• Chemical Pulping: Utilizes chemicals to dissolve lignin, separating fibers more effectively. It produces greater quality pulp but is more expensive.

3. Blending and Refining

In this phase, the pulp is mixed with additives such as fillers, colorants, and sizing agents. The mix is fine-tuned to improve fiber bonding and produce the preferred paper properties, such as opacity and smoothness.

4. Sheet Formation

The refined pulp is spread onto a mesh screen to form sheets. The water is drained pipes, and the pulp begins to take the shape of the paper. This procedure requires precision to make sure a constant thickness.

5. Drying

The formed sheets are gone through heated rollers to get rid of excess moisture. This step is essential for accomplishing the last texture and quality of the paper.
