With wood fibre based packaging starting to replace plastic, it’s clear that the wood fibre will be an important raw material for a more sustainable tomorrow. As part of the Holmen group we at Holmen Paper have control over the entire supply chain. This means that we can guarantee 100% traceability of the product and ensure that it comes from a growing forest that is sustainably managed. And we have the certificates to prove it.
Fluting for light-weight containerboard
Our light-weight product range for containerboard has grown. Go lighter without losing strength. Holmen INNR is the key to climate-smart packaging.
Technical data sheetHolmen INNR changes the market from within
Holmen INNR is a fresh-fibre fluting medium and interliner paper for containerboard. Compared to traditional containerboard components, it is lightweight yet still strong. Holmen INNR 73 gsm is a great replacement for a standard recycled 80-85 gsm fluting paper. If you need 10 000 m2, you only have to buy 730 kg instead of 800–850 kg. That is a reduction of between 9 and 16 percent paper. Less weight also means less carbon footprint. Holmen INNR has an impressively low carbon footprint compared to the average recycled based fluting on the market.

How does light-weight fluting work?
Holmen INNR is a containerboard component that is sturdy for its weight. In the production process, mechanical separation of the wood fibres lets them keep their relative stiffness and elasticity. Allowing for a fluting medium that is lighter, but still strong and stable. We call this light-weight fluting. With its long fibres and smooth, even surface, the paper runs well through the corrugating and converting machines and reacts well to gluing.
The fluting is key for lightweighting packaging
When you calculate the weight of your end product, you will notice that changing the basis weight of the fluting has a big effect on the total weight. Especially when you design triple wall solutions. By using Holmen INNR in all the inner layers of a double or triple-wall containerboard, both as fluting and interliner, you can truly see the effect of lightweighting your containerboard components.
Why use interliner for containerboard?
What is interliner for containerboard, and why is it used? The interliner is a containerboard component that stabilizes the intermediate layers. It's a complement to the corrugated layers (fluting) and the liner. By using a light-weight interliner paper for the inner layers you can lower the total weight of your product, and reduce carbon dioxide emissions. Read more about the use of interliner here.
By using new Holmen INNR for the inside layers of your containerboard, you can reduce your environmental impact and lower the weight of your finished product. Open video on YouTube.
Get more square metres
Compared to a standard recycled fluting medium in 80 or 85 gsm you will get more surface area when buying one tonne of Holmen INNR.
1 tonne 85 gsm medium paper = 11,765 m2
1 tonne 80 gsm medium paper = 12,500 m2
1 tonne 73 gsm Holmen INNR = 13,699 m2
When switching to 73 gsm from 85 gsm you'll get 13,699-11,765=1,934 more square metres. Yes, that's 1.9 km more paper counting with a reel or sheet width of 1000 mm, or 1.2 km extra paper counting with a reel or sheet width of 1600 mm.
Lower carbon emissions
How much will switching to a 73 gsm Holmen INNR reduce the carbon footprint of your containerboard? You will need the supplier's carbon footprint declaration to sort this out. Our carbon footprint declaration, based on the CEPI framework, lets you compare and know for sure.
Calculate with the amount of tonnes you need, compare to the carbon footprint of the paper you have used before, and see the difference for yourself. We can help you calculate, if you would like. Or read more here about how Holmen Paper works to reduce your containerboard CO2 emissions.
Environmental data
By switching to a TMP-produced fluting medium like Holmen INNR, you will reduce both the weight of your finished board, and its carbon footprint. Carbon footprint is calculated as kilograms per tonne.
Carbon footprint INNR
Carbon footprint is defined as the total emissions caused by an individual, event, organisation, or product, expressed as carbon dioxide equivalent. Holmen Paper calculates the carbon footprint of our graphical paper products according to the ten toes of the framework set up by CEPI.

sustainability
We grow a sustainable future
At Holmen Paper we use the Holmen Group's greatest asset, the forest, to make innovative paper that breaks boundaries and challenges old perceptions. Through sustainable forest management and efficient production processes, we maximise growth and utilisation of the forest raw materials.
Our products are 100% recyclable and form the foundation for sustainable production and recycling. Pulp, paper and paperboard made from fresh fibre from Nordic forests play an important role in the European recovered fibre ecocycle. Since the ecocycle needs a constant injection of fresh fibre, without fresh fibre, there is no future recovered fibre.
