Containerboard Prices Flat in October After September Increase

Containerboard prices held flat in October, following a price increase that took hold in September.

The October plateau ends two consecutive months of movement on the grade. Industry pricing sources confirmed no new numbers posted last month.

What happens next?

Sources anticipate the implementation of containerboard producers' third round of price increases in 2026 will continue into next year. Some analysts predict another hike in the coming months.

That would mark a fourth round of increases within roughly a year, if producers move again. Buyers have already absorbed two completed rounds plus one partially implemented round in 2026.

For marketers and packaging-dependent brands, the October flat print offers a brief window. Procurement teams tracking paperboard costs can use the pause to lock in contracts before any additional producer action lands.

The analysts' forecast of another near-term hike keeps pressure on packaging budgets heading into 2027 planning cycles.
