あつた。Problems to be Solved by the Invention In this conventional matting method, two aluminum alloy foils are stacked and rolled, and the surface of the two aluminum alloy foils in contact with the rolling roll becomes a glossy surface. Since the surface of the aluminum alloy foil that is mated is a matte surface, there is a drawback in that only an aluminum alloy foil having a glossy surface (non-matte surface) on one side and a matte surface on the other side can be produced.

検査ミスを生じるおそれがあるという欠点があつた。When the above-mentioned one-sided matte aluminum alloy foil is used as a package containing this tablet, characters and designs are printed on the aluminum alloy foil in advance, and after packaging, the characters, patterns and packaging of the packaged product can be judged by the operator's eyes. During the inspection, the diffuse reflection of light on the glossy surface that is not matted on one side is too strong, and it is difficult for the operator to see the package, and the operator's eyes are easily tired, which may cause eye damage. Further, there is a drawback that an inspection error may occur because it is difficult to see.

It was Further, among the above-mentioned conventional matting methods, the method of applying a matting agent to the glossy surface of an aluminum alloy foil requires a matting agent and requires a matting agent coating step, which is costly and troublesome. There was a drawback.

手間がかからずにアルミニウム合金箔を造ることを目的
としたものである。The present invention eliminates these drawbacks of the conventional method for producing a matte aluminum alloy foil, enables matte printing on both sides with a matte surface on both sides, and is relatively inexpensive and hassle-free. The purpose is to make an aluminum alloy foil.

金箔を製造する方法である。Means for Solving the Problems The present invention is provided between two outer foils made of aluminum alloy foil (including aluminum foil) having a hardness of about 65 HV to about 75 HV and a hardness of about 10 HV to about 10 HV than the outer foil. This is a method of producing a double-sided matte aluminum alloy foil by rolling with an intermediate foil of 20 HV small aluminum alloy foil (including aluminum foil) interposed.
硬さの単位「HV」はJIS,Z2251微小硬さ試験に準じて
下記測定条件で硬度測定した｛HV（20g）｝。The hardness unit "HV" was measured according to JIS, Z2251 microhardness test under the following measurement conditions {HV (20g)}.

It is not preferable because scratches are likely to occur on the intermediate foil, and when it is higher than 75 HV, the ductility of the outer foil is poor and the foil during rolling is easily broken, which is not preferable. Furthermore, if the intermediate foil is less than 10HV in hardness than the outer foil, the outer foil cannot protect the inner foil, and a double-sided matte aluminum foil with an irregular roughness and stable appearance can be produced. Because it is not possible,
On the other hand, if it is more than 20 HV, the difference in deformation between the inner and outer aluminum alloy foils during rolling is too large, which causes distortion or wrinkles, which is not preferable. Therefore, it is necessary to use the aluminum alloy having the above hardness as the outer foil and the inner foil.
作用 この発明の両面艶消しアルミニウム合金箔の製造方法
により造つた中間箔のアルミニウム箔は両面が艶消しで
あり、両面とも平らであるので両面に印刷を普通に行え

われるので簡単でかつ低コストで両面艶消しを行える。Function The aluminum foil of the intermediate foil produced by the method for producing a double-sided matte aluminum alloy foil of the present invention has both matte sides and both sides are flat, so that printing can be normally performed on both sides. Furthermore, since both surfaces of the intermediate foil are matted at the same time when rolling is performed, both surfaces can be matted easily and at low cost.

塗布する。Example Between two outer foils made of an aluminum alloy foil having a hardness of about 70 HV and a thickness of 28 μm, the hardness of the outer foil is about 15
HV Small, about 55HV, 28μm thick aluminum alloy foil intermediate foil is interposed so that the rolling oil is present at a rate of 0.2g / m 2 between each aluminum alloy foil. Apply rolling oil to the surface of the aluminum alloy foil.
圧延油を塗布介在させた３枚重ねのアルミニウム箔を
圧延して圧下率が47％、即ち中間箔の厚さが20μｍで外
側箔の厚さが14.8μｍに圧延する。Three layers of aluminum foil coated with rolling oil are rolled and rolled to a rolling reduction of 47%, that is, the thickness of the intermediate foil is 20 μm and the thickness of the outer foil is 14.8 μm.

なる。The foils rolled in three layers are separated from each other by a separator and wound up, whereby the intermediate foil becomes a double-sided matte aluminum alloy foil. The outer foil is an aluminum alloy foil, one side of which is matte and the other side of which is glossy like the conventional product.

Since the soft intermediate foil is rolled while being protected by the harder outer foil, the intermediate foil can be matt on both sides while rolling, and it is flat with no pinholes or scratches. In addition, it is possible to produce a foil such as a double-sided matte aluminum alloy which is good in printing, relatively inexpensive, and good.
