Thermochromic labels utilize the temperature-sensitive properties of special inks to achieve different color changes on the label surface under specific temperature conditions. The temperature change can be either reversible or irreversible, and multi-stage color changes are also possible. Thermochromic labels are widely used in applications such as food and beverage packaging, medical product monitoring, and industrial process inspection.

Functions and Features of Thermochromic Labels:
1. Unique visual effects that enhance product competitiveness;
2. Customizable colors at room temperature, high temperature, and low temperature as required;
3. Supports transitions between different colors;
4. Compared to electronic monitoring devices, thermochromic labels are cost-effective and more suitable for large-scale applications;
5. No equipment needed; simple and easy to use—just observe the color change of the label.
