What Is Thermal Paper?

Thermal paper is a special paper that develops images when heated by a thermal printhead, without needing ink, toner or ribbons.
As the thermal head heats specific areas of the paper surface, the thermal coating reacts and forms text, barcodes or graphics – this is how most receipts and tickets are printed.

sailinglabel is a thermal paper manufacturer based in Dongguan,Guangdong, supplying various grades and sizes of thermal paper for receipts, tickets and label applications.

Basic Structure of Thermal Paper

A sheet or roll of thermal paper usually consists of several layers:

  • Base paper – provides strength, thickness and stiffness, acting as the “backbone”
  • Revestimento térmico – contains the color-forming system that reacts to heat
  • Pre-coat or undercoat (depending on the design) – improves coating adhesion and image uniformity
  • Topcoat or protective layer (when needed) – enhances resistance to abrasion, dirt and environmental factors

For different applications, the structure and formulation of these layers are adjusted to balance cost, print quality and image life.

How Thermal Paper Works

The working principle of thermal paper can be summarized as:

  • The thermal coating contains colorless dye and a developer
  • The thermal printhead generates localized heat where the image should appear
  • In heated areas, the dye and developer react and form visible dark images
  • Unheated areas remain white or light, creating contrast

As a result, image quality depends heavily on the sensitivity, uniformity and protection of the thermal coating.
