Will the three proof thermal paper deform or shrink at high temperatures?

Three proof thermal paper may indeed deform or shrink at high temperatures, but the specific situation depends on the quality of the paper, the degree of temperature rise, and the duration.

Generally speaking, the surface of three proof thermal paper has a chemical coating, which requires high environmental temperature. It is usually recommended to control the temperature below 30 degrees. If the temperature is too high, the printed words may disappear, and the paper may also deform or shrink. Especially under long-term high temperature or extreme high temperature conditions, the stability of the three proof thermal paper may be affected, leading to changes in its physical form.

However, the heat resistance of three proof thermal paper of different brands and specifications may vary. Some high-quality three proof thermal paper adopts special production processes and materials, which may have better high-temperature resistance and can resist deformation or shrinkage caused by high temperature to a certain extent.

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

Try to avoid exposing the three proof thermal paper to high temperature environments, especially under prolonged or extreme high temperature conditions.

Choose reliable quality and high temperature resistant three proof thermal paper brands and products.

During storage and transportation, ensure that the three proof thermal paper is in a suitable temperature and humidity environment to extend its service life and maintain its stable performance.

In summary, although the three proof thermal paper may deform or shrink at high temperatures, choosing high-quality products and paying attention to the usage environment can to some extent reduce this risk.
