HD3031T is in width of 3 mm, which is in a narrow width. Therefore, we usually recommend this size of clear elastic trims for customers if they need clear hanger loops. Of course, the narrow width clear TPU tape won't have good strength as wide tape do. So clear elastic trims in width of 3 mm and 4 mm will be recommended for clothes in thin weight. If customers need it for heavier clothes, clear elastic tape in 5 mm or 6 mm wide will be suitable.
Because of the narrow width, we generally pack 3 mm clear tape in roll rather than in wheel.
