［産業上の利用分野］
本発明は、水濡れ性のすぐれた容器などの包装
用アルミニウム箔に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an aluminum foil for packaging containers and the like with excellent water wettability.
［従来の技術］
従来、容器などの包装用に用いられるアルミニ
ウム箔は厚さが55〜200μで、多くは100μ前後で

に巻取り、表面に付着している圧延油を蒸発除去
するための焼鈍工程に付されるのが通常である。[Prior Art] Conventionally, aluminum foil used for packaging containers and the like has a thickness of 55 to 200 μm, and most have a thickness of around 100 μm. Usually, the steel is subjected to an annealing process to evaporate and remove rolling oil adhering to the steel.
ところが、コイル内部の圧延油は焼鈍工程にお

となる。また、エツチング、陽極酸化処理、化学
処理など水をベースとする処理剤で箔の表面を処
理する場合には、表面に残存する圧延油が邪魔に
なつて、均一な表面処理ができない。 However, the rolling oil inside the coil is not sufficiently evaporated and removed during the annealing process, and the rolling oil remains in the widthwise center of the foil, resulting in a portion with poor water wettability. Therefore, when such foils are used for packaging and are coated with organic substances such as ink or paint, or laminated, this may cause a decrease in adhesion. Furthermore, when the surface of the foil is treated with a water-based treatment agent such as etching, anodizing, or chemical treatment, the rolling oil remaining on the surface gets in the way, making it impossible to achieve a uniform surface treatment.
［発明が解決しようとする課題］
以上の欠点を除くため、溶剤脱脂、アルカリ性

上の問題があつて好ましくない。[Problems to be Solved by the Invention] In order to eliminate the above-mentioned drawbacks, removal of rolling oil using solvent degreasing, alkaline or weakly alkaline degreasing agents, etc., can be considered, but this is not preferred since it poses pollution problems such as air pollution and waste liquid treatment. do not have.
［課題を解決するための手段］
本発明はこの点を改善すべくなされたもので、

すぐれた包装用アルミニウム箔を要旨とする。[Means for solving the problem] The present invention has been made to improve this point,
Thickness 55~200μ manufactured by single lap rolling process
The present invention relates to an aluminum foil for packaging with excellent water wettability, characterized in that one or both surfaces of the overlapping surfaces of the aluminum foil have a surface roughness of 1.5 to 3μ in the rolling direction. do.
なお、本発明において面粗さというのは、JIS
B0601で規定されている表面粗さの最大高さ
（Rnax）を示すものである。 In addition, in the present invention, surface roughness is defined as JIS
This indicates the maximum height of surface roughness (R nax ) specified in B0601.
すなわち、第１図に示すように、本発明のアル
ミニウム箔１は矢印で示す圧延方向のＡ−Ａ拡大
断面が第２図に示すように表面に微細な凹凸２が
形成されているので、コイル状に巻取つたとき、
その凹凸２によつて箔１の重なり部分に空間が形

つて、箔をコイル状にして焼鈍した場合、蒸発し
た圧延油の蒸気が、この空間を通つて箔１の幅方
向に自由に拡散できるので、アルミニウム箔の表
面全体からの圧延油の蒸発が容易となる。 That is, as shown in FIG. 1, the aluminum foil 1 of the present invention has fine irregularities 2 formed on the surface as shown in FIG. When it is wound into a shape,
The unevenness 2 forms a space in the overlapping portion of the foil 1. This space has a shape in which the unevenness 2 is continuous in the width direction of the foil 1 because the rolling direction is the same. Therefore, when the foil is coiled and annealed, the steam of the evaporated rolling oil passes through this space. Since the rolling oil can be freely diffused in the width direction of the aluminum foil 1, the rolling oil can easily evaporate from the entire surface of the aluminum foil.
本発明においてアルミニウム箔の厚さを55〜
200μと限定してのは、55μ未満では強度が不足
し、容器の保形性が充分でなく、又200μを超え
ると重ね圧延では圧下率を大きくできないため所
定の面粗さが得られないためである。 In the present invention, the thickness of aluminum foil is 55~
The reason why it is limited to 200μ is that if it is less than 55μ, the strength will be insufficient and the shape retention of the container will not be sufficient, and if it exceeds 200μ, the reduction ratio cannot be increased in lap rolling and the specified surface roughness cannot be obtained. It is.
面粗さが1.5μより小さいと箔の幅方向に形成さ

着している圧延油の蒸気の拡散が充分でなく、水
濡れ性の不充分な部分が残る。一方、3μを超え
ても効果は変らず、面粗さを増すため圧下率を大
きくすると箔表面と圧延機の作業ロール表面との
間が潤滑不足となつて表面欠陥を生じる。 If the surface roughness is less than 1.5μ, there will not be enough space formed in the width direction of the foil, so the vapor of rolling oil adhering to the foil surface during annealing will not diffuse sufficiently, resulting in insufficient water wettability. Some parts remain. On the other hand, even if it exceeds 3μ, the effect remains the same, and if the reduction rate is increased to increase the surface roughness, there will be insufficient lubrication between the foil surface and the work roll surface of the rolling mill, resulting in surface defects.
粗面とするのは片面でも勿論よいが両面にする
とより効果的である。又、箔の幅方向も同様の粗
面とすることは何等差支えない。 Of course, it is possible to roughen one side, but it is more effective to roughen both sides. Further, there is no problem in providing a similar rough surface in the width direction of the foil.
かかるアルミニウム箔を容易に製造するには、
アルミニウム箔素材を２層以上重ねて、各層の厚
さが55〜200μで少なくとも片面の面粗さが圧延

工するとよい。 To easily manufacture such aluminum foil,
It is preferable to stack two or more layers of aluminum foil material and cold-work the aluminum foil material by 25% or more so that the thickness of each layer is 55 to 200μ and the surface roughness of at least one side is 1.5 to 3μ in the rolling direction.
これを図面に基づいて説明すると、第３図は一

５を巻取りロール６，６に分離しながら巻取つて
ロール状に形成し、焼鈍工程を付す。 To explain this based on the drawings, Fig. 3 is an explanatory diagram of an example, in which two layers of aluminum foil materials 5, 5 are stacked and passed between the work rolls 3, and the thickness of the foil is 55 to 55 mm.
Cold-rolled by 25% or more to achieve a thickness of 200μ. 4 is Backup Prowl. After rolling, unevenness 2 is formed on the overlapping surfaces of the rolled aluminum foils 1, 1. This unevenness 2 is in the rolling direction.
It becomes 1.5 to 3μ. Such rolled aluminum foil 5,
5 is separated into winding rolls 6, 6, wound up to form a roll shape, and subjected to an annealing process.
上記はアルミニウム箔１を２枚重ねて冷間圧延
するものであるが、３枚以上重ねて同時に冷間圧
延をすると中間のアルミニウム箔は両面に凹凸が
形成され、これを巻取ると、圧延油の蒸発効果が
一層向上する。 In the above example, two sheets of aluminum foil 1 are piled up and cold rolled, but when three or more sheets are piled up and cold rolled at the same time, unevenness is formed on both sides of the middle aluminum foil, and when it is wound up, rolling oil evaporation effect is further improved.
つぎに具体的な実施例について述べる。 Next, specific examples will be described.
