Does BOPP color thermosensitive synthetic paper fade at high temperatures?

BOPP color thermosensitive synthetic paper does have the possibility of fading in high temperature environment. This is mainly due to the special properties of heat-sensitive synthetic paper and the combined effect of external environmental factors. Here's a closer look at the problem:

First, the characteristics of thermal synthetic paper

Thermal synthetic paper is a kind of processing paper, the manufacturing principle is to coat the base paper with a layer of "thermal paint" (thermal color change layer). This heat-sensitive coating contains a leach dye and a color developer, and when heated, the leach dye reacts chemically with the color developer to change the color and achieve the purpose of printing or displaying information. However, this chemical reaction is sensitive to temperature, and high temperatures may accelerate the reaction process, resulting in color changes or fading.

Second, the impact of high temperature environment

1.Temperature: High temperature is one of the important factors leading to the fading of thermal sensitive synthetic paper. When the ambient temperature is too high, the chemicals in the heat-sensitive coating may accelerate the reaction, making the color become unstable and even fade.

2.Humidity: In addition to temperature, humidity may also have an impact on the color stability of thermal synthetic paper. In high temperature and humidity environments, paper is prone to moisture, which may accelerate the color change process.

3.Light: especially ultraviolet light, also has a significant effect on the color stability of heat-sensitive synthetic paper. After prolonged exposure to sunlight or strong light, the image on the paper may gradually fade.

Third, suggestions to avoid fading

1.Storage environment: Try to avoid exposing BOPP color thermosensitive synthetic paper to high temperature, high humidity or direct sunlight for a long time. It is best stored in a cool, dry place away from light.

2.Conditions of use: During use, attention should also be paid to avoid direct exposure to high temperature and strong light. Especially in the printing or display process, the temperature and humidity of the surrounding environment should be controlled.

3.Material selection: When designing and selecting thermal synthetic paper, you can consider using materials that are less sensitive to ultraviolet light and light to improve their color stability.

Fourth, conclusion

In summary, BOPP color thermal synthetic paper is indeed likely to fade in a high temperature environment. In order to avoid this situation, appropriate storage and use measures need to be taken to ensure the color stability and service life of the paper. At the same time, the selection of materials should also fully consider its temperature resistance, light resistance and other performance characteristics.
