The global packaging industry entered 2026 navigating what many analysts describe as a structural turning point. While sustainability mandates and digital transformation have been shaping the sector for years, a new and unexpected catalyst ??the Strait of Hormuz disruption ??has dramatically accelerated the transition from plastic-based flexible packaging to digitally printed paper alternatives. The recently concluded interpack 2026 in D?sseldorf provided the clearest evidence yet that digital inkjet technology has moved from niche to necessity.

The Strait of Hormuz Disruption: A Supply Chain Wake-Up Call

The Strait of Hormuz, through which approximately 21% of global petroleum liquids flow, has experienced significant instability since early 2026. This disruption has sharply reduced petrochemical availability, directly impacting the global plastics supply chain. According to industry analysts, polyethylene spot prices in Europe have surged past levels seen during the 2022 Russia-Ukraine crisis, and a slow recovery trajectory is anticipated for shipping networks and production capacity well into the medium term.

For packaging converters ??companies that transform raw materials into finished packaging ??this volatility represents an existential challenge. Traditional flexible packaging relies heavily on plastic films derived from petrochemical feedstocks. With input costs spiraling and supply reliability uncertain, the business case for alternative substrates has never been stronger. Paper-based flexible packaging, once championed primarily for its environmental credentials, now offers a compelling economic advantage as well.

Industry reports indicate that converters who had been cautiously experimenting with fiber-based alternatives are now accelerating full-scale transitions. The structural premium now attached to secure chemical supply is expected to keep plastics prices elevated for the foreseeable future, making the shift to paper not just a sustainability choice but a margin-protection strategy.

interpack 2026: Digital Inkjet Takes Center Stage

Held May 7 to 13, 2026, at Messe D?sseldorf, interpack served as the global packaging industry’s definitive barometer. Across eight halls and thousands of exhibitors, one message resonated clearly: digital inkjet printing has matured into a commercially viable, high-speed solution for paper-based flexible packaging at scale.

SCREEN Truepress PAC 520P: A Landmark Demonstration

SCREEN, one of the technology leaders at the show, demonstrated its Truepress PAC 520P ??a water-based inkjet press engineered specifically for recyclable paper substrates. The press runs at 80 meters per minute using food-safe inks, requires zero plates or tooling, and is compatible with a range of sealing and barrier coatings. Live demonstrations drew consistent interest from converters reassessing their material strategies in light of the plastics crisis.

Juan Cano, Business Development Director for Flexible Packaging Printing at SCREEN Europe, presented at the interpack SPOTLIGHT Forum, drawing on real-world evidence from installations at Sacchital in Italy and Chiyoda Gravure Corporation in Japan ??both now printing for major specialty food brands. These landmark installations confirm that digital inkjet can meet the color accuracy and consistency demanded by global brand owners while enabling short and medium runs that conventional gravure or flexo simply cannot support economically.

Koenig and Bauer: Smart. Connected. Secure. Ecosystem

Koenig and Bauer, exhibiting in Hall 8B, presented its comprehensive digital ecosystem under the keynote theme “Smart. Connected. Secure.” Their RotaJET platform demonstrated high-volume inkjet printing at speeds for print widths up to 1,600 mm, combined with sustainable energy concepts and compatibility with eco-friendly ink systems. The company’s “IMPACT” strategy, introduced in March 2026, underscores how major OEMs are positioning themselves not just as machine suppliers but as digital transformation partners for the entire packaging value chain.

PPWR Compliance: The Regulatory Accelerator

Beyond the raw material crisis, the European Union’s Packaging and Packaging Waste Regulation (PPWR) is tightening requirements around recyclability and recycled content. The regulation mandates that packaging be designed for circularity, with escalating compliance deadlines through 2030. Paper-based solutions ??particularly those printed with water-based, food-safe inks ??align naturally with PPWR objectives, avoiding the complex recycling challenges associated with multi-layer plastic laminates.

Converters who adopt digital inkjet for paper packaging are de facto positioning themselves ahead of regulatory enforcement timelines. The combination of Strait of Hormuz-driven plastic cost inflation and PPWR compliance pressure has created what industry observers call a “dual forcing function” ??compressing investment cycles that might otherwise have spanned five to seven years into much shorter timeframes.

Market Data: The Numbers Behind the Shift

The paper bags and flexible paper packaging market, valued at approximately USD 6.8 billion in 2025, is projected to reach USD 10.9 billion by 2036, growing at a compound annual growth rate (CAGR) of 4.4% according to Future Market Insights. India leads regional growth at 5.5% CAGR, followed by China at 5.3%. Brown kraft dominates the material segment with a 58% market share, prized for its strength characteristics and cost efficiency.

Meanwhile, the broader packaging machinery market ??estimated at USD 53.2 billion in 2026 ??is projected to reach nearly USD 90 billion by 2035, driven largely by the converter upgrade cycle toward digital and fiber-compatible equipment. Direct sales channels account for 75% of distribution, reflecting the consultative, relationship-driven nature of B2B machinery procurement in this space.

What This Means for Packaging Machinery Buyers

For B2B buyers evaluating machinery investments in the second half of 2026, three strategic takeaways emerge from the interpack conversations and market data:

1. Substrate flexibility is non-negotiable. Machines capable of handling both traditional materials and next-generation paper-based substrates deliver the best risk-adjusted return on investment. Converters locked into plastic-only production lines face growing margin pressure as polyethylene costs remain elevated.

2. Digital capability is becoming table stakes. The ability to offer short runs, variable data printing, and rapid changeovers differentiates suppliers in an increasingly fragmented market. Digital inkjet makes these capabilities economically viable where conventional methods cannot compete.

3. Total Cost of Ownership must account for regulatory risk. PPWR compliance costs, plastic price volatility, and shifting brand-owner sustainability requirements mean the cheapest machine at purchase is rarely the cheapest over a five-year operating horizon.
