What is the heat resistance of heat-sensitive label paper?

The heat resistance of heat-sensitive label paper varies by type and quality. The following is a detailed analysis of the heat resistance of heat-sensitive label paper:

Heat resistance temperature range:

General thermal paper, its heat resistance temperature is usually between 50 ° C and 80 ° C. Specifically, the heat resistance temperature of phenolic thermal paper is higher, which can reach about 80 ° C, while the heat resistance temperature of acrylic thermal paper is generally about 50 ° C.

For some special types of thermal labels, such as removable thermal labels, the temperature range is wider, from -50 ° C to +90 ° C. This means that this type of label paper can maintain stable performance over a wide temperature range.

Performance in high temperature environment:

It should be noted that although thermal paper has a certain heat resistance, due to its weak material, it may still cause chemical reactions in the high temperature environment. This reaction may affect the printing effect, such as causing the print content to be blurred or the image to be unclear.

High quality thermal label paper can maintain good printing quality in high temperature environment and is not easy to fade or blur. Poor quality label paper may decline in printing quality under high temperature conditions.

Selection suggestions:

When you need to use heat-sensitive label paper in a high temperature environment, you should choose products with high heat resistance and good quality. You can check the product's quality certification and related test reports to evaluate its heat resistance.

In addition, considering the specific requirements of different application scenarios, for example, if the label is removable and does not retain glue, you can select the corresponding movable heat-sensitive label.

In summary, the heat resistance of thermal label paper depends on its type and quality. When selecting, its heat resistance should be evaluated according to the specific use environment and needs, and the appropriate product should be selected.
