The thermal coating or protective layer mainly affects its quality. If the coating of the thermal cash register paper is not uniform, printing will result in different shades of color; if the chemical formula of the thermal cash register paper’s coating is unreasonable, the storage time of the thermal cash register paper after printing will be shortened. The protective layer is also critical to the storage time after printing.
