How does the long-lasting three proof thermal paper perform at different environmental temperatures?

The performance of long-lasting three proof thermal paper varies at different environmental temperatures. The following is a specific analysis of its performance:

1、 Performance under normal ambient temperature

Under normal environmental temperature (such as 20-25 ℃) and humidity conditions, long-lasting three proof thermal paper can exhibit good printing effects and storage performance. Its thermal sensitive coating can react normally, and the printed text or images are clear, vivid, and have good durability. Meanwhile, due to its waterproof, oil resistant, and alcohol resistant properties, the shelf life of long-lasting three proof thermal paper is relatively long in these conventional environments.

2、 Performance in high temperature environment

When the ambient temperature exceeds the tolerance range of the long-lasting three proof thermal paper (such as above 70 ℃), its thermal sensitive coating may change color or deteriorate, thereby affecting the printing effect and shelf life. In high temperature environments, the thermal reaction of thermal paper may become unstable, resulting in blurry and unclear printed text or images. In addition, high temperatures may accelerate the aging process of thermal sensitive coatings and shorten their service life.

3、 Performance in low temperature environment

Compared with high-temperature environments, long-lasting three proof thermal paper performs relatively well in low-temperature environments. Generally speaking, within the temperature range of -20~70 ℃ (depending on product characteristics), long-lasting three proof thermal paper can still maintain good printing effects and storage performance. However, under extreme low temperature conditions (such as near -20 ℃), although the thermal sensitive coating itself will not deteriorate due to low temperature, the heating effect of the print head may be affected, resulting in poor printing performance.

4、 Performance in humid environments

The humid environment has a certain impact on the storage performance of long-lasting three proof thermal paper. Although long-lasting three proof thermal paper has waterproof properties, its thermal coating may become damp and deteriorate when exposed to high humidity environments for a long time, thereby affecting the printing effect and shelf life. A humid environment may also cause mold spots or spots on the surface of thermal paper, further reducing its printing quality and aesthetics.

In summary, the performance of long-lasting three proof thermal paper varies at different environmental temperatures. In order to maintain its good printing effect and storage performance, it is recommended to pay attention to controlling the environmental temperature and humidity during use and storage, and avoid prolonged exposure to extreme environmental conditions. At the same time, when choosing long-lasting three proof thermal paper, attention should also be paid to its product characteristics and scope of use to ensure that it can meet practical application needs.
