、構成中に紙層が存在しない積層材が開発されている。Tube containers for storing fluid or semi-fluid substances such as toothpaste, cosmetics, and food pastes are cylindrical containers made of laminated materials with physical properties such as appropriate stiffness, water resistance, and gas barrier properties. The body includes a body, a closure member having a shoulder and a neck and engaged with the upper open end of the body, and a cap detachably attached to the neck of the closure member. In order to provide water resistance and facilitate molding, laminated materials without a paper layer have been developed in recent years.

せてしまうという問題があった。However, in the above-mentioned laminated materials, the base color of the laminated materials is determined by the color of the ink used as the printing layer and the color of the concealing resin layer.For example, the base color of the laminated materials is white, milky white, cream, etc. There was no laminate material with a metallic luster reminiscent of extruded tubes made by the company. In addition, if the metallic luster of the aluminum foil as a barrier layer is used as the background color without using a concealing resin layer, the flatness of the metallic lustrous surface deteriorates due to minute irregularities and wrinkles that occur on the aluminum foil during the manufacturing stage, and vice versa. There was a problem in that the image of the extruded tube deteriorated.

The resulting laminated material has a base color with a matte metallic luster or a hairline metallic luster. Since the metal thin film 7 is formed on a biaxially stretched resin film, the occurrence of unevenness and wrinkles on the metal thin film 7 during the manufacturing stage is significantly less than when metal foil is used, and therefore the surface properties are improved. A good and beautiful metallic luster background color can be obtained.
