May in Review: Packaging’s Month of Mega-Mergers, AI Takeovers, and Fibre’s Finest Hour

The packaging industry entered May 2026 expecting the usual pre-summer lull. Instead, it got a month of billion-dollar deals, regulatory fireworks, and a quiet revolution in fibre-based technology. From Düsseldorf’s interpack halls to the boardrooms of Memphis and Zaragoza, May proved that this sector does not do boring.

The Consolidation Wave That Rewrote the Map

May’s M&A activity was staggering. Amcor delivered a masterclass in integration execution, reporting third-quarter adjusted earnings per share of US$0.96 on US$5.91 billion in revenue, while raising full-year synergy expectations from the Berry combination to US$270 million, exceeding the original US$260 million target. Total synergies now stand at US$650 million over three years, split across procurement (US$325 million), G&A (US$160 million), growth (US$60 million), and financial benefits (US$60 million).

International Paper made two strategic strikes. It acquired Delmarva Corrugated Packaging in Dover, Delaware, strengthening its East Coast presence , and separately announced a US$225 million corrugated plant in Mississippi with a staggering 2.2 billion can annual capacity in Northern India.

Saica Group dropped the month’s bombshell, acquiring German corrugated giant Thimm Group for an undisclosed sum. Thimm employs 2,500 people across Germany, Poland, Czech Republic, and Romania, with annual revenues of approximately €539 million (approximately US$582 million). Susana Alejandro, Saica’s President and CEO, noted that Thimm brings “strong regional capabilities in markets where Saica has not previously operated”. The combined entity now ranks among Europe’s largest family-owned packaging players.

Veritiv made two acquisitions of its own, Quick Pak in Tampa and Stickel Packaging Supply in New Jersey, deepening its Florida presence while strengthening penetration in underrepresented Northeast markets. Packaging Corporation of America continued integrating its US$1.8 billion Greif acquisition, reporting Q1 net income of US$171 million and EBITDA excluding special items of US$485.5 million, up from US$421.1 million a year earlier.Smurfit Westrock expanded its Latin American footprint, acquiring Cartomanabí in Ecuador with annual corrugated production capacity exceeding 50,000 tons.

Interpack 2026: Where Fibre Stole the Show

May’s interpack trade fair in Düsseldorf was not about incremental improvements, it was about category redefinition. Kiefel unveiled a breakthrough 100% cellulose-based barrier solution for fibre packaging, using a patented double-dip wet molding process that creates grease and oil barriers entirely from natural fibres without plastic coatings. The technology remained stable for weeks, even months, a game-changer for margarine tubs and takeaway food packaging.

PulPac unveiled new fibre-based caps developed with PA Consulting, designed to match the functional and consumer expectations of plastic alternatives. Early tests showed promising performance in thread engagement, sealing architectures, and tactile experience. A fibre-based cap that snaps, seals, and feels like plastic but recycles like paper is not a prototype, it is a production-ready solution.

Hubergroup relaunched its conventional offset ink portfolio with new resin technology delivering measurable improvements in misting reduction, a wider water window, and fewer make-ready sheets.

KHS Group announced an €11 million (approximately US$11.9 million) investment in a new Hamburg hall for its Plasmax barrier technology, coating PET bottles with a wafer-thin glass layer. The result is a PET bottle with the oxygen and CO₂ barrier of glass but the weight and shatter resistance of plastic, a combination that opens new categories for PET.

The Numbers That Mattered

Beyond the headlines, financial results revealed where value is being created. Amcor’s adjusted EBIT margins held at 15.1% for Q3, with the Global Rigid Packaging segment achieving approximately 13% margins despite absorbing a US$25 million storm impact.

PCA’s packaging segment EBITDA (excluding special items) hit US$482 million on US$2.2 billion sales, a 22% margin, up from 20.8% a year earlier. Nampak reported a 9% rise in normalised headline earnings while cutting debt 30% to R2.2 billion (approximately US$117 million), demonstrating that South Africa’s largest packaging group can expand margins while deleveraging.

Uflex delivered a 123% full-year profit increase on just 1.5% sales growth, proof that margin expansion, not top-line growth, is driving value in flexible packaging.

AI and Digital Transformation Arrived

PACK EXPO East 2026 in Philadelphia sent a clear signal: the industry’s next competitive edge is not faster machines, it is smarter, connected systems. The four trends dominating the floor were connected ecosystems, AI-powered predictive maintenance, real-time IoT visibility, and smart materials.

Esko unveiled its “Spec to Pack” approach, linking packaging specifications, assets, workflows, and production data across the packaging lifecycle in a single digital system, turning disconnected workflows into coordinated intelligence.

Regulation Tightened Its Grip

May saw governments translate sustainability promises into enforceable rules. The EU opened infringement procedures against 20 Member States for failing to transpose the green claims directive, with the 27 September application date looming. India’s FSSAI proposed a total plastic ban for gutka and pan masala packaging, mandating paper and cellulose only. Kenya’s manufacturers pushed back against a proposed 25% excise duty on kraft liner, warning export costs could rise 17%.

The PPWR faced a letter from 120 companies including Amcor, Aldi, and Ikea, urging the EU to keep implementation on schedule. The signatories warned that delays in secondary legislation would leave packaging converters uncertain about how to comply, even as 2030 deadlines approach.

The Takeaway

May 2026 will be remembered as the month when three trends converged. First, consolidation accelerated beyond organic growth, Amcor’s Berry integration, Saica’s Thimm acquisition, and PCA’s Greif integration all demonstrated that scale is no longer optional; it is a competitive prerequisite.

Second, fibre proved it can compete with plastic on performance. Kiefel’s 100% cellulose barrier and PulPac’s fibre-based caps are not prototypes, they are production-ready solutions that address the core technical barriers that have historically limited paper-based packaging.

Third, AI and digital connectivity moved from trade-show buzzwords to operational necessities. The gap between companies with connected, intelligent infrastructure and those without is widening every quarter.

The companies that will lead in the second half of 2026 are not the ones with the newest machines, they are the ones with the best-integrated operations, the most aggressive consolidation strategies, and the clearest path to fibre-based circularity. May proved that the packaging industry is not waiting for the future. It is building it.
