How does the three proof thermal paper perform under prolonged exposure to light?

Under prolonged exposure to light, the performance of three proof thermal paper will be affected to some extent, but the specific degree of impact depends on multiple factors, including paper quality, coating material, light intensity, and duration.

Generally speaking, although three proof thermal paper has waterproof, oil resistant, scratch resistant and other characteristics, its sensitivity to light is still high. Long term exposure to light, especially strong direct sunlight, can cause the temperature on the surface of the paper to rise, thereby accelerating the decomposition and reaction of chemicals in the thermosensitive coating, causing the handwriting to gradually fade or blur.

In addition, if too much fluorescent powder or other chemical additives are added to the three proof thermal paper during the manufacturing process, it will also increase its sensitivity to light, leading to a higher risk of fading under long-term light exposure.

However, it is worth noting that there may be significant differences in the anti light performance of three proof thermal paper of different brands and models. Some high-quality three proof thermal paper uses special coating materials and manufacturing processes, which can resist the influence of light to a certain extent and extend the storage time of handwriting.

Therefore, when using three proof thermal paper, it is recommended to pay attention to the following points:

Choose high-quality products: Try to use well-known brands and high-quality three proof thermal paper to ensure its anti light performance and overall quality.

Avoid prolonged direct sunlight: When used outdoors, try to place the three proof thermal paper in a location away from direct sunlight to reduce the impact of light on it.

Reasonable storage: When not in use, the three proof thermal paper should be stored in a cool, dry, and well ventilated environment, avoiding prolonged exposure to sunlight or high temperatures.

In summary, although the three proof thermal paper may be affected by prolonged exposure to light, measures such as selecting high-quality products, avoiding prolonged direct sunlight, and reasonable storage can extend the storage time of its handwriting and improve its overall performance.
