Raw Material
Description

Virgin Pulp
Derived from fresh wood, ensuring high quality and whiteness.

Recycled Pulp
Made from post-consumer paper waste, reducing environmental effect.

2. Pulping

The procured raw materials are transformed into pulp. This process can be carried out in 2 main methods:

• Mechanical Pulping: Involves physically grinding wood logs to separate fibers.
• Chemical Pulping: Uses chemicals to liquify lignin, producing a finer paper quality.

3. Lightening

If white A4 paper is the end objective, the pulp should undergo whitening. Chemical representatives are utilized to eliminate any residual color and impurities from the pulp.

Lightening Method
Description

Chlorine Bleaching
An efficient method but less environmentally friendly.

Oxygen Bleaching
A more eco-friendly alternative that reduces chemical use.

4. Papermaking

The bleached pulp is watered down with water and sent out to a paper device. 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 remove the remaining moisture. After drying, the paper undergoes different finishing processes, such as calendaring (smoothing) and cutting.

6. Quality assurance

Before the A4 paper is packaged for shipping, it undergoes rigorous quality assurance checks to ensure it meets the needed specs in terms of thickness, brightness, and texture.
