The present invention relates to a membrane of a cargo hold, a cargo hold having the same, and a manufacturing method thereof. According to an embodiment of the present invention, the membrane is formed by multiple parallelogram-shaped pieces welded along multiple weld lines. Parts of the pieces are welded by first weld lines, which are extended in a direction, and second weld lines, which pass through the ends of the first weld lines and cross the first weld lines. At least one of the pieces is welded by the second weld lines and has a corrugation part extended in a direction crossing the extension line of the first weld lines. Therefore, the present invention improves workability when the pieces are welded and enables uniform welding. |
