What is the temperature resistance range of the three proof thermal paper?

The temperature resistance range of three proof thermal paper varies depending on the quality and application environment. Generally speaking, the temperature resistance range of ordinary three proof thermal paper is between -15 ℃ and+60 ℃. However, high-quality or specially designed three proof thermal paper may have a wider temperature resistance range. For example, the temperature resistance range of some high-quality three proof thermal paper can be extended to -50 ℃ to+90 ℃.

In addition, some special types of three proof thermal paper, such as removable thermal labels, also have a similar temperature resistance range, usually between -50 ℃ and+90 ℃. These labels will not leave any adhesive residue on the surface of the object when peeled off after being attached, making them particularly suitable for situations where frequent label replacement is required.

Another theory is that three proof thermal paper that meets specific standards (such as Fulfill ROHS, REACH) can be suitable for an ambient temperature range of -20 ℃ to+70 ℃ after 24 hours of labeling. However, it should be noted that this type of paper is usually not recommended to be exposed to environments above 50 ℃ or direct sunlight for a long time.

Overall, the temperature resistance range of three proof thermal paper is a relatively flexible parameter, which depends on the quality of the paper, manufacturing process, and application scenarios. When choosing three proof thermal paper, it is recommended to choose the appropriate temperature resistance range based on the specific usage environment and requirements to ensure that the label can maintain good performance and readability under various temperature conditions.
