What is the technology of transparent thermal label paper

Transparent thermal label paper is a label material made with a specific technology, and its core technology involves the following aspects:

Material selection:

Transparent substrate: Transparent thermal label paper usually uses transparent materials such as polyester film and polypropylene film as the substrate, of which polyester film is most commonly used for its excellent performance.

Thermal coatings: thermal coatings are composed of thermal agents, resins, fillers, solvents and other raw materials, which mainly play the role of color rendering, curing, light resistance, heat resistance, wear resistance and so on.

Production process:

Coating process: The thermal sensitive coating is evenly coated on the transparent substrate through the rolling coating equipment, and the coating quality, coating speed and coating thickness should be controlled during the process to ensure the final thermal paper quality.

Drying treatment: After coating, the transparent thermal paper needs to be dried, and the temperature, humidity and drying time in the oven are controlled through the roller oven or other drying equipment to ensure that the thermal coating is fully cured.

How it works:

The working principle of thermal paper is based on thermal chemical formulations. When the thermal paper is heated, the colorless dye and the color developer react in a certain temperature environment, resulting in color changes and the formation of graphics. The process is fast, clean and efficient.

Application field:

Transparent thermal label paper is widely used in a variety of occasions that require fast and efficient label printing, such as transportation labels in logistics and transportation, bar codes and product labels.

Performance characteristics:

Transparency: The transparent substrate enables the thermal label paper to clearly display graphic information after printing, and does not affect the visual effect of the item to be affixed.

High efficiency: Thermal printing technology is fast and clean, and can meet a large number of fast label printing needs.

Durability: By optimizing the coating formulation and coating process, transparent thermal label paper has good water, oil and friction resistance, and can maintain a long service life in a variety of environments.

In summary, transparent thermal label paper is a label material made with a specific technology, and its core technology involves material selection, production process, working principle and performance characteristics. The application of these technologies makes transparent thermal label paper an indispensable and important material in logistics, transportation and other industries.
