What are the principles of the three protections of thermal paper?

The three anti principles of thermal paper involve three aspects: waterproofing, oil resistance, and anti friction (or anti alcohol, anti scratch). The specific explanation is as follows:

1、 Waterproof principle

Three proof thermal paper can be used normally in humid environments and is not easily damaged or deformed due to moisture. This is mainly because the three proof thermosensitive paper has a protective layer coated on the thermosensitive coloring layer, which can effectively block the penetration of moisture and protect the thermosensitive coating from moisture. This waterproof performance enables the three proof thermal paper to maintain clear and readable information even in humid or rainy environments.

2、 Oil proof principle

Three proof thermal paper has oil proof function, which means it is not easily contaminated by oil stains. In industries such as food processing and catering that are prone to contact with fats and oils, this oil resistance performance is particularly important. The oil proof principle also benefits from the protective layer on the surface, which can block the penetration and adhesion of grease, ensuring that the information printed on thermal paper is not contaminated by grease.

3、 Principle of anti friction (or anti alcohol, anti scratch)

Three proof thermal paper also has anti friction properties, which means it can prevent objects from rubbing against each other to a certain extent, maintaining the clarity and durability of printed content. In addition, some high-level three proof thermal paper also has the property of preventing organic solvents such as alcohol. This is mainly because the protective layer can not only improve the wear resistance of the paper, but also resist the erosion of organic solvents. By enhancing the hardness and wear resistance of the paper surface, three proof thermal paper can maintain the clarity and integrity of printed content during logistics transportation and use.

In summary, the three proof principle of thermal paper mainly benefits from its surface protective layer, which can effectively block the penetration and adhesion of moisture, oil, and organic solvents, while improving the wear resistance of the paper, thus maintaining good performance in various complex environments.
