First, what is the material of thermal paper?
Thermal paper is a special kind of paper, its main materials include thermal sensitive coating, substrate and protective coating. Among them, the heat sensitive coating is the most critical part of the thermal paper, which can sense the temperature change of the outside world, resulting in chemical reactions to form text, patterns, etc. The substrate is responsible for supporting the heat sensitive coating, and the commonly used substrate is paper, polyester film, etc. The protective coating is a film used to protect the surface of the heat-sensitive paper.
Second, what are the uses of thermal paper?
