Thermal Transfer Adhesive Labels

Thermal transfer adhesive labels are a type of label material based on thermal color development technology. Through the local heating of the thermal transfer head, the coating undergoes a chemical reaction, enabling the rapid generation of text, barcodes or patterns without the need for ink or carbon paper. The core structure consists of three layers: the bottom layer is a paper-based or synthetic material substrate, the middle layer is a thermal transfer coating containing color-developing agents and colorless dyes, and the top layer is a protective layer (some products may omit this layer).

**Main Features**:
1. **Environmental Friendliness**: Made of biodegradable materials, it reduces pollution caused by traditional inks. Some products are capable of natural decomposition;
2. **Efficiency and Economy**: Fast printing speed, low cost, suitable for large-scale production, and simple maintenance (no need to replace carbon ribbons);
3. **Diverse Applications**: Applicable to logistics labels, retail price tags, medical labels, food traceability and other scenarios. Widely used in electronic scales, cash registers and other devices;
4. **Storage Performance**: Depending on the coating formula, the storage time ranges from several months to 10 years. The regular type is suitable for short-term identification, while the long-lasting type can meet the needs of archive management and other requirements.

**Limitations**: Direct thermal-printed labels are prone to fading due to exposure to light and high temperatures. In contrast, heat transfer printing technology can enhance durability. Currently, this technology is being integrated with smart labels (such as RFID) to expand its innovative applications in the Internet of Things and supply chain management.
