At Norske Skog Golbey, we will manufacture the paper pulp for our containerboard ourselves.
Thanks to our experience in newsprint manufacturing, we know that producing our own paper pulp will allow us greater flexibility and control over our supply chain.
To make our paper pulp, we will recycle 610,000 tonnes of old corrugated containers. This is equivalent to about 15% of the French supply.

Following the conversion of one of its newsprint machines, our mill will have one of the most efficient containerboard machines by 2024.
The process of making containerboard involves the same basic steps as newsprint:
Forming the sheet by mixing short and long fibres – pressing it – drying it
For the production of the testliner (used as the outer layers of the corrugated boards), two additional steps have to be added to the manufacturing process to optimise the quality of the final product: applying a starch and then drying it to increase the strength of the paper.
In the next few years, we hope to reach production capacity of 550,000 tonnes of containerboard per year.
PM 1
Machine length: 190 to 200 m
Machine width: 9.3 m
Speed: 96 to 102 km/h
Weight of a mother reel: 74 tonnes
Width of a mother reel: 8.8 metres
Finishing consists of cutting a mother reel of paper into smaller reels according to the dimensions required by our customers.
As soon as the conversion of the line is complete, we will have an automated winder that takes the sheet, cuts it to the required size and winds it fully automatically.
It will then be labelled by our robot to ensure traceability. Our customers will thus have access to the key information about the reels: weight, grammage, width, etc.
After labelling, the reel passes along a conveyor to the warehouse for storage.
Weight of a cutter reel: 1 to 4 tonnes
Width: 0.50 to 3.35 metres
Reel diameter: 1.4 m
Winding speed: up to 180 km/h
To store our containerboard reels, we have built a new 7,500 m² warehouse. It will be fully automated using tried and tested technology. Automated overhead cranes will move and store the reels using a vacuum grip system. This will ensure the safety of our employees as well as the quality of the finished products.
At shipping time, a conveyor system will transport the reels to the loading dock, where they will be transferred to the lorries by our teams.
Thanks to a conveyor that connects this new warehouse to the warehouse already used for newsprint reels, we will also be able to send our containerboard reels by train.
Dedicated warehouse
Area: 7,500 m²
Number of lorries shipped: about 100/day
Possibility of rail transport: 4.5 km of railway track on site
What is containerboard?
Containerboard is a paper that is used by corrugators to make corrugated sheets. Depending on its technical characteristics, it can be used to form the fluting or the outer layers of the sheet.
What can containerboard be used for?
Containerboard is mainly used to form sheets which will themselves be used to make corrugated boxes, fruit and vegetable crates, shop displays or even designer furniture… But it can also be used without transformation, particularly to cushion parcels instead of other materials (plastic, polystyrene etc.).
What makes it an environmentally friendly product ?
Like all paper, containerboard is part of the circular economy, as its raw material is composed by old corrugated containers and material. According to an Austrian university study, the fibre from used corrugated materials could be reused up to twenty times. Thoughtful, responsible use of resources means we can guarantee respect for the environment.
