Thermal Paper Manufacturing Explained: A Complete Guide from Base Paper to Finished Rolls
SailingLabel’s Eco-Friendly Formulations and Multi-Layer Coating Technology for High Clarity and Long-Term Preservation
Visão geral do produto
Thermal paper is a specially coated printing paper widely used in POS receipts, ATM slips, medical records, tickets, and labels. Its core principle relies on a thermal coating that changes color when heated by the printhead, allowing for high-definition printing without the need for ink.
The surface of thermal paper is smooth, made from standard base paper coated with a thermal reactive layer on one side. This layer consists of adhesives, color developers, and colorless dyes (also known as leuco dyes). Without being isolated by microcapsules, the chemical reaction remains in a “latent” state until activated. When the thermal coating is heated by the printhead, the color developer and leuco dye react, producing a visible image of text or graphics.
Under high temperatures or direct heating by thermal components, the coating undergoes a chemical reaction between the developer and dye, generating the printed content instantly through thermal terminal devices.
As a leading thermal paper manufacturer in China, SailingLabel adopts BPA-free and BPS-free eco-friendly formulations. Backed by advanced flexographic printing and multi-layer coating production lines, every roll ensures high clarity, long-lasting preservation, and stable performance.
