Packaging news hit a pivotal stretch in the final week of May 2026, with a fatal mill explosion threatening premium paperboard supply, Maine’s PFAS ban taking effect, and producers nationwide scrambling to meet the biggest packaging news EPR reporting deadline in U.S. history. Here is your full briefing covering the stories that matter most to brands, suppliers, and sustainability teams heading into June.
Materials & Sustainability
Interpack 2026 Closes as Largest Edition Ever
The world’s premier packaging trade fair wrapped May 13 in Düsseldorf, Germany, having drawn a record 2,804 exhibitors from 65 countries — the largest interpack in the show’s history. Innovation on the show floor centered on three themes: smart manufacturing with AI-driven automation, design-for-recycling materials, and readiness for the EU Packaging and Packaging Waste Regulation (PPWR). The European regulation dominated exhibitor conversations, with nearly every major machinery and materials company framing new launches around PPWR recyclability mandates. Explore how interpack’s automation breakthroughs connect to proven smart packaging technologies already reshaping brand engagement.
Greiner Packaging Debuts CUBO Mono-Material Container at Interpack
Among the standout interpack launches, Greiner Packaging unveiled CUBO — a square-format container engineered for better pallet efficiency and transit stability — alongside its Click In Sealing Lid, which collapses a three- or four-part closure into a two-part mono-material solution. Both innovations directly address the recyclability pressure of the PPWR while delivering tangible logistics savings. The Greiner launches reflect the industry’s accelerating pivot toward mono-material packaging strategies that simplify end-of-life sorting without compromising performance.
Maine’s PFAS Food Packaging Ban Takes Effect May 25
Maine became the first U.S. state to fully enforce a prohibition on intentionally added PFAS in plant-fiber food packaging, with the rule live as of May 25, 2026. The ban covers paperboard trays, molded pulp containers, paper wraps, pizza boxes, and fiber-based bowls sold in Maine — any product where PFAS were intentionally introduced above incidental presence. An exemption applies to brands with national sales below $1 billion. Brands above that threshold that have not completed reformulation of their plant-fiber foodservice items are now in violation in Maine.
California Flexible Film Recycling Races to Close a Massive Infrastructure Gap
Pressure from California’s SB 54 — which mandates 65% plastic recycling by 2032 — is forcing urgent capital investment in flexible film collection and processing. The state currently recycles less than 5% of flexible film, and projections from Delterra suggest 400,000 to 800,000 metric tons of post-consumer film will flow into the system as the law matures. The Recycling Partnership launched CalFFlex to provide capital funding for two MRFs and a secondary sorting facility, while the Flexible Film Recycling Alliance announced two California pilot programs launching this summer, with data expected in 2027.
EU Commission Publishes PPWR Implementation Guidance Ahead of August Deadline
With the European Packaging and Packaging Waste Regulation set to apply from August 12, 2026, the European Commission released detailed implementation guidance in May clarifying more than 30 provisions. Key clarifications: food contact packaging placed on the EU market before August 12 may remain in circulation until stocks are exhausted, but anything sold after that date must comply with PFAS limits immediately. Full recyclability requirements under Article 6(2)(a) phase in from January 1, 2030, or 24 months after related delegated acts enter into force, whichever is later.
Industry & Supply Chain
Nippon Dynawave Mill Explosion Kills Eight in Longview, Washington
A chemical storage tank implosion at Nippon Dynawave Packaging’s Longview, Washington mill on May 26 killed eight workers and injured several others — one of the most serious industrial disasters in recent U.S. packaging history. The facility, a subsidiary of Japan-based Nippon Paper, produces approximately 300,000 metric tons annually of premium paperboard for cartons and cups under the Structure-Pak and Structure-Serv brands. The U.S. Chemical Safety Board opened a root-cause investigation, and Nippon Paper said it is still assessing the impact on production and shipments, leaving downstream buyers of specialty paperboard in an uncertain position heading into June.
Containerboard Prices Set for a Third Wave of 2026 Increases
International Paper, Georgia-Pacific, Packaging Corporation of America, and Pratt Industries all announced containerboard price increases effective June 2026, making this the third upward pricing wave of the year. Containerboard had already risen a net $50 per ton year-to-date through April. Producers cite escalating input costs — chemicals, fuel, delivered wood, and energy — as justification, with several explicitly linking the cost pressure to the ongoing Iran conflict. Analysts say a fourth wave in late summer is possible if demand improves while input costs stay elevated.
Iran War and Tariffs Push Transpacific Shipping Up 30%
Two major geopolitical events are reshaping packaging supply chains in 2026. The ongoing Iran conflict has driven oil price spikes that flow directly into petroleum-based plastic costs, while transpacific shipping rates climbed nearly 30% between late February and early April. Steel and aluminum packaging faces 50% tariffs on fully metal items, and a key Chinese-parts tariff exemption for recycling equipment expired on May 31, adding uncertainty for MRF operators. According to Packaging Dive, most brands are absorbing costs or passing them to consumers rather than restructuring sourcing — a strategy that consultants warn is approaching its ceiling with price-sensitive shoppers.
New York EPR Bill Advances with Full-Cost-Coverage Model
New York’s packaging EPR bill (SB 1464) is pushing toward a June 10 legislature deadline after amendments narrowed its scope — removing a Toxics Packaging Task Force and delisting five chemical substances including halogenated flame retardants and polycarbonate. The bill’s 100% cost-coverage provision — where producers absorb all eligible program costs — sets it apart from the partial-cost models in Washington and Maryland and is likely to fuel intense industry lobbying before the session closes.
