What are the maximum and minimum temperatures that PET thermal sensitive silver paper can withstand?

The maximum and minimum temperatures that PET thermosensitive silver paper can withstand vary depending on the specific material formula and production process. The following is a summary scope based on existing information:

Maximum temperature tolerance

In general, the high temperature resistance of PET thermosensitive silver paper can reach 80-120 ℃, and even some special formulations or PET thermosensitive silver paper using special substrates (such as aluminum foil) can have a higher high temperature resistance, reaching 250 ℃ or even over 300 ℃. This high-performance PET thermosensitive silver paper has significant advantages in high-temperature application scenarios.

Minimum temperature tolerance

The low temperature resistance range of conventional PET labels is usually around -20 ℃, but some special formulations of PET thermosensitive silver paper can remain stable at lower temperatures, such as below -70 ℃. This enables PET thermosensitive silver paper to maintain good adhesion performance and printing clarity even in low-temperature environments.

Overall consideration

In practical applications, the temperature range that PET thermosensitive silver paper can withstand also needs to consider other factors, such as the labeling environment, the material of the bonding surface, and the length of use time. Therefore, when choosing PET thermosensitive silver paper, its temperature range should be determined based on specific application scenarios and requirements.

Precautions

Although PET thermosensitive silver paper has a high temperature tolerance range, its performance may still be affected under extreme temperature conditions (such as prolonged exposure to high or low temperatures), such as decreased adhesion and blurred printing. Therefore, care should be taken to avoid prolonged exposure to extreme temperatures during use.

In summary, the temperature range that PET thermosensitive silver paper can withstand varies depending on the specific material formula and production process. When selecting and using, the temperature range should be determined based on specific application scenarios and requirements, and attention should be paid to avoiding prolonged exposure to extreme temperatures to ensure stable performance.
