Wholesale Thermal Self Adhesive Label Sticker Barcode Label Manufacturer

Thermal labels. 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.

Now barcode labels are widely used, and jflabel barcode label stickers are also born accordingly. Printer-printed label barcodes are commonly used in all walks of life. Printing barcode labels can design the internal pattern of the label, and the barcode content is printed on the actual carrier on the label paper. The biggest difference between barcode labels and ordinary labels is the difference in material.

Barcode printers are also known as label printers. Barcode printers only support roll paper, and roll paper labels can be single-row, double-row or triple-row. The type of label paper used is limited by the printing format (print width) of the printer. The selected label stock size cannot exceed the maximum print width of the printer. Therefore, when purchasing a printer or label paper, be sure to pay attention to the printing width of the printer.

For printing barcode labels, you can choose different printing methods according to the material of the inserted label paper. There are two printing methods for printing barcode labels: one is thermal printing and the other is thermal transfer. The thermal printing method does not use carbon ribbon (carbon ribbon), but directly prints one-dimensional code, two-dimensional code, text, pattern, etc. on the label material. It has special label paper - thermal paper. Thermal paper is a processed paper, generally divided into three layers, from the bottom layer to the upper layer, namely: paper base, thermal coating, protective layer. When printing thermal barcode labels, it does not use any medium such as carbon ribbon, but directly heats the print head to generate a chemical reaction on the thermal paper to generate graphics.
