Features of Carbonless Paper/NCR Paper
Multi‑Layer Structure
Carbonless paper is composed of multiple superimposed layers: the
back of the top sheet is coated with microcapsules containing
color‑forming dyes, while the front of each underlying sheet
carries a layer of developer colorants. When pressure is applied—by
handwriting, typing, or impact printing—the microcapsules burst and
release the dye, which reacts instantly with the developer on the
sheet below, creating a clear copy without the need for separate
carbon paper.
Color‑Development Principle
Under pressure, the microcapsules on the CB (coated back) layer
rupture, releasing dye that migrates onto the CFB (coated front
back) layer of the sheet beneath. A chemical reaction between the
dye and the developer produces a sharp, permanent mark. This
self‑contained system allows for faithful, multi‑part copying in
2‑, 3‑, or even 4‑part sets.
Environmental Safety
Modern carbonless papers are manufactured without harmful
substances and emit no unpleasant odors. Their dye and developer
systems are formulated to meet environmental standards, and
completed copies remain legible and fade‑resistant for over 15
years, making them suitable for archival use.
Exceptional Durability
Made from high‑quality base stock, carbonless paper has a smooth,
uniform surface that resists tearing and damage better than
ordinary paper. The coatings adhere firmly, ensuring consistent
copy quality even under heavy use.
Application of Carbonless Paper/NCR Paper
Medical field
The medical grade carbon-free paper is suitable for the special
needs of the medical industry, such as the reproduction of medical
records, inspection reports, etc., which has higher temperature
resistance, moisture resistance, chemical resistance and other
characteristics to meet the requirements of use in the medical
environment.
Education field.
In the educational scene, it can be used for the production of test
papers and other materials to achieve fast and accurate information
replication, which is convenient for the development of
examinations and other activities.
Emerging field.
With the continuous expansion of emerging fields, such as
e-commerce, distance education, etc., the application range of
carbon-free paper is also expanding, providing support for
documentation and information transfer in these fields.
