PROBLEM TO BE SOLVED: To obtain a non-polyvinyl chloride laminated film which is good at flexibility, processability, and the balance of strength, and does not generate harmful gas in incineration. SOLUTION: In a laminated film constituted at least from both outer layers and an intermediate layer, the intermediate layer consists of a block copolymer mainly containing at least one vinyl aromatic hydrocarbon block and at least one block mainly consisting of a conjugated diene or its hydrogen adduct, and both outer layers consist of a polyethylene resin. The ratio of the total thickness of both layers to that of the intermediate layer is 1:0.2-50. |
