Multiboard EcoKraft is one-sided 2-layer coated chipboard with kraft back side and additional glueing for moisture resistance. This board has good printing properties, excellent storage, high productivity on both sides of the printing and packaging line. Strong Nordic fibres make Multiboard EcoKraft one of the market’s strongest board qualities based on recovered fibre.
