Kraft paper prices firming on regulatory tailwinds and e-commerce demand

Price action: steady firming across regions

Global kraft paper prices have been stable to modestly firm through the first half of 2026. The global blended average sat at $0.997/kg in Q1 2026, essentially flat compared to the $0.975-0.980/kg range that held through most of 2025, according to Expert Market Research. The consistency across quarters suggests producer cost floors — elevated wood pulp and energy costs — are setting the floor, while demand from packaging and e-commerce provides the ceiling.

Regionally, the US has been the standout. US kraft paper reached $1.27/kg in Q1 2026, up 2.4% from $1.24/kg in Q4 2025, the highest among Western markets. Europe followed at $1.36/kg, up 1.1% quarter-over-quarter, supported by consistent demand from retail and packaging industries despite generally cautious procurement. France, the highest-priced European market, reached $1.453/kg in Q4 2025, broadly flat from Q3 as packaging demand softened and buyer destocking weighed.

India remains the lowest-cost producer globally at $0.44/kg, leveraging recycled fiber, bagasse, and agro-residue furnish that structurally undercuts the wood pulp-based costs of Western mills. This creates a bifurcated market: domestic-focused Asian producers compete on cost, while export-oriented Western mills compete on quality, strength, and regulatory compliance.

Regulatory demand: the California plastic bag ban and beyond

California's statewide ban on single-use plastic bags took effect in January 2026, mandating paper or reusable options in retail environments. This is the single largest regulatory shift for the kraft paper market in 2026. California accounts for roughly 12% of the US population and a disproportionate share of retail volume. The mandate directly lifts demand for kraft paper bags, sack kraft, and liner grades used in retail packaging.

The regulatory wave extends beyond California. Europe is witnessing a notable shift toward paper-based grocery and retail bags, driven by the EU Single-Use Plastics Directive and national implementation measures. In January 2026, Smurfit WestRock began consolidating its European kraft and containerboard operations into high-efficiency mills in Spain, France and Italy, positioning for this demand growth.

Globally, the kraft paper market is projected to grow from approximately $71 billion in 2026 to $128.3 billion by 2035, a CAGR of 6.8%, according to Global Market Insights. The bags and sacks segment alone is expected to reach $65 billion by 2035 at a CAGR of 7.6%. The regulatory push for plastic replacement is the primary driver — bag bans, food packaging restrictions, and e-commerce packaging mandates are accelerating adoption across all regions.

E-commerce and packaging: the structural growth engine

Packaging papers — including kraft liners, sack kraft, and specialty wrapping grades — represent the fastest-growing demand segment within the broader paper and pulp industry. This is driven by the structural shift in consumer purchasing toward online retail, food delivery, and sustainable packaging alternatives to plastic.

Corrugated medium made from kraft is expected to exceed $15.6 billion in market applications in 2026, according to industry estimates. The math is straightforward: every e-commerce shipment requires a corrugated box or paper mailer, and the shift from plastic to paper packaging amplifies the demand growth beyond what e-commerce alone would produce.

US kraft and specialty packaging papers grew 5% in 2025 to roughly 3 million tonnes, with an additional 1.6% growth expected in 2026, according to Fastmarkets. US multiwall paper — used for cement, chemicals, and heavy industry sacks — registered shipments of 389,000 tonnes in 2025, a 13.1% annual increase, with 6.7% further growth projected for 2026.

Capacity and supply dynamics: consolidation and expansion

The supply side is undergoing two trends at once: consolidation in developed markets and expansion in emerging regions. Smurfit WestRock (formed from the 2024 merger) is consolidating European kraft and containerboard operations into high-efficiency mills, focusing on scale and cost optimization in sack kraft and containerboard grades. Mondi expanded kraft paper capability by ramping its Steti mill in the Czech Republic with new machines supporting higher packaging-grade volumes.

In Latin America, Klabin completed its Monte Alegre expansion in December 2025, adding 150,000 tonnes of carbon-neutral kraft pulp capacity. Its earlier Puma II project (2024) increased containerboard and kraft paper output for export and domestic Latin American markets. Holmen Board & Paper launched a next-generation lightweight kraftliner in September 2025 focusing on material reduction without compromising strength.

These expansions are not happening in isolation. The Navigator Company showcased its gKRAFT sustainable packaging products at the Packaging Innovations Fair in January 2026, signaling continued investment into fiber-based alternatives to plastic. The result is a market where capacity is gradually expanding, but the growth in demand — particularly from plastic substitution — is absorbing the additional tonnage without creating oversupply.

Analyst views: bullish on plastic substitution, cautious on macro risk

Bull case

The bull case for kraft paper is driven by the structural and largely irreversible shift away from single-use plastics. California's ban is expected to be followed by other states, and the EU regulatory framework is tightening further. E-commerce continues to grow at 8-12% annually globally. Under this scenario, the 6.8% CAGR through 2035 is achievable, and kraft paper prices could trend gradually higher as demand outpaces capacity additions.

Bear case

The bear case focuses on downside macro risks. A slowing economy would reduce industrial sack demand (cement, chemicals, construction aggregates). The US multiwall segment, which posted 13.1% growth in 2025, could slow sharply in a recession. New capacity from Smurfit WestRock, Klabin, and Mondi could temporarily outpace demand growth, pressuring prices. The 2025 experience of global blended prices easing from $0.98/kg to $0.975/kg demonstrates how incremental oversupply can cap upside even in favorable demand conditions.

Base case

The base case is steady growth with stable pricing above 2025 levels. Regulatory tailwinds provide a demand floor. Elevated pulp and energy costs set a producer cost floor. E-commerce and industrial packaging demand provide the volume growth. Capacity additions are largely absorbed by demand growth. Kraft paper prices are expected to hold near current levels through H2 2026, with modest 1-2% increases possible in Q4 as seasonal packaging demand peaks.
