Process
At Nepal Paper and Pulp Industries, recovered paper is transformed into quality paper products through a controlled recycling process. From sorting and pulping to cleaning, paper formation, finishing and dispatch, every stage is managed to produce reliable paper for writing, printing, copier and related paper uses.
Recovered Paper Collection & Sorting
We begin by selecting and sorting recovered paper to prepare a clean and reliable raw material base.
- Recovered paper is checked for grade, cleanliness and suitability.
- Unsuitable materials are separated before production.
- Good sorting supports cleaner pulp and consistent paper quality.
Pulping
The sorted recovered paper is converted into pulp slurry, preparing the fibers for further processing.
- Sorted paper is mixed with water and converted into pulp slurry.
- The process separates paper back into usable fibers.
- A steady pulp supply prepares the stock for cleaning and quality improvement.
Cleaning & Screening
The pulp passes through cleaning and screening stages to remove impurities and improve fiber quality.
- The pulp is cleaned and screened to reduce unwanted materials.
- This stage improves pulp cleanliness before paper formation.
- It helps protect downstream equipment and supports better surface quality.
Deinking & Brightness Improvement
Ink and color impurities are reduced to make the pulp cleaner, brighter and suitable for quality paper production.
- Ink, dirt and color impurities are reduced through controlled treatment.
- This helps improve brightness and cleanliness for writing, printing and copier grades.
- The focus is on stable appearance and consistent paper quality.
Paper Formation
Prepared pulp is formed into a continuous paper sheet on the paper machine.
- Prepared pulp is evenly distributed on the paper machine.
- Fibers form a continuous wet sheet as water drains away.
- Uniform formation supports stable GSM, surface quality and runnability.
Pressing, Drying & Surface Finishing
The paper sheet is pressed, dried and surface-finished to achieve required strength and printability.
- Water is removed through pressing and drying sections.
- Surface finishing improves strength, smoothness and printability.
- This stage gives the sheet its final feel and usable paper properties.
Reeling, Cutting & Conversion
Finished paper is reeled and converted into reels, sheets or copier paper packs as required.
- Finished paper is wound into reels for handling and conversion.
- Reels are converted into sheets, rolls or copier/A4 packs as per requirement.
- Accurate cutting and finishing prepare the paper for market use.
Quality Testing, Packing & Dispatch
Every finished product is inspected, packed and dispatched with care to ensure customer satisfaction.
- Final paper is checked for key quality and appearance requirements.
- Products are packed to protect against moisture, dust and handling damage.
- Finished goods are labelled and dispatched according to customer orders.
