Greif on Tuesday became the second major uncoated recycled paperboard producer within the last week to announce a price increase, after Sonoco on March 6. Cascades was the first with such an increase in 2026, and its early February announcement came simultaneously with a $70 per ton containerboard price hike. Ox Industries, the third largest North American URB producer, also announced a $70 per ton URB price increase as of April 6, Fastmarkets RISI reported.
