Pioneering sustainable packaging technology with PulPac

Consumers want products that enable them to lead more eco-friendly lives. This means minimising waste, carbon footprints and reducing the use of plastic. Stora Enso is responding to these needs with renewable packaging innovations, including formed fiber, a renewable and recyclable material that enables molding 3D shapes from wood fibers.

“We are finding growth in sustainable and innovative packaging. To stay ahead of the curve, we are investing in next generation fiber molding technologies,” says Anna Jonhed, SVP Formed Fiber at Stora Enso.

Recently Stora Enso became a shareholder of PulPac, a Swedish sustainable packaging technology company working to establish Dry Molded Fiber as the next global standard for sustainable packaging, replacing single-use plastics with circular fiber solutions.

Dry molding of fibers is a process that uses dry raw materials, while wet molding involves mixing pulp in water to a low concentration. Dry molding comes with many sustainability benefits, including energy efficiency, a lower carbon footprint and less need for water. It is also a very efficient production method with high product output and scalability.

“We are currently using wet molding in our production and will now add dry molding to our portfolio. With this investment, we support accelerating the commercialisation of PulPac’s technology and serve our customers with a wider range of sustainable fiber technologies,” Jonhed says.

PulPac uses a licensing model, where customers, for example packaging converters, get access to their patented technology while both materials and production equipment are provided through other partners. This model enables a rapid scale up of production capacity, and PulPac’s target is to replace 1 million tonnes of single-use plastics by 2025.
