Thermal barrier coating for non-top-coated (ntc) paper

Abstract

A novel barrier coating for non-top-coated (NTC) phenol-free direct thermal paper enhances humidity resistance while maintaining cost-effectiveness and environmental sustainability. The coating atop the thermal-sensitive layer protects against moisture and high heat conditions, preserving image quality and density. Comprising a specific formulation of hard and soft film-forming acrylic emulsions, the barrier coating melts during printing, ensuring non-interference with thermal image formation. This innovation addresses limitations of traditional top-coated papers, offering improved performance without increased costs or environmental impact. The coating process involves precise application and drying techniques, resulting in a product that balances humidity resistance, print quality, and eco-friendliness for various applications, including labeling, ticketing, and receipt printing.
