First, verify the material composition – genuine TPU (thermoplastic polyurethane) should be free from recycled content, plasticizers, and latex. Request the supplier’s technical data sheet and, if possible, a small sample for physical testing. Second, examine the tape’s surface and edges.

Three of the most common problems are slipping, breaking, and uneven stitching. Slipping occurs when the elastic tape shifts during sewing, causing it to emerge from the seam misaligned or to create puckers in the fabric.

Clear elastic tape is prized for its ability to disappear into light‑colored fabrics, but when it turns yellow, that advantage vanishes. Understanding the causes of yellowing helps manufacturers and consumers choose better materials and care for garments properly.

For garment manufacturers and consumers alike, the ability of an elastic tape to withstand frequent laundering is a critical measure of quality. TPU elastic tape, made from thermoplastic polyurethane, has gained a reputation for excellent washing test performance.
