ンアクリル酸重合体が使用されている。[Prior art] Conventionally, most of the raw material used for manufacturing laminate tubes is
It is constructed by combining about 7 to 8 layers of polyethylene, ethylene acrylic acid polymer, aluminum foil, etc. Most of the laminate tubes are used for toothpaste, and ethylene acrylic acid polymer is used as an adhesive layer between aluminum foil and polyethylene.

ある。[Problems to be solved by the invention] Toothpaste contains fragrances such as peppermint and spearmint, and although the conventional laminate tubes mentioned above have some degree of resistance to these fragrances, it is difficult to use them for pharmaceutical use. If used, delamination or oxidation of the aluminum foil may occur. This is because some pharmaceutical products contain menthol, salicylic acid, etc., which have a different effect than the above-mentioned peppermint, spearmint, etc., and impair the adhesive strength of the ethylene acrylic acid polymer.
この発明は収納物がメントール、サリチル酸等を含む薬
