Thermal Label：

A thermal label paper roll is a label manufactured using thermal paper coated with a heat-sensitive material. When printing, a thermal printer prints the image or text directly onto the label by heating the print head without the use of ink or ribbon. Rollo thermal labels are widely used in retail, logistics, transportation and healthcare, and are commonly used to print barcodes, price tags, courier documents and product labels. Their features include fast printing, easy operation and clear label print quality.
