Thermal cash register paper such as 80mm cash register tape wholesale is printed paper especially used on the thermal printer. Its quality has a direct impact on the printing quality and preservation time, even affects the life of the printer. Thermal silver register paper is generally divided into three layers, the bottom layer is paper base, the second layer is a thermal coating, the third layer is protective layer, which quality is mainly affected by the thermal coating or protective layer.

If the coating of the thermal silver paper is nonuniform, the printing will cause different colors; If the chemical formulation of the coating of thermal register paper is not reasonable, it will result in shorter storage time for thermal register paper after printing. The protective layer is also critical to the storage time after printing, which absorbs some of the light that leads to the chemical reaction of the thermal coating and slows down the deterioration of the thermal silver register paper.

Methods for distinguishing the thermal cash register paper: First, look at the appearance of the paper, the thermal silver paper with good quality has a uniform color, good smoothness, high whiteness, and a little green. If the paper is very white, the protective coating and thermal coating of paper are unreasonable, adding too much phosphor. If the finish of the paper is not high or looks uneven, the coating of the paper is uneven, and if the paper appears to reflect very strongly, also added too much phosphor.

Second, bake with fire and heat on the back of the paper, if the color on the paper is brown, it is shown that the heat-sensitive formula is not reasonable, and the storage time may be shorter. If the black part of the paper has small stripes or uneven color, the coating is uneven. The paper of good quality should be black and green after heating, and the color block is uniform, the color will gradually fade from the center to the surrounding.
