Adding wax lotion can effectively improve the hydrophobic property of the thermal paper coating and play a lubricating role

Thermal printing paper is an information paper that uses paper as a carrier and is coated with a thermal heating coating for thermal recording effect. Its application range is becoming increasingly wide, and the performance requirements are becoming higher. The structure of high-quality thermal paper is more complex

The thermosensitive layer is the key to thermal color development; The top coating is designed to provide waterproof, oil proof, and solvent proof functions for thermal paper; The bottom layer is used to improve the smoothness and insulation of the paper, while the backing layer is used to control the warping and penetration of the thermal paper.

Adding wax lotion to the top or back coating can effectively improve the hydrophobic property of the thermal paper coating, play a lubricating role, prevent the thermal print head from being bonded by the coating, reduce excessive wear, improve the wear resistance and smoothness of the coating, and thus provide high color strength; It can also reduce the friction coefficient between adjacent paper sheets, avoid the occurrence of strip phenomenon, and extend the storage period of thermal paper.
