PROBLEM TO BE SOLVED: To provide a multi-layered film for a laminate tube excellent in gas barrier properties, especially in water vapor barrier properties in a wet condition, and excellent in disposal properties after usage, and to provide a laminate tube using the multi-layered film.SOLUTION: In a multi-layered film for a laminate tube, at least a base material layer, a gas barrier layer and a sealant layer are sequentially laminated. The base material layer is formed of a single linear low-density polyethylene resin layer or a laminate including the linear low-density polyethylene resin layer as a main component, the gas barrier layer is formed of a co-extrusion film in which an ethylene vinyl alcohol copolymer resin layer is laminated, and the sealant layer is a three layer film which is prepared by co-extruding the linear low-density polyethylene resin layer, a high density polyethylene resin layer and the linear low-density polyethylene resin layer in this order. |
