Pioneering sustainable packaging technology with PulPac

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 products and will now add dry molding to our portfolio. With this investment, we support accelerating the commercialization 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.

“PulPac’s technology enables products that are highly sustainable, but the big benefit comes from scalability. Efficient production technology means there is a real potential for replacing single-use plastics at large scale,” Jonhed says. “Business viability for replacing plastics at scale is what makes the real difference.”


Which technology is the best, then?

“At Stora Enso we believe both wet and dry molding technologies will have a role in the future – different formed fiber solutions are optimal for different product segments. We will keep pioneering the best technologies on the market. Our ambition level is sky high when it comes to finding the most sustainable, economically viable alternatives for single-use plastics” Jonhed says.
