An elastic tape with poor recovery may cause shoulder seams to loosen and necklines to sag after just a few uses, diminishing the garment's overall quality. So, what exactly affects the elastic recovery rate of TPU tape?

As a polymer material, TPU’s molecular structure becomes more active at elevated temperatures. If the temperature exceeds its tolerance range, the material may soften, deform, or even suffer permanent damage. Therefore, heat resistance is one of the key indicators for evaluating the quality of TPU elastic tape, directly affecting the shape stability and service life of finished garments.

In garment production, selecting the appropriate TPU elastic tape is not a one‑size‑fits‑all decision. It requires precise matching based on specific applications and performance requirements.

Sourcing TPU elastic tape from China may appear straightforward, but hidden pitfalls await the unwary. Many buyers, due to limited experience or information asymmetry, repeatedly make errors in product selection, testing, and supplier evaluation. The following four mistakes are the most common and most costly.
