In addition, the width of the paper sheet included in the first segment 510 may be about 120 mm, respectively, and the width of the paper sheet included in the second segment 520 may be about 100 mm, respectively, and the paper sheet including the first segment 510 may have a width of about 100 mm, respectively. Each sheet may have a width of about 120 mm, and each of the paper sheets included in the second segment 520 may have a width of about 110 mm, but is not limited thereto.

In an embodiment, the paper sheet impregnated with the first liquid composition and the paper sheet impregnated with the second liquid composition may have different thicknesses. For example, each of the paper sheets included in the first segment 510 may have a thickness of about 200 μm, and each of the paper sheets included in the second segment 520 may have a thickness of about 210 μm. In addition, each of the paper sheets included in the first segment 510 may have a width of about 210 μm, and each of the paper sheets included in the second segment 520 may have a width of about 230 μm, but is not limited thereto.

In an embodiment, the paper sheet impregnated with the first liquid composition and the paper sheet impregnated with the second liquid composition may have different weights.
