What is the surface smoothness of colored thermosensitive synthetic paper?

The surface smoothness of colored thermosensitive synthetic paper is usually high. This is mainly due to its high-quality substrate and fine coating process.

Color thermal sensitive synthetic paper generally uses BOPP (biaxially oriented polypropylene) film as the substrate, which itself has the characteristics of flatness and smoothness. After undergoing biaxial stretching process, the molecular chain arrangement of BOPP film is more orderly, thereby improving the physical properties and surface glossiness of the material.

In addition, colored thermosensitive synthetic paper undergoes coating treatment during the manufacturing process. Coating materials typically contain heat sensitive chemicals that exist in the form of microcapsules or dyes within the coating. When the thermal print head applies heat to the paper, the thermal agent quickly undergoes a chemical reaction, causing a color change and forming a colored image or text on the paper. This coating process not only improves the printing effect of the paper, but also further enhances its surface smoothness.

However, it should be noted that there may be differences in surface smoothness between different brands and models of colored thermal sensitive synthetic paper. This is mainly influenced by factors such as production process, raw material quality, coating formula, etc. Therefore, when selecting color thermal sensitive synthetic paper, it is recommended to choose according to specific needs and applications to ensure the best printing effect and visual experience.

In summary, the surface smoothness of colored thermosensitive synthetic paper is usually high, thanks to its high-quality substrate and fine coating process. But the specific smoothness still needs to be evaluated based on the brand and model of the paper.
