On April 16, 2026, International Paper (IP): one of the world’s largest pulp, paper, and packaging companies: announced a definitive agreement to acquire NORPAC (North Pacific Paper Company) from private equity firm One Rock Capital Partners for $360 million. The Longview, Washington mill will add approximately one million short tons of annual containerboard capacity to IP’s existing North American network.
The deal is yet another signal that North American containerboard production is consolidating around a small number of dominant players, with direct implications for paper packaging manufacturers and buyers worldwide.
What Is NORPAC?
North Pacific Paper Company (NORPAC) operates in Longview, Washington, running three paper machines with a combined annual capacity of approximately one million short tons of containerboard and related grades. The facility employs roughly 500 people and has operated for approximately 50 years.
NORPAC was originally founded in 1976 as a joint venture between Nippon Paper Industries (Japan) and Weyerhaeuser (USA), reflecting the early integration between North American forestry resources and Japanese paper manufacturing expertise. One Rock Capital Partners acquired the operation in 2016 and, starting in 2021, executed a strategic shift from publication papers (newsprint) toward lightweight recycled containerboard: the very product category now driving demand across e-commerce and fast-moving consumer goods packaging.
The Strategic Logic Behind the Deal
This acquisition fits directly into CEO Andy Silvernail’s ongoing transformation strategy at IP. The company has been simultaneously closing underperforming facilities and making targeted capacity investments: including the completion of the DS Smith merger (Europe) and a $225 million investment in a Mississippi facility: while steadily reshaping itself into a focused global packaging company.
NORPAC fills a critical geographic gap. Tom Hamic, IP’s Executive Vice President and President of Packaging Solutions North America, explained:
“This acquisition is a strong strategic fit for our business. NORPAC’s attractive customer base, location and operational capabilities strengthen our ability to serve customers in the growing West Coast region.”
Three strategic pillars stand out:
- West Coast footprint: proximity to major e-commerce logistics hubs (Amazon, Walmart distribution centers) concentrated in the Pacific Northwest and California
- Recycled lightweight containerboard: NORPAC’s converted capacity aligns with accelerating demand for sustainable, low-weight packaging solutions
- Operational synergies: IP already operates multiple production and recycling sites in Washington and Oregon, creating cost and logistics optimization opportunities
The transaction is expected to close in Q3 2026, subject to regulatory approval.
North American Containerboard Market Context
The deal arrives amid a challenging macro environment for containerboard. Q1 2026 saw North American containerboard production decline at one of the steepest rates in recent years, reflecting weaker-than-expected demand recovery and ongoing inventory destocking.
In this environment, scale and operational flexibility matter more than ever. By absorbing NORPAC’s one million tons of annual capacity, IP further strengthens its ability to optimize system-wide production, reduce per-unit costs, and offer customers a more integrated West-Coast-to-East-Coast service proposition. Smaller regional producers face growing competitive pressure as a result.
Implications for Korea’s Paper Packaging Industry
While this transaction is North American in scope, Korean paper packaging manufacturers, corrugated board producers, and raw material buyers have reason to pay attention to three developing trends.
1. Accelerating Global Consolidation: Pricing Power Implications
IP’s back-to-back acquisitions of DS Smith (Europe) and NORPAC (North America West) are transforming the company into a genuinely global integrated packaging platform. When dominant buyers or suppliers consolidate at this scale, negotiating leverage shifts: input costs for mid-size manufacturers tend to rise, and supply flexibility narrows.
Korean packaging companies that import North American or globally-priced containerboard grades should monitor whether this consolidation translates into pricing pressure in 2026–2027.
2. The Recycled Lightweight Containerboard Shift Is Real
NORPAC’s transition from newsprint to recycled lightweight containerboard: completed under One Rock’s ownership: is a microcosm of a broader global trend. Major global retailers and brands are actively specifying recycled-content, lightweight packaging in procurement contracts. This requirement is already codified in the EU PPWR framework (effective August 2026) and is spreading to Asia-Pacific supply chains.
Korean corrugated and paper packaging exporters should proactively benchmark their recycled content ratios and basis-weight targets against evolving global buyer requirements.
3. Asia’s Roots in NORPAC: A Reminder of Regional Interconnection
NORPAC’s origins as a Nippon Paper–Weyerhaeuser joint venture are a reminder that the paper industry’s North American and Asian supply chains have long been intertwined. That connection: now absorbed into IP’s global structure: illustrates how M&A activity in any major region can ripple through Asian raw material supply relationships. Korean procurement teams monitoring global paper industry M&A should track how IP integrates NORPAC into its broader system.
Frequently Asked Questions
Q: How much is International Paper paying for NORPAC?
International Paper agreed to pay $360 million to acquire NORPAC from private equity firm One Rock Capital Partners. The deal was announced on April 16, 2026, and is expected to close by Q3 2026, subject to regulatory approval.
Q: Where is NORPAC located, and how much does it produce?
NORPAC operates in Longview, Washington, with three paper machines producing approximately one million short tons per year of containerboard and related grades. The facility employs around 500 people and has a 50-year operating history, having originated as a Nippon Paper Industries–Weyerhaeuser joint venture in 1976.
Q: Why does this deal matter for the Korean packaging industry?
The direct short-term impact on Korean manufacturers is limited. However, three trends deserve monitoring: (1) North American containerboard supply consolidation may affect imported raw material pricing; (2) the deal reinforces the global shift toward recycled, lightweight containerboard that Korean exporters will need to meet; and (3) it illustrates how global M&A reshapes the supply chains that Asian paper markets depend on.
