How to avoid TPU tape becoming yellow?

TPU elastic tape play a crucial role in many garments. However, during extended storage and use, they can be affected by factors that may lead to a significant issue – yellowing. Though getting yellow is the shortage of all of plastic products, but we still have some tips to help you solve the problem.

1. Avoid light exposure

Light exposure is one of the primary factors causing yellowing in TPU tape. Therefore, it is wise to store them in a place away from direct sunlight. Both direct sunlight and prolonged exposure to ultraviolet (UV) rays can darken the color of TPU clear elastic tape. Choosing a cool storage environment or using opaque containers is an effective way to preserve the original color.

2. Prevent contact with air

Contact with air may lead to oxidation reactions in TPU elastic tape, resulting in yellowing. To avoid this, consider placing the tape in a sealed bag, minimizing their exposure to air. Using vacuum-sealed bags is a good choice, as they can effectively prevent oxygen and moisture from entering.

3. Stay away from humid environments, use cardboard boxes

Humid environments are not friendly to TPU tape. Moisture can cause water spots on the surface of the tape and accelerate the yellowing process. Choose to store TPU elastic tape in cardboard boxes, which can absorb some moisture, maintaining a relatively dry environment. Additionally, placing some desiccants, such as silica gel bags, in the box can further reduce the impact of humidity.

4. Avoid high-temperature environments

TPU elastic tape are susceptible to the effects of high temperatures. Excessive heat can lead to deformation and color changes in the material. Therefore, when storing TPU tape, opt for a relatively cool place, away from any devices or areas that may generate high temperatures.

5. Regular inspection and sun exposure

Regularly checking storage conditions and taking appropriate measures are crucial to maintaining the appearance of TPU elastic tape. In addition to avoiding direct sunlight, periodically placing TPU elastic tape in a well-ventilated area can help volatilize any volatile substances that may contribute to yellowing.

In conclusion, preventing the yellowing of TPU tape requires a series of meticulous measures aimed at minimizing contact with factors that cause discoloration. By choosing appropriate storage conditions, moisture-prevention measures, and light-avoidance methods, we can ensure that clear elastic tape remain clear and vibrant throughout their lifespan, providing enduring aesthetics and practical value to garments.
