PROBLEM TO BE SOLVED: To provide a laminated tube that is suitable for storage of an oxidation hair dye or the like while avoiding a color change. SOLUTION: The laminated tube includes a cylindrical body portion "A" formed in a cylinder shape by joining both side parts of a laminated film for the body portion, and a head portion "B" that has a shoulder part and a sealed spout part, and is continuously provided at the cylindrical body portion. The body portion laminated film includes at least a heat seal film (I), a gas-barrier film D, a metal thin film, and a heat seal film (II), from the innermost layer in the order. Each layer is laminated with an adjacent layer via a melting extrusion layer made of a thermal-fusion resin. The thickness of the metal thin film is 15 to 50μm. A gas-barrier tape is laminated on the inside of the tube of the joined part to form a back bonded part P. COPYRIGHT: (C)2011,JPO&INPIT |
