Thermal paper is actually thermal printing paper, thermal fax paper, used in thermal printers and thermal fax machines. Its quality directly affects print quality and storage time, and even affects the service life of printers and fax machines.
In terms of structure, thermal printing paper is generally divided into three layers, a paper base layer, a heat-sensitive coating layer, a protective layer, a heat-sensitive coating layer and a protective layer have a great influence on the final effect. The more uniform the thermal coating, the more uniform the printed color and the better the visual effect. If the thermal coating is not uniform, the color will be different and the print quality will be degraded. The chemical formulation of the thermal coating directly affects the storage time of the printing paper. Long-acting thermal papers that can be stored for 10 years now appear. The protective coating acts as a name suggests. It absorbs some of the light that causes the thermosensitive coating to react chemically, protects the thermal coating, slows the deterioration of the paper, and protects the thermal elements of the printer from damage.