Oregon EPR Enforcement Remains Paused as July Trial Approaches
The National Association of Wholesaler-Distributors secured a federal injunction in February pausing enforcement of Oregon’s packaging EPR program, with a trial now scheduled for July 2026. The legal challenge centers on whether EPR requirements constitute an unconstitutional burden on interstate commerce. The Circular Action Alliance says it is pressing ahead with program implementation despite the injunction, but a ruling against the program could send ripple effects through the multi-state compliance infrastructure producers are building.
Regulations & Design
“Mega May” EPR Deadline: The Biggest Reporting Date in U.S. Packaging History
May 31 marked the most consequential reporting date yet in U.S. packaging EPR history. Annual Supply Reports were due in California, Colorado, and Oregon; Simplified Supply Reports were required in Minnesota, Maryland, and Washington; and California also required a Source Reduction Supply Report — all coordinated through the Circular Action Alliance. Compliance experts estimated only about 50% of obligated producers had registered by early April, and Oregon had already issued delinquency notices to brands that missed a March 31 deadline. Our detailed breakdown of California EPR requirements under SB 54 covers the foundational compliance framework, and last week’s packaging news roundup tracked the lead-up to this milestone.
Three California Packaging Labeling Bills Clear Key Legislative Votes
Three California packaging bills crossed a critical deadline this week. AB 2253 passed the Assembly 42–19 and moves to the Senate; it bans mass balance accounting for recycled-content claims and requires physical documentation that actual recycled material was used, expanding current rules beyond plastic food containers to all product categories. AB 1812 passed 64–1 and heads to the Senate; it prohibits the “compostable” label on any product made partially or entirely of plastic, taking effect in 2027. SB 1031 passed the Senate 29–9 and goes to the Assembly; it tightens distinctions between compostable and non-compostable products and mandates a health-impact study on degraded compostable plastics.
California Releases Illustrative SB 54 Fee Structure with $500M Annual Fund
CalRecycle released its illustrative fee structure under SB 54 on May 1, giving producers their first concrete look at cost exposure. The framework requires a $500 million annual contribution to a Plastic Pollution Mitigation Fund, with fees split 80% weight-based and 20% component-based. Proposed amendments would direct 60% of funds toward environmental justice communities and 40% toward ecosystem and health impacts. The illustrative fees are not final, but they allow procurement and sustainability teams to begin modeling cost scenarios before the rulemaking concludes.
Federal CIRCLE and PACK Acts Build Bipartisan Support in Committee
Two federal packaging bills are gaining traction. The CIRCLE Act would create an investment tax credit for recycling infrastructure and is backed by The Recycling Partnership, APR, and SWANA — referred to House Ways and Means. The PACK Act would establish an FTC framework requiring third-party certification for all recyclability and compostability claims, effectively preempting the rapidly multiplying state-level labeling bills — referred to House Energy and Commerce. Neither has a scheduled vote, but bipartisan co-sponsorship and the growing complexity of state-by-state compliance is increasing urgency for a federal standard.

Frequently Asked Questions
What is the “Mega May” EPR deadline and who does it affect?
The May 31, 2026 deadline required producers to file Annual Supply Reports with the Circular Action Alliance in California, Colorado, and Oregon, and Simplified Supply Reports in Minnesota, Maryland, and Washington. Any brand that sells packaged goods in those six states above minimum size thresholds is an obligated producer. Companies that missed the deadline face delinquency notices, public listing as noncompliant, and potential financial penalties.
What does Maine’s new PFAS packaging ban actually prohibit?
Effective May 25, 2026, Maine prohibits selling plant-fiber food packaging — including paperboard trays, molded pulp containers, paper wraps, and pizza boxes — that contains intentionally added PFAS above incidental levels. The rule applies to producers, suppliers, and distributors with national sales of $1 billion or more. Packaging already on the market before the effective date does not need to be immediately pulled from shelves.
How could the Nippon Dynawave mill explosion affect paperboard supply?
The Longview, Washington facility produces around 300,000 metric tons per year of premium paperboard for cartons and cups under the Structure-Pak and Structure-Serv brands. Until Nippon Paper discloses the extent of production disruption, buyers of specialty paperboard for beverage cartons and food cups should contact their suppliers to assess near-term availability and consider whether to accelerate orders or qualify alternative sources.
When does the EU Packaging and Packaging Waste Regulation take effect and what does it require?
The PPWR applies from August 12, 2026. Food contact packaging placed on the EU market before that date can remain in circulation until stocks are exhausted, but anything placed on the market after August 12 must comply with PFAS limits immediately. Recyclability requirements for all packaging phase in from January 1, 2030. The regulation also mandates reuse targets and extended producer responsibility requirements across all EU member states.
What is California’s AB 2253 and why does it matter for brands claiming recycled content?
AB 2253 passed the California Assembly 42–19 and now heads to the Senate. It bans mass balance and book-and-claim accounting for recycled-content claims, requiring instead that brands provide physical documentation proving actual recycled material was incorporated during production. It expands existing California rules beyond plastic food containers to all product categories. If enacted, brands will need to audit recycled-content verification processes across their entire portfolio sold in California.
