Kraft linerboard hit $1,090-1,170/mt this week with producers pushing $50-70/t June hikes across North America. European sack kraft markets are under dual pressure from Mondi's Steti mill closure and energy cost inflation from the Strait of Hormuz disruption. Packaging buyers face the tightest supply conditions since 2022 with no relief expected before Q4 2026.
Kraft paper markets are in a structural upcycle driven by capacity closures and rising input costs.
North American linerboard at $1,090-1,170/mt with successful June price hikes expected to hold.
European sack kraft faces supply contraction as Mondi Steti closure removes 220kt of capacity.
Lock in H2 volumes before Q3 price announcements; European buyers should secure non-EU alternatives.
Rzzro Intelligence · Industrial Materials · Week 6 Jun 2026
Kraft paper markets entered June 2026 with a clear bullish bias. North American producers announced $50-70/t increases effective June 1, following successful Q1 and Q2 rounds. Fastmarkets assesses 42-lb unbleached kraftliner at $990-1,000 per short ton delivered US East, equivalent to approximately $1,090-1,100/mt (FACT). The June increases could push levels to $1,140-1,170/mt if fully realized (ESTIMATE).
Supply dynamics are tightening. Mondi's Steti mill in the Czech Republic permanently closed its kraft paper line in early 2026, removing approximately 220,000 tonnes of sack kraft capacity from the European market (FACT). In North America, multiple smaller mills have idled machines or shifted to specialty grades, reducing virgin kraftliner output by an estimated 3-5% since 2024 (ESTIMATE).
Demand remains supported by e-commerce packaging growth at 1.5-2% annually and industrial sack demand in construction and chemicals (ESTIMATE). However, rising energy costs from the Strait of Hormuz disruption are increasing production costs at integrated mills, particularly in Europe where natural gas prices directly impact pulp and paper manufacturing (FACT).
Mondi Steti mill closure removed 220kt of European sack kraft capacity. Additional machine idling across North America (at least 3 mills since 2024) has reduced available virgin kraftliner supply. Global capacity utilization rates are estimated at 85-88%, above the 10-year average of 82%. (FACT)
The Strait of Hormuz disruption has pushed European natural gas prices to multi-year highs. Integrated pulp and paper mills in Europe are particularly exposed, with energy representing 15-20% of kraft paper production costs. North American mills benefit from lower natural gas prices but face rising recovered paper costs. (FACT)
North American producers announced $50-70/t June increases across all virgin kraftliner grades, following successful Q1 ($40-60/t) and Q2 ($50-70/t) rounds. Implementation rates have been 70-90% in recent quarters, suggesting the June round will largely hold. European producers are expected to follow with $40-60/t increases for July. (FACT)

Kraft linerboard prices at $1,090-1,170/mt with June hikes expected to hold. Domestic demand supported by e-commerce (Amazon, Walmart driving corrugated demand) and industrial packaging. Supply constrained by mill closures and grade shifts. IP, Smurfit WestRock, and PCA are operating at near-full utilization. Risk: potential demand softening if US consumer spending slows in H2. (FACT)
European sack kraft market under severe pressure. Mondi Steti closure removed 220kt of capacity, tightening the market significantly. Testliner and recycled grades face less supply pressure but higher energy costs. Natural gas prices at multi-year highs are squeezing integrated producer margins. Expect European producers to announce increases of 40-60 EUR/t for July. (FACT)
Asian testliner and kraft paper markets are more competitive with FOB Vietnam testliner at approximately $525/mt. Chinese domestic producers are operating at 80-85% utilization with ample supply for domestic demand. However, rising OCC (old corrugated containers) prices are pressuring recycled mills. Export markets face freight cost headwinds from Middle East disruptions. (ESTIMATE)
Kraft Linerboard (virgin) - Delta vs Q1 2026: +8-10%. Drivers: June price hikes, mill closures, strong corrugated demand. Pass-through lag: 4-6 weeks. Exposed spend: corrugated box buyers, e-commerce packaging, industrial shipping. (FACT)
Sack Kraft Paper - Delta vs Q1 2026: +10-12%. Drivers: Mondi Steti closure, European energy costs, tight supply. Pass-through lag: 6-8 weeks. Exposed spend: cement, chemical, and agricultural bag buyers. (ESTIMATE)
Testliner / Recycled - Delta vs Q1 2026: +3-5%. Drivers: OCC price increases, energy costs, partially offset by ample recycled fiber supply. Pass-through lag: 4 weeks. Exposed spend: lighter-duty packaging buyers. (ESTIMATE)
| Annual Spend | Delta | Annual Impact |
|---|---|---|
| $1M | +8% | $80,000 |
| $5M | +8% | $400,000 |
| $10M | +8% | $800,000 |
| $50M | +8% | $4.0M |
Full implementation of June hikes ($50-70/t) with no demand softening. European producers successfully pass energy costs. Q3 average: $1,150-1,200/mt kraft linerboard.
June hikes partially implemented (70-80%). European mills announce 40 EUR/t increases. OCC costs rise 5-8%. Q3 average: $1,090-1,150/mt with gradual tightening.
Full June hikes plus additional $40/t July announcements as energy costs spike. Further European mill closures. Supply shortages in sack kraft. Q3 average: $1,200-1,300/mt.
