Calcium carbonate (CaCO3) powder is widely used today as a filler and coating material in the paper manufacturing industry. It is the most important filler and coating material due to its abundant natural occurrence and low cost, as well as its higher whiteness compared to other alternatives such as kaolin and clay.

The advantages of using CaCO3 powder in paper production.
- In a typical paper production environment that is often acidic, the use of calcium carbonate as a neutralizing agent is very beneficial for paper production.
- The calcium carbonate filler and coating will have higher whiteness, gloss, and good printing ability with competitive prices.
- Calcium carbonate can be used in large quantities and the amount of wood pulp can be reduced without affecting the strength of the paper.
- High-speed papermaking machinery can operate at higher speeds and complete the paper drying process faster, these improvements save energy costs.
The application of Calcium Carbonate (CaCO3) powder in paper production.
Calcium Carbonate Powder (CaCO3) – Accounts for 20% of the structure in the paper manufacturing industry, including types of paper such as Ford, Couche, Bristol, Duplex, Ivory, gold-plated paper, etc.
Calcium Carbonate as a filler in paper:
Calcium Carbonate (CaCO3) is applied as a filler in paper production, such as writing paper, printing paper, packaging paper, and hardcover book paper. The use of calcium carbonate as a filler in paper has advantages over non-filled paper, such as a smoother surface, higher brightness, gloss and improved printability.
Calcium carbonate as a coating material in paper:
Calcium Carbonate (CaCO3) powder as a coating material improves the surface quality of paper, making it stiff and provides an even surface, which enhances the printing process.
