PulPac has announced that its intellectual property portfolio within dry-moulded fibre (DMF) has exceeded 500 national patent grants worldwide.
The company linked the development to wider acceptance of DMF as a manufacturing process, rather than as a nascent alternative.

PulPac noted that fibre forming has long been led by wet-based production methods, adding that DMF is increasingly being adopted as a fibre forming process that can be used at an industrial scale.
Its patent holdings cover areas, including fibre preparation, tool design, and built-in functional elements.
PulPac said the total of more than 500 granted patents follows years of engineering work and process development.
It has invested close to 800,000 research and development hours in DMF.
The group also said that an industrial rollout is being supported by a network of machine manufacturers with experience in injection moulding, non-wovens, fibre processing, and packaging automation.
Work within that network, including broader DMF platform functions, is supporting wider use across different markets.
PulPac chief operating officer Viktor Wingård Börjesson said: “Dry moulded fibre 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.
“The intellectual property platform and engineering experience we have built over the past decade provide a stable foundation for companies investing in dry moulded fibre, and that is increasingly reflected in the level of industrial engagement we are seeing.”
Last month, the company said that it is working on a new range of fibre-based caps using its DMF technology.
Those caps will be shown publicly for the first time at the interpack 2026 trade fair, due to run from 7 to 13 May in Düsseldorf, Germany.
