Metsä Board is launching a new eco-barrier paperboard. This new, innovative paperboard with a special barrier treatment is bio-based, recyclable and biodegradable, and developed especially for food service use. On top of the sustainability benefits of this new product it also offers efficiencies in printing and converting.
There is a clear market need to develop paperboards with bio-based barriers as alternatives to fossil-based barriers. The new eco-barrier paperboard, MetsäBoard Pro FSB EB1, is a unique product with a bio-based and biodegradable special barrier treatment that is fluorochemicals-free. The new eco-barrier paperboard can be used with foods requiring grease resistance up to KIT level 5, and the barrier properties can be further improved by adding varnishing layers at the converter. This latter option offers a notable increase in efficiency as the barrier property improvement can be made by applying only one varnishing layer in comparison to paperboards without this special barrier treatment.
