Thermal labels are coated with a colorless thermal coating on the surface of ordinary offset labels. Under the action of the heat of the print head, the heat-sensitive parts of the thermal label turn black. The parts that are not sensitive to heat do not change color, thus forming text or barcodes to achieve the purpose of printing. Thermal labels are divided into two types: with a protective layer and without a protective layer. The protective layer is above the thermal layer to protect the thermal layer, resist chemical corrosion, and prevent label contamination (such as sweat on hands, labels for blood banks) blood, etc.)and to protect the print head. The thermal coating can be designed with different activation temperatures as required to meet the needs of printers with different performances.
Direct thermal label has a chemical layer applied to a paper or synthetic base that is activated by heat. When the label is printed through a direct thermal printer, the small elements on the printer heat up and activate parts of the chemical layer to create the image required. They can be suitable for direct thermal label printers, weight scale printers, barcode printers, mobile printers, EPOS printers, and PDA terminals.
