The global kraft paper market entered the second half of 2026 with upward price momentum, particularly in Europe, where producers successfully pushed through mid-year price increases. Kraft paper averaged approximately $997 per tonne globally in Q1 2026, with European prices reaching $1,360 per tonne, according to Expert Market Research. The European premium reflects higher energy costs, carbon compliance expenses, and tighter virgin fiber supply relative to other regions.
The kraftliner segment — the largest component of the kraft paper market at roughly $29 billion in 2026 value — shows the clearest pricing signal. German kraftliner prices rose as announced increases largely took effect on June 15, 2026, with further edging up in early July on the containerboard market, according to EUWID. This follows a period of weakness in late 2025 when Q3 unbleached kraftliner prices across several trade routes declined 1-7%. The Producer Price Index for unbleached kraft packaging and industrial converting paperboard in the US reached 217.5 in June 2026 (December 1999=100), confirming that US pricing is also elevated by historical standards.
Sack kraft paper, used primarily for cement, chemical, and agricultural packaging, presents a slightly different picture. The global sack kraft market is valued at approximately $13 billion in 2026, growing at a 3.8% CAGR, according to Mordor Intelligence. Global trade prices for sack kraft averaged $940-960 per tonne in 2024, with rising pulp costs in mid-2026 (kraft pulp up 2.85% over the past month as of July 23) applying mild upward cost pressure for H2 2026. Unbleached sack kraft dominates trade at roughly 80% of global volume.
Demand is being driven by two structural forces: e-commerce and sustainability regulation. Multiple market reports agree that e-commerce packaging — corrugated shipping boxes, paper mailers, and sustainable filling materials — represents the fastest-growing demand segment for kraft liner and sack kraft. Global e-commerce continues to expand, and major online retailers are shifting toward fully recyclable kraft-based packaging solutions under pressure from plastic-reduction policies. The EU Single-Use Plastics Directive, carbon border adjustments, and extended producer responsibility (EPR) schemes are reinforcing this shift across Europe and increasingly in North America and Asia-Pacific.
The US market shows particular strength in heavy-duty sack applications. According to Fastmarkets, US multiwall sack shipments (cement and heavy-duty bags) rose 13.1% in 2025, with another 6.7% projected for 2026. US demand for kraft and specialty packaging papers increased 5% in 2025 to 3 million tonnes, with 1.6% growth expected in 2026. Unbleached packaging paper production for bag and sack grades rose 5.4% year-over-year in Q1 2026 to 520,000 tonnes. These numbers indicate that supply is expanding to meet growing demand, but at a measured pace that has not overbalanced the market.
On the supply side, capacity rationalization continues to reshape the market. Smurfit WestRock consolidated its European kraft and containerboard operations into high-efficiency mills in Spain, France, and Italy in early 2026. Palm Paper's PM7 in King's Lynn, UK, converted from newsprint to packaging grades, illustrating the industry-wide swing capacity shifting toward packaging. In Brazil, Klabin's Monte Alegre expansion added 150,000 tonnes of carbon-neutral kraft pulp capacity. However, these additions are roughly offset by closures and consolidations in higher-cost European and North American mills.
Sustainability trends are reshaping grade composition. Virgin kraft paper still dominates at approximately 72% of market share in 2025, according to Global Market Insights, but recycled grades are growing faster as brands pursue circular packaging targets. The recycled content share is projected to exceed 30% of total kraft paper production by 2026. For kraftliner specifically, recycled liner (testliner) is increasing its share where cost and recycling infrastructure are favorable, though virgin kraftliner remains essential for high-performance applications requiring strength, moisture resistance, and long fiber length.
EMR's forecast for the remainder of 2026 projects a global average kraft paper price range of $960-1,090 per tonne, with wood pulp costs, energy prices, and sustainable packaging demand as the key swing factors. The European premium relative to Asian markets will persist due to carbon costs and higher energy input prices. For procurement teams, the key risk is not a sharp price spike but a gradual upward drift as cost-push factors (pulp, energy, carbon) accumulate faster than capacity additions can offset them.
Kraft paper buyers face a market where steady upward creep — not sudden spikes — is the primary risk profile. With European prices at $1,360/t, Asia at $891/t, and global averages in the $960-1,090 range, the regional arbitrage opportunity is real but constrained by logistics. For heavy-volume sack kraft and kraftliner buyers, the tactical play should include three elements. First, use the regional price dispersion to your advantage: source within Europe for speed and reliability, but leverage Asian sourcing for multi-year contracts at a $400-500/t discount. Second, structure contracts with recycled content allowances — recycled grades are growing 1.5-2x faster than virgin and carry a structural cost advantage of 10-30% when OCC (old corrugated containers) supply is adequate. Third, monitor the growing multiwall sack demand in North America as a tightening signal for that segment — if US sack kraft demand continues at the 6-7% growth rate, domestic supply could become constrained by mid-2027, and multi-year contracts signed now may look favorable in retrospect. The circular economy shift is real and accelerating: buyers who build recycled fiber capacity into their supply partnerships will have a structural cost advantage over virgin-only sourcing strategies by 2028.
