Lightweight, without loss of strength. Holmen INNR is the key to climate-smart packaging.ORDER SAMPLE PACK
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 9 to 16 percent paper.
Less weight also means less carbon footprint. Holmen INNR has an impressively low carbon footprint compared to the average semi-chemical or recycled-based fluting on the market. You can see some calculation examples below, and learn more about how you can lightweight your products. We push the boundaries for what's possible.
Lower the weight of the box by using containerboard components that are sturdy for their weight. Light-weight fluting works thanks to the relative stiffness and elasticity of all individual wood fibres. The fibres are mechanically separated in the production process, and the result is a fluting medium that is lighter, but still strong and stable.
Holmen INNR is certified for food contact. With its smooth and even surface it runs well through both the corrugating and converting machines, and it reacts well to gluing. It's the perfect containerboard component.
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. By using Holmen INNR in all the inner layers of a double or triple-wall containerboard, both as fluting and interliner, you will truly see the lightweighting effect. We can help you calculate the difference, find your contact below.
Since interliner is a relatively new product, you may ask what it is, and why it is 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 will not only lower the total weight of your product, you will also reduce the carbon dioxide emissions. Learn more about interliner.
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.
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, is free to download.
Calculate with the amount of tonnes you need, compare to the carbon footprint of the paper you have used before, and see the difference. We can help you calculate, if you would like. This is how we at Holmen Paper work to reduce your containerboard CO2 emissions.
By switching to a lightweight 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 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.
