Thermal paper is a label paper specially used on thermal printers. Its quality directly affects the printing quality of barcode printing software and the shelf life of labels, and even affects the life of the printer.
Thermal label paper is a specially treated label paper with high thermal sensitivity. Thermal label paper is usually divided into three layers. The bottom layer is the paper base, followed by the thermal coating and protective layer.
The thermal layer and protective layer are the main reasons affecting the quality of label paper. If the coating of thermal paper is uneven, some places will be dark in color and some places will be light in color when printing labels with barcode printing software, and the printing quality will be significantly reduced. If the formula of the thermal coating is unreasonable, it will affect the shelf life of the label paper.
The protective coating of thermal label paper is an important factor in ensuring the shelf life of label paper. It can absorb part of the light that causes the chemical reaction of the thermal coating, slow down the deterioration of the printing paper, and protect the printer components from damage.
Good thermal label paper can be stored for 5 years or even longer after printing. However, if the thermal coating is not properly treated, it may only be stored for a few months.
The material characteristics of thermal label paper are non-waterproof, oil-proof and tearable. It is widely used in shopping malls, electronic scales, cash register printing paper, commodity price tags, frozen fresh food, chemical laboratories and so on.
