- a large triangular pattern 10 having one side thereof is continuously formed.
- the present invention is composed of the large triangular pattern 10 and the small triangular pattern 20 of the equilateral triangle shape is that the formation of the pattern, which is closely related to the air discharge, is linearity, the number of directions, the number of vertices and the passage capacity. Considering the shape of the pattern in terms of regular hexagon, square, and equilateral triangle, the air discharge efficiency has the best equilibrium triangular pattern.
- the air discharge pattern (W) is a protrusion formed by repeatedly forming a constant unit shape such as a square, hexagon, or triangle shape on the release paper (1) A pattern is formed, and the air discharge pattern W corresponding to the protruding pattern is formed on the adhesive layer 2 attached to the release paper 1.
- the area of the adhesive surface excluding the air discharge pattern of the rectangular unit shape of the conventional product is
- Interline Width (334.5 ⁇ m) * Interline Width (334.5 ⁇ m) 111,890 / ⁇ m 2

Because of its depth and shape, the air is smoothly discharged during construction, so that the air can be completely removed, so there is no appearance defect, and even if the base paper of the adhesive sheet is different in the longitudinal direction or horizontally, the air exhaust pattern is different. Since it remains as it is, the air discharge can be made smoothly, such that the difference in glossiness according to the elongation does not occur.
