Description

Technical Field

[0001] The invention relates to the technical field of printers, in particular to a thermal label printer without liner. Background Art

[0002] Traditional label paper is composed of two parts: label and release liner. During use, information is printed on the label paper through a printer, and then the label is peeled off the liner and pasted on the packaging surface. The remaining release liner is treated as waste. Due to the extremely developed current science and technology information, label printers are widely used, especially in the logistics industry. When using traditional label paper, a large amount of release waste paper is also generated accordingly. Compared with traditional label paper, linerless labels directly roll the glued label paper into a roll. After the label is printed, it can be directly pasted on the packaging box, which not only saves the material of the liner, but also reduces the cost of the label paper. In addition, the linerless label has a strong adhesive backing, and it is very easy to stick to the objects it touches, resulting in paper failure, so the design requirements of the printer are extremely high.
