Product Description
Thermal paper
It is a special fine paper that is coated with a material
formulated to change color when exposed to heat. It is used in
thermal printers, particularly in inexpensive or lightweight
devices such as adding machines, cash registers, and credit card
terminals.
The surface of the paper is coated with a solid-state mixture of dye and a suitable matrix; a combination of a fluoran leuco dye for example. When the matrix is heated above its melting point, the dye reacts with the acid, shifts to its colored form, and the changed form is then conserved in a metastable state when the matrix solidifies back quickly enough. The reactant acid in thermal paper is often bisphenol A (BPA).
Usually, the coating will turn black when heated, but coatings that turn blue or red are sometimes used. While an open heat
source, such as a flame, can discolor the paper, a fingernail swiped quickly across the paper will often generate enough heat from friction to produce a mark. Multicolor thermal paper first became available in 1993 with the introduction of the Fuji Thermo-Autochrome (TA) system.[1] This was followed in 2007 by Polaroid's development of the Zink ("zero-ink") system.[2] Both of these methods rely on multi-layer coatings with three separate colorizing layers, with different methods used for independent activation of each layer.

FAQ
Since we built more than 30 successful production lines and
exporting lots of machines in South America, Asia, Africa, Europe ,
etc., more customers desired to visit us personally, not only check
capacity but also to see our machines how to work and paper quality
made by them, so 15 years ago we built paper factory by machines
and production lines we produced and designed. Right now, our own
lines focus on producing carbonless papers (NCR) and thermal
papers, however, we only produce top grade papers for showing our
machines and technologies better.
