Unions say machines idle and suppliers unpaid at Mutares-owned La Rochette Cartonboard

The CGT, FO and CFTC unions at La Rochette Cartonboard plan a rally on 19 September 2026 outside the French cartonboard plant, denouncing unpaid suppliers, raw material shortages and idled machines despite a full order book. The 255-employee plant, with revenue of around EUR 90m, has been owned by German investment fund Mutares since 2021 and was previously part of Italy's Reno de Medici group.
