Every now and then we dive deeper into the details of paper making by highlighting a certain part of the process. This time we are focusing on calendering, which is one of the crucial steps in achieving Multicopy’s excellent print results.
Calendering is the process by which the paper’s surface is altered to achieve a smooth finish – improving its printability properties. If not calendered, many printing papers simply wouldn’t measure up to the required printing quality. Our uncoated grades, like the office papers in the Multicopy family, manufactured at Nymölla Mill, are treated through a soft nip calendering process.
The soft calendering machine uses heat, pressure and friction to produce the required result as the paper web is pressed through two “rolling” nips. These soft rolls have an elastic cover that form a nip, replicating the surface of the tempered roll with a hard surface – that is where the smoothness is created.

Some people and organizations argue that old forests are more sustainable than new ones, no matter how responsible the forestry and harvesting. That any company who uses wood for its products is causing a major negative impact on our climate – when it comes to reduction of carbon emissions and the biodiversity of our forests. But it’s not a black and white question. As a matter of fact, there are several upsides to harvesting and managing forests to get a hold of the remarkable, renewable raw material called wood.
Alongside Gasum’s biogas plant at Nymölla mill, another sustainable initiative is in the making. All over the world, the demand for sustainable textile fibers is growing and the new facility is a demonstration plant for TreeToTextile, owned by Stora Enso, H&M Group, Inter IKEA Group, and LSCS Invest.
Gasum’s biogas plant at Nymölla Mill is now producing liquefied biogas (LBG) at full speed. We created an icon that communicates the benefits in a clear way; how we manage to, not only make use of residue from the process of turning wood into paper, but also make way for a fossil free future.
