13 Apr. 2026: Sweden-based PulPac has surpassed 500 national patent grants worldwide for its Dry Molded Fiber technology, a milestone that reflects the process’s growing industrial adoption in fiber-based packaging manufacturing. 

For decades, fiber forming has largely relied on wet molding techniques. Today, the category is expanding as Dry Molded Fiber gains recognition as a scalable production method.

“Dry Molded Fiber is no longer an experimental technology. It is an industrial category in its own right, and we are seeing the market move from curiosity to commitment,” said Viktor Wingård Börjesson, Chief Operating Officer at PulPac.

According to the company, its intellectual property portfolio covers several stages of the process, including fiber preparation and airlaying, forming and pressing techniques, tooling configurations and integrated functional features. Surpassing 500 national patent grants strengthens PulPac’s position as a leading intellectual property holder in industrial dry fiber forming.

The milestone reflects more than a decade of engineering work. PulPac reports that its teams have invested close to 800,000 hours in research and development related to Dry Molded Fiber. This accumulated experience helps reduce uncertainty for manufacturers considering industrial implementation.

Industrial deployment is also supported by PulPac’s network of machine builders. The ecosystem brings together companies active in injection molding, nonwovens, fiber processing and packaging automation. Together, these partners are developing production platforms for large-scale fiber-based packaging manufacturing.

These developments suggest Dry Molded Fiber may be approaching broader market adoption. Growing engagement from machine builders and regulatory developments such as the Packaging and Packaging Waste Regulation are contributing to increased interest in fiber-based alternatives.

Rather than replacing existing production methods outright, Dry Molded Fiber is increasingly implemented alongside plastic conversion and traditional wet molded fiber production. According to PulPac, this parallel approach lowers barriers to adoption and supports gradual industrial scale-up.

PulPac develops Dry Molded Fiber, a technology designed to enable high-speed production of rigid fiber packaging while reducing resource consumption. The technology is deployed globally through a network of partners and licensees, with the company aiming to accelerate the transition from single-use plastics to fiber-based packaging solutions.
