The one shown in Publication No. 10847 is known. What is described in this publication is a method in which an alkali-resistant and acid-resistant synthetic resin film is laminated on the inner surface of an aluminum foil via an adhesive, and a flexible and strong synthetic resin layer is formed on the outer surface of the aluminum foil. It is a flexible laminated body that is laminated to form a cylindrical tube body.

き層間剥離を起す欠点がある。 However, in the laminated material described in the publication,
Volatile components such as aromatic oils and fragrances in the contents gradually permeate the alkali-resistant and acid-resistant synthetic resin film laminated on the inner surface of the aluminum foil, and the aluminum foil and the alkali-resistant and acid-resistant As a result, delamination occurs between the aluminum foil and the alkali-resistant and acid-resistant synthetic resin film. Therefore, it has been proposed to use an acid polymer that can directly react with the metal foil as an adhesive between the metal foil and the alkali-resistant and acid-resistant synthetic resin film, but even in this case, it is not always sufficient. There is a drawback that the above-mentioned delamination may occur depending on the contents.

固化等の弊害を生ずるおそれもある。 Furthermore, as mentioned above, the volatile components that permeate through the alkali-resistant and acid-resistant synthetic resin film gradually penetrate the pinholes of the aluminum foil on its outer surface, as well as the flexible laminate on its outer surface. As a result, there is a risk that the contents may be permeated, resulting in harmful effects such as loss of aroma or solidification of the contents during storage.

The present invention was completed by discovering that a laminate material that can be stored can be obtained. The present invention will be explained in more detail below using the drawings.

保存に於ても内容物の変化は殆んど生じない。 That is, in the laminated material according to the present invention, a gas-shielding resin layer and a polyolefin resin layer are laminated on the inner surface of a metal foil, and the permeation of volatile components in the contents is restricted by the polyolefin resin layer. At the same time, the gas shielding layer formed on the outer surface completely prevents the volatile components from permeating into the anchor coating agent interposed between the metal foil and the gas shielding layer. Therefore, there is no risk of delamination between the metal foil and the coextruded coating layer. Therefore, the contents hardly change even during long-term use or storage.

When extruding the contents, the laminated material can be given appropriate flexibility and an appropriate tear-proof strength. Another advantage is that there is no risk of things leaking.

の容器に広く適用することができる。 As described above, when the laminated material according to the present invention is used as an extrusion tube, volatile components of the contents do not permeate, and therefore, the material can be used as a tube for extrusion, thereby preventing the permeation of volatile components of the contents between the metal foil and the coextrusion coating layer on the inner surface thereof. It does not cause delamination between layers, and there is no risk of deterioration of the contents even after long-term use or storage, and it can be widely applied to containers for toothpaste, cosmetics, fragrances, and other items.
