TPU transparent elastic band tape in width of 25 mm is the wider one compared with that for clear bra straps. For this type of wide TPU tape, we will packed them in wheel to keep the flat and smooth shape.
Generally, TPU tape has elasticity because of the feature of TPU material. However, the wider and the thicker the tape is, the less elastic the clear tape is. Therefore, TPU transparent elastic band in spec. of HD25030T won't have much elasticity, but it still keep resilience. So we recommend customers use such a wide TPU band strap for invisible back bra strap. Besides clear tape in 25 mm wide, the tape in 20 mm and 30 mm wide are also suitable for clear back strap.
