Metsä Board will begin live testing of foam forming on a production scale at its Kyro mill in Finland. The company has already done extensive development work for years to commercialize the new technology.
According to Metsä Board, by using foam forming, the paperboard structure becomes bulkier, lightening the board's weight.
In addition, fibers are distributed more evenly in the web, improving formation of the board and resulting in more consistent properties and appearance.
On top of the above-mentioned benefits, the technology reduces the use of raw materials, energy and water, enhancing sustainability, Metsä Board added.
"We have already seen that the technology works in a laboratory environment as well as on pilot machines," said Mika Joukio, CEO of Metsä Board. "Following promising laboratory scale results and our detailed feasibility studies, we reached a decision to invest in further development of the technology on a production machine. Our target is to offer our customers even more efficient and ecologically sound paperboards in the future."
Metsä Board is a forerunner in developing the foam forming technology. The company has been undertaking research as part of the Finnish Bioeconomy Cluster FIBIC's research programs which have been successfully scaled up together with VTT Technical Research Centre of Finland. Different phases of research and development have been accelerated through funding support from Tekes, the Finnish Funding Agency for Innovation.
