“Compared to traditional solutions, the weight and material consumption of the box have been reduced by approximately 30%,” says Ilkka Harju, Packaging Services Director at Metsä Board. “The fresh fibre MetsäBoard Natural WKL Bright used for the box weighs 80 g/sqm. All the corrugated board layers are made of the same material, which makes the production logistics efficient too”
“Here in the Nordics we are committed to producing high-quality products while living in harmony with nature,” says researcher and an expert on ECG Expanded Gamut printing Dr Kai Lankinen, which provided consultation on the graphic design, prepress, and flexographic printing requirements.
“What sets this project apart is the focus on the entire cycle of the product, beyond just the liner board material, with a special emphasis on printing quality, efficiency, and sustainability.
“To achieve this goal, Metsä Board brought together professionals from various domains to collaborate. In the design phase, the team took into account the possibilities and requirements of flexographic printing, which lead to excellent print result, even though this is an uncoated paper stock.”
The visual outlook of the pizza box was designed by Futupack and the packaging was manufactured by Adara Pakkaus. Metsä Board provided a fully bleached, uncoated white kraftliner suitable for any type of printing. The box reproduces a high quality CMYK image. Traditionally this was not possible and images were printed with fewer line colors. The high whiteness of the material provides high print contrast and detailing of the picture.
Once the new pizza box was created, Metsä Board’s Sustainability Service compared the packaging to existing solutions and made an analysis of its environmental impact by looking at both the material and the production. As a result, compared to traditional recycled cardboard packaging, the weight of the fresh fibre pizza box made of MetsäBoard Natural WKL Bright was up to 38% lighter and its carbon footprint up to 50% lower.
