| Raw Material | Description |
|---|---|
| Virgin Pulp | Obtained from fresh wood, guaranteeing high quality and brightness. |
| Recycled Pulp | Made from post-consumer paper waste, decreasing environmental impact. |
2. Pulping
The procured raw products are converted into pulp. This procedure can be done in 2 main methods:

| Lightening Method | Description |
|---|---|
| Chlorine Bleaching | An effective approach but less environmentally friendly. |
| Oxygen Bleaching | A more eco-friendly alternative that decreases chemical use. |
4. Papermaking
The bleached pulp is watered down with water and sent to a paper machine. Here, it is spread out onto a moving wire screen, where excess water is gotten rid of, and the pulp fibers bond together to form a sheet.
5. Drying and Finishing
When the sheet is formed, it is passed through a series of heated rollers that eliminate the remaining moisture. After drying, the paper undergoes numerous completing procedures, such as calendaring (smoothing) and cutting.
6. Quality assurance
