What determines the scratch resistance of three proof thermal paper?

The scratch resistance of three proof thermal paper mainly depends on the following factors:

1. Quality and formula of thermal sensitive coating

Uniformity: The uniformity of thermal sensitive coatings is crucial for their scratch resistance performance. Uneven coating may lead to a decrease in printing quality and also affect the scratch resistance effect.

Chemical formula: The chemical formula of the thermosensitive coating determines its scratch resistance. High quality formulas can provide stronger wear resistance and scratch resistance.

2. Material and process of protective layer

Material selection: Three proof thermal paper usually has a protective layer applied on top of the thermal coloring layer, and the material of this protective layer has a significant impact on its scratch resistance performance. Choosing materials with high wear resistance can significantly improve scratch resistance.

Coating process: The coating process of the protective layer can also affect the scratch resistance performance. A good coating process can ensure a tight bond between the protective layer and the thermosensitive coloring layer, thereby improving the overall scratch resistance.

3. Paper structure and strength

Paper strength: The strength of the paper itself can also affect its scratch resistance. Paper with higher strength can better resist external scratches and wear.

Interlayer adhesion: The adhesion between the layers of paper is also one of the factors that affect the scratch resistance performance. Paper with strong adhesion is less prone to delamination or damage when scratched.

4. Use environment and conditions

Environmental factors: Factors such as humidity and temperature in the usage environment may also affect the scratch resistance of the three proof thermal paper. In extreme environments, the performance of paper may change, thereby affecting its scratch resistance.

Usage: The way paper is used can also affect its scratch resistance performance. For example, frequent bending, folding, or rubbing of paper can accelerate its wear and aging.

In summary, the scratch resistance of three proof thermal paper depends on the combined effect of multiple factors. To improve the scratch resistance performance, efforts can be made to optimize the thermal sensitive coating formula, select high-quality protective layer materials and processes, enhance paper strength, and improve the usage environment and conditions.
