- Mechanical Pulping: Involves grinding wood logs to different fibers. This method is cheaper however may result in lower paper quality.
- Chemical Pulping: Utilizes chemicals to liquify lignin, separating fibers better. It produces higher quality pulp but is more expensive.
3. Mixing and Refining
In this phase, the pulp is mixed with additives such as fillers, colorants, and sizing agents. The mixture is improved to enhance fiber bonding and create the preferred paper homes, such as opacity and smoothness.
4. Sheet Formation
The refined pulp is spread onto a mesh screen to form sheets. The water is drained, and the pulp begins to take the shape of the paper. This process requires accuracy to make sure a consistent thickness.
5. Drying
The formed sheets are gone through heated rollers to eliminate excess wetness. This step is important for attaining the last texture and quality of the paper.
6. Completing
After drying, the paper undergoes numerous finishing processes, such as calendaring and cutting. The paper is then cut to A4 dimensions, packaged, and prepared for shipment.
7. Quality assurance
Throughout the production procedure, quality assurance procedures are carried out to ensure the final product meets industry standards. This includes screening for density, brightness, and tensile strength.
