A new SEK100M reverse side coater will be used by Korsnäs to produce a white cartonboard to be launched in the first quarter of 2007.
“We have invested in the future with our reverse side coater,” says Frövi White project manager Ola Karlsson. “It is dimensioned to run the cartonboard machine much faster than is currently the case. Our development efforts are focused on gradually increasing the speed of the machine, meaning that bottlenecks must be handled through new investments. The cartonboard machine at Frövi is currently one of the largest and most modern in the world, and by purchasing it Korsnäs is demonstrating its intention to stay at the forefront in the future as well.
The majority of cartonboard production still has a brown reverse side even if Frövi Bright with its white quality has been on the market for about five years. It will be replaced by Frövi White, which is claimed to be even whiter and has a coated reverse side. The printing surface is said to be noticeably improved and smoother.
Although Frövi White will be the only Korsnäs product with a coated reverse side, the new coating unit will be used to treat other grades to improve reverse side smoothness.
Frövi White is also a stronger cartonboard than Frövi Bright. “We achieved this by using bleached long fibre pulp in the middle layer as well as bulky CTMP pulp,” explains Magnus Gyllenrapp, who is responsible for basic cartonboard development of the new grade.
Ola Karlsson concludes: “This is an enormous investment and we have created a niche for ourselves between fully bleached pulp and GC1 (reverse side coated FBB). An investment of this magnitude must be well substantiated. Market analyses have clearly indicated what customers want, and it is upon this knowledge that our development is based.”
