Grenadier Packaging acquired MM Packaging Leeuwarden from Mayr-Melnhof Karton (MM) on 31 December 2025. Under Grenadier Packaging’s ownership, the Leeuwarden business will continue to operate as a dedicated standalone operation from its existing site in the Netherlands, with a clear focus on long-term stability and investment and full continuity of supply, product quality, and service for customers. MM Packaging Leeuwarden employs 52 people.

“We are acquiring MM Packaging Leeuwarden with a long-term view and a strong respect for the business that already exists. This acquisition represents a considered step in extending Grenadier Packaging’s footprint beyond the UK, allowing us to better support customers operating across European markets and to build a more resilient, diversified packaging group. Our focus remains on continuity – giving our support to the existing team, maintaining service levels, and investing responsibly over time,” said Aidan Cahill, joint managing director of Grenadier Packaging.

The Leeuwarden site will remain focused on its current product portfolio and customer base, with no immediate changes planned to day-to-day operations, management structure, or supplier relationships.

“Leeuwarden is a well-run, capable operation with clear strengths. Our priority through the transition is stability – ensuring customers, employees, and suppliers experience business as usual while the site benefits from the backing of a long-term owner,” said Ross Diamond, joint managing director of Grenadier Packaging.

All employees at the Leeuwarden facility are expected to transfer as part of the transaction, and all existing customer agreements will continue without disruption. Grenadier Packaging will engage closely with employees, works council representatives, customers, and suppliers throughout the transition period to ensure clarity and confidence, the company said.
