What happens to the small roll of thermal label paper in a high temperature environment?

In a high temperature environment, the small roll of thermal label paper may undergo the following changes:

First, color change

The high temperature will cause the thermistin molecules in the printing layer of the thermal label paper to change, which may cause the text and images on the paper to become pale or even completely white. This is because the thermal color layer coated with thermal paper contains dark dye and color developer, when the temperature exceeds a certain threshold (usually thought to be above 70 ° C), the chemical balance between dark dye and color developer may be broken, resulting in the reversible appearance of the color reaction, so that the color that has been formed gradually fades.

Second, physical property changes

High temperature may also lead to changes in the physical properties of thermal label paper, such as paper deformation, curling and so on. This is because at high temperatures, the moisture and fibers in the paper may be affected, resulting in changes in the structure of the paper.

Third, print quality decline

When printing with thermal label paper in a high temperature environment, the print quality may decrease significantly due to the influence of the above color changes and changes in physical properties. Text and images can become blurred or even completely unrecognizable.

Fourth, shortened service life

Heat-sensitive label paper stored or used for a long time in a high temperature environment will greatly shorten its service life. This is because the high temperature accelerates the aging process of the chemicals in the paper, making the color reaction of the thermal paper more unstable, and the color is easier to fade.

Recommended countermeasures

In order to avoid the adverse effects of high temperature environment on thermal label paper, the following measures can be taken:

1.Storage environment: Store heat-sensitive label paper in a cool, dry, ventilated place, away from direct sunlight and high temperature environment. The recommended storage temperature ranges from 5 ° C to 35 ° C, and the relative humidity does not exceed 80%.

2.Use environment: When using heat-sensitive label paper, attention should also be paid to avoid the influence of high temperature environment. It is recommended to use an environment where the temperature ranges from 0 ° C to 50 ° C and the relative humidity does not exceed 80%.

3.Quality check: Check the quality and storage conditions of the thermal label paper before use. Do not use it if there are quality problems or improper storage conditions.

In summary, the high temperature environment has a significant negative impact on the small roll of thermal label paper, so special attention needs to be paid to avoid high temperature environments during storage and use.
