The Applications and Features of Thermal Paper

1. Working Principle of Thermal Paper
Thermal paper is coated with a chemical layer containing a dye and a color developer. When exposed to the heat generated by the thermal printer head, the dye reacts chemically with the developer to produce images or text. This unique mechanism eliminates the need for ink or ribbons, simplifying the design and maintenance of the printing equipment.

2. Key Features of Thermal Paper
Efficiency and Convenience
Thermal printing is simple to operate and offers high-speed performance, making it ideal for high-frequency printing tasks. The lack of ink or ribbon replacements saves both time and costs.

Low Noise
Thermal printers operate with minimal mechanical noise, making them suitable for quiet environments such as hospitals and offices.

Eco-Friendly and Cost-Effective
Thermal paper production and usage consume fewer resources, and its straightforward printing supplies contribute to environmental friendliness. Additionally, its low cost makes it a preferred choice in many industries.

Versatility
Thermal paper is suitable for various printing needs, such as receipts, labels, and tickets, and can perform well under different temperature and humidity conditions.

3. Applications of Thermal Paper
Retail Industry
Thermal paper is extensively used in cash register systems for printing shopping receipts. Its fast and low-cost characteristics make it a standard consumable in supermarkets and convenience stores.

Logistics Industry
Thermal paper plays a vital role in printing shipping labels and logistics tags. Its clear barcode printing ensures precise information transmission, greatly enhancing logistics efficiency.

Healthcare Industry
Hospitals often use thermal paper for printing medical barcodes, test reports, and medical records. The paper’s speed, clarity, and ease of preservation meet the high demands of healthcare scenarios.

Financial Industry
Thermal paper is also widely used for ATM receipts and POS transaction slips, helping financial institutions streamline their processes.

4. Storage and Precautions
Although widely used, thermal paper’s chemical coating is sensitive to light, heat, and humidity. Prolonged exposure to such environments can cause printed content to fade. Therefore, thermal paper should be stored in a dry, dark place and kept away from oil-based substances.
