Why add a protective layer on the three proof thermal paper?

There are several main reasons for adding a protective layer to three proof thermal paper:

1、 Enhance protective performance

Waterproof performance:

The protective layer can effectively block the penetration of moisture, keeping the paper dry in humid environments, thereby ensuring the clarity and readability of printed content.

Oil resistance performance:

The protective layer can prevent oil stains from contaminating the paper and keep it clean, which is particularly important for labels that need to be used in greasy environments.

Scratch resistance performance:

The protective layer can enhance the scratch resistance of the paper, making it less susceptible to damage when subjected to external forces, thereby extending the service life of the label.

2、 Improve durability

Protect the color layer:

The protective layer can protect the color development layer of thermal paper from external factors such as light, humidity, etc., thereby ensuring the durability of printed content.

Extend service life:

Due to the presence of the protective layer, the service life of the three proof thermal paper is extended, the frequency of paper replacement is reduced, and the cost of use is lowered.

3、 Adapt to diverse application scenarios

Application in professional fields:

Three proof thermal paper is commonly used in professional fields, such as advanced thermal recording paper for precision experiments such as electrocardiograms and fetal monitors in hospitals. These scenarios require high waterproof, oil resistant, and scratch resistant performance of the paper.

Adaptability to harsh environments:

In industries such as logistics, food packaging, and retail, labels need to withstand various harsh environments such as humidity, greasiness, and friction. The presence of a protective layer enables the three proof thermal paper to better adapt to these environments.

4、 Protect the print head

Reduce friction:

The protective layer can reduce the friction between the print head and the paper, thereby reducing the wear of the print head and extending its service life.

Preventing pollution:

The protective layer can also prevent ink, dust and other pollutants on the paper from adhering to the print head, maintaining the cleanliness of the print head and stable printing effect.

In summary, adding a protective layer to the three proof thermal paper can significantly improve its protective performance, durability, and meet the needs of diverse application scenarios. At the same time, the protective layer can also protect the print head and extend its service life. Therefore, the protective layer is an indispensable and important component of the three proof thermal paper.
