Greif will increase prices for all grades of uncoated recycled paperboard by $60 per short tonne.
In addition, tube, core and protective packaging products will see an increase of at least 6.5%.
The change for uncoated recycled paperboard applies to new orders and deliveries from 6 July 2026.
For tube, core and protective packaging products, the higher pricing takes effect for shipments from 13 July 2026.
According to Greif, the paperboard increase reflects higher raw material and freight expenses, together with growing demand for these products.
The increase said the rise for tube, core and protective packaging products follows increases in paperboard and adhesive costs, which are the main inputs used in those products, as well as higher transport expenses and stronger demand in the markets it supplies.
