Phenol-free thermal paper refers to thermal paper that is free of BPA and BPS and realizes printing effects through purely physical reactions.
In the classic process of traditional thermal paper production, chemical substances such as color developers or color development agents are often used. In particular, BPA, as an organically synthesized chemical substance, has been widely used as a color developer. These chemicals undergo changes when faced with thermal stimuli, resulting in clear images. Because BPA is considered to have negative health effects, manufacturers are actively seeking alternatives to produce more environmentally friendly and health-friendly thermal papers, For example, thermal paper with BPS instead of BPA, but thermal paper with BPS has the same environmental and health problems.prompting the emergence of bpa-free and bps-free thermal papers.
What is BPS Free Thermal Paper?
BPS is an excellent color developer. It is used as a substitute for bisphenol A. It is widely used in the field of thermal recording paper (e.g. thermal recording paper, ECG paper, fax paper, etc.)
How does phenol-free thermal paper work?
Phenol-free thermal paper not only replaces traditional thermal paper, but also completely eliminates chemicals and chemical coatings. This paper does not add any color developers and completely realizes a purely physical reaction without any chemicals. This innovation is not only an important development for the industry, but also provides users with a safer and more environmentally friendly option.
Phenol-free thermal paper has a multi-layer structure that includes elements such as a protective layer (optional), a functional layer, a black coating and a base paper to ensure a clear and long-lasting image during the printing process.
Phenol-free thermal paper working principle: by adjusting the temperature, the originally opaque functional layer becomes transparent, so as to achieve the printing effect.
Benefits of Phenol-Free Thermal Paper？
This new patented technology thermal paper is innovative without the use of chemicals called developers or developer fluids. Its unique blue-gray image shows advanced color expression.
Phenol-free thermal paper is certified for direct food contact, demonstrating its safety.
The paper's medium sensitivity and high image stability during printing ensure that images will not fade for at least 35 years.
The sustainability of this thermal paper is also demonstrated by its recyclability, which further reduces its environmental impact and sets a new benchmark for the industry in terms of environmental protection and user health.
Phenol-free thermal paper is compatible with common thermal POS printers, providing users with a sustainable, high-quality printing solution!
