What is thermal label paper?

Thermal label paper is a kind of paper treated with a high thermal sensitive coating. The high sensitivity of this paper makes it suitable for low-voltage printheads, which greatly reduces wear on the printheads. Here is a detailed explanation of the thermal label paper:

Structure: Thermal label paper is usually divided into three layers, including paper base, thermal coating and protective layer. Among them, the thermal coating and protective layer are important factors affecting the quality of the label paper. If the thermal coating is not uniform, there may be different shades of color when printing, resulting in a decline in print quality. At the same time, the protective coating can absorb some of the light that causes the chemical reaction of the hot coating to slow down the deterioration of the printing paper and protect the printer components.

Characteristics and testing: The thermal label paper has the characteristics of non-waterproof, non-oil-proof and tearable. A simple test is to run a fingernail across a piece of paper so hard that it leaves a black scratch.

Application: Thermal label paper is widely used in supermarket electronic scale labels, chemical laboratories and need to print commodity labels, price labels, bar codes occasions. They can be easily attached to the outer packaging of goods or used as shelf labels. In addition, thermal paper is also suitable for cold storage, freezers and other environments, and its size is mostly fixed in the 40mmX60mm standard. However, different sizes and specifications can also be provided according to demand.

Post-press processing and storage: Thermal label paper is suitable for letterpress, offset and flexographic printing. Under specific environmental conditions, such as 24 ° C and 50% relative humidity, thermal label paper can be stored for one year. For post-press processing, different types of backing paper can be used, such as yellow coated plastic backing paper, Glasin backing paper and yellow colored cow backing paper, respectively, for different printing and processing needs.

Note of use: When using thermal label paper, it is very important to keep the printer clean and maintained to ensure print quality and clarity. At the same time, choosing the right paper and glue is also a key factor to ensure that the label is firmly pasted and lasting.

In general, thermal label paper plays an important role in commercial, retail and laboratory fields because of its convenient and fast printing characteristics and a wide range of application scenarios.
