What is the surface flatness of the three proof thermal paper?

The surface flatness of three proof thermal paper is usually high. The following is a detailed analysis of the surface flatness of the three proof thermal paper:

1、 Material characteristics

The three proof thermal paper adopts a special surface material, which has the functions of waterproofing, oil resistance, and chemical corrosion resistance (such as PVB resistance). The selection and design of this special surface material helps to improve the surface smoothness of the paper. At the same time, three proof thermal paper usually uses hot melt adhesive, which has good initial viscosity and can adapt to some uneven labeling surfaces, thus ensuring the flatness of the labeled surface to a certain extent.

2、 Production process

In the production process, three proof thermal paper needs to go through multiple steps such as calendering and coating. These steps have a direct impact on the surface smoothness of the paper. Advanced production processes can better control the microstructure of the paper surface, thereby achieving higher flatness. In addition, the machine die-cutting adopts modern equipment, which makes the cutting edge of the three proof thermal paper neat, without lifting or curling, further ensuring the flatness of the paper.

3、 Surface characteristics

The surface material of the three proof thermal paper has high smoothness and good glossiness. This smoothness makes the paper surface flat and easy to print. Meanwhile, the smoothness of paper directly affects the clarity and durability of printing. Paper with high smoothness can better absorb and disperse the heat of the print head, making ink dots more evenly distributed on the surface of the paper, thereby improving the clarity of printing.

4、 Practical application

In practical applications, three proof thermal paper performs well due to its high surface flatness. For example, in situations where high-definition printing is required (such as medical diagnostic reports, supermarket price labels, etc.), three proof thermal paper can ensure that the printed content is clear and visible. In addition, its flat surface also helps prevent problems such as paper jams or damage to the print head during the printing process.

In summary, the surface flatness of three proof thermal paper is usually high, thanks to its special material selection, advanced production technology, and good surface characteristics. In practical applications, three proof thermal paper can perform well and meet various high-definition printing and labeling needs.
