene, the outer layer has a density of 0.918 to 0.935 g / cm 3 and MFR 0.5 to 5.0 g / 10 minutes metallocene linear low density polyethylene. , A slip agent and a specific ratio, and the ratio [t 1 / t 0 ] of the thickness of the inner layer (t 0 ) to the thickness of the entire intermediate layer (t 1 ) is 0.3 to 2 And the ratio (t 2 / t 0 ) of the thickness (t 0 ) of the inner layer to the thickness (t 2 ) of the outer layer is 0.5 to 1. 5 The above-mentioned multilayer film has high rigidity and stiffness even with a thin thickness of, for example, about 70 μm, and has high mechanical strength such as tear strength and start-in impact strength, and has high gloss. |
