What is the color realization method of BOPP color thermal synthetic paper?

The color realization method of BOPP color thermal synthetic paper mainly involves the application of thermal technology and color materials. Here is a detailed explanation of how it is implemented in color:

1. Basis of heat-sensitive technology

BOPP color thermal synthetic paper uses the principle of thermal sensitivity to achieve color change. The surface of the thermal paper is coated with a special thermal coating that contains chemicals such as dark dyes and acidic substances. These chemicals remain colorless at room temperature, but when stimulated by a certain temperature, chemical reactions occur, resulting in color.

2. The role of leuco dyes

Dark dye is the key to realize color in thermal synthetic paper. The dye itself is colorless, but when heated reacts with other chemicals in the coating, such as acids, to form colored compounds that show color on the paper. The type and formulation of the leach dye determines the final color type and effect.

3. The cooperation of thermal printer

The color realization of BOPP color thermal synthetic paper is inseparable from the cooperation of thermal printer. Thermal printers heat specific areas of paper through their heating print heads. When the heated print head is in contact with the heat-sensitive synthetic paper, the high temperature generated by the print head causes the dark dye and acid on the surface of the paper to melt into a liquid and undergo a chemical reaction, thus appearing on the paper the desired text or image.

4. Color design and control

In order to achieve specific color effects, BOPP color thermal synthetic paper needs to be precisely designed and controlled during the production process. This includes selecting the appropriate formulation of dark dyes and acids, adjusting the thickness and uniformity of the thermal coating, and controlling the heating temperature and printing speed of the thermal printer. Through these measures, it is possible to ensure that the thermal sensitive synthetic paper can stably display the desired color and pattern after heating.

5. Environmental protection and durability considerations

In the process of color realization of BOPP color thermal synthetic paper, factors such as environmental protection and durability need to be considered. For example, you can choose environmentally friendly dark dyes and additives to reduce environmental pollution; At the same time, by optimizing the formula and process of the thermal sensitive coating, the properties of light resistance, heat resistance and moisture resistance of the thermal sensitive synthetic paper can be improved, and its service life can be extended.

In summary, the color realization method of BOPP color thermal synthetic paper is based on the principle of thermal technology and the application of dark dyes. Through the cooperation with the thermal printer and the precise color design and control, a rich variety of color patterns and text can be displayed on the paper. At the same time, factors such as environmental protection and durability need to be considered to ensure product quality and performance.
