Thermal paper is not the same as the ordinary paper, as it is coated with some dye and chemicals. When you heat the thermal paper above its melting point, it reacts much due to the presence of dye and chemicals in it. A thermal paper may change its colour when the dye reacts to the chemicals. Thermal paper has three layers such as
- Substrate layer
- Active layer
The substrate layer consists of chemicals like polypropylene. Coming to the base layer, it consists of gelatin, alkali salts, and starches. This layer is important for allowing the heat to pass through the paper. Finally, the active layer is the top layer that contains the rich chemicals to react over the heat.
