Interpack & WEPACK 2026: Mono-Material + Digital Print Enable Recyclable Flexible Packaging

03 August 2026 · 8 min read

In the spring of 2026, the packaging world converged on two sides of the globe: WEPACK 2026 in Shenzhen (April) and interpack 2026 in Düsseldorf (May). Although separated by a month and thousands of kilometres, both events sent a unified, unmistakable signal: the deep integration of mono-material recyclable structures and digital printing is moving flexible packaging from a conceptual circular economy to an operational reality.

WEPACK 2026: cross-industry synergy and “paper–film fusion”

WEPACK 2026 delivered a remarkable performance: three days, 137,157 unique visitors, including 13,598 international attendees from more than 130 countries, alongside nearly 100 professional buying delegations. The numbers underscore China’s gravitational pull as a global packaging manufacturing hub.

But the most telling industry signal came from the inaugural “Innovative Flexible Packaging Special Zone – Paper & Film Sustainability”. For the first time, mono-material recyclable films, paper-based composites, and digital printing technologies were placed side by side as core pillars of the exhibition.

The strategic logic is clear: sustainable packaging is not a binary choice between paper and plastic, but a systemic challenge that demands cross-material collaboration. The zone spanned green materials, coating and converting, intelligent printing, and green factory & VOC management — a full-chain perspective. Concurrent forums, such as the Global Flexible Packaging Innovation & Sustainability Forum and ESG & Green Supply Chain Summit, linked regulatory pressure (like the EU PPWR) with technological execution, creating a coherent narrative from compliance to implementation.

On the hardware front, digital printing equipment dominated. Hanway, JHF, Shenzhen Wandong, Runtianzhi, and many others showcased high-speed single-pass inkjet systems for corrugated and flexible packaging; international names like Konica Minolta and Canon also presented flagship digital solutions. The takeaway: digital printing has moved far beyond “short-run prototyping” and entered the main stage of mass production.

WEPACK’s message: in the sustainability transition, isolated breakthroughs are no longer enough. Material suppliers, equipment makers, converters, and brand owners must form closed-loop collaboration. “Paper–film synergy” is not a slogan — it is the real direction of industrial restructuring.

interpack 2026: inkjet printing “takes over” the packaging industry

If WEPACK showcased China’s integration power, interpack 2026 presented the depth of global technological transformation. Official figures: 2,804 exhibitors from 65 countries, professional visitors from 161 countries, 75% from outside Germany and 28% from outside Europe — a record international footprint that confirms the global synchronisation of packaging change.

The forum agenda itself was a manifesto. The Spotlight stage covered daily themes: PPWR opportunities and risks, resource efficiency, smart packaging, AI and automation, circular economy, innovative materials — each day addressed a systemic challenge facing the industry.

But the most electrifying signal came from the inkjet printing sector. Multiple industry observers noted that inkjet was no longer a “nice to have” — it is now a dominant force reshaping the entire supply chain. SCREEN Europe demonstrated the Truepress PAC 520P, a digital inkjet press purpose-built for recyclable paper-based packaging, running at 80 m/min with water-based food-safe inks, eliminating plate-making and tooling. Crucially, SCREEN’s messaging tied directly to market reality: with PE prices surging due to geopolitical tensions (Strait of Hormuz) and PPWR compliance pressure, paper-based packaging is shifting from an “ESG story” to a commercial imperative.

This is a critical nuance: while mono-PE/PP recyclable structures are mature, raw material volatility and supply chain uncertainty are accelerating parallel investment in paper-based routes. The future is not “plastic vs. paper” — it is a pluralistic, multi-path landscape where both coexist.

Buyer delegations from Asia, the Middle East, and North America showed strong interest in corrugated digital printing solutions tailored to local e-commerce logistics, confirming that customisation driven by e-commerce is now a global phenomenon.

interpack’s message: the marriage of inkjet and sustainable packaging is not accidental — plate-less, on-demand ink supply inherently reduces material waste, resonating perfectly with PPWR compliance and carbon-footprint management. When “small batches, high variety” becomes the norm, digital printing is the key that makes flexible production economically viable.

Key takeaways from both events

• WEPACK 2026: Mono-material recyclable films + paper-based materials in parallel; digital inkjet printing in the spotlight; regulatory alignment through forums; strong buyer matching and cross-industry co-op.
• interpack 2026: Inkjet “taking over” packaging printing; paper-based packaging as a commercial hedge; PPWR as daily agenda; end-to-end displays from materials to software.
• Common denominator: Mono-material structures solve the “recyclability” problem at the base; digital printing adds the ability to personalise without added complexity. Together, they make every link — design, production, use, and recovery — traceable, manageable, and optimisable.

The convergence: how the recyclability loop becomes real

Bringing the two shows together, a clear logic emerges:

• Mono-material films (PE, PP, and increasingly paper-based alternatives) provide the structural foundation for recyclability, meeting the 90% single-material threshold required by CEFLEX and PPWR.
• Digital printing eliminates the need for protective varnishes or over-laminates in many cases, reducing material layers and simplifying recycling, while enabling variable data, traceability, and short-run economics.
• Together, they enable a “design-for-recycling” approach that does not sacrifice shelf appeal or barrier performance — a message reinforced by both WEPACK and interpack.

The loop is closing: brands can now design packaging that is both highly functional and fully recyclable, print it digitally with minimal waste, and have it recovered and recycled at end-of-life — all while meeting PPWR deadlines and consumer expectations.

What this means for converters, brands, and the supply chain

For decision-makers, two events have clarified the near-term roadmap:

1. Paper-based packaging is hitting a commercial tipping point. As SCREEN highlighted, resin price volatility and supply-chain risks are making paper not just an ESG choice but a financial hedge. The barrier performance, heat-sealability, and printability of paper-based structures are advancing fast — a natural extension of the “BOPET vs. BOPA” substrate logic you have previously explored.
2. PPWR compliance is no longer a distant deadline. From the forum agenda at interpack, European converters are treating 2030 as a daily reality. Export-oriented brands and converters need a clear action guide — from material selection to certification and reporting.
3. Digital printing ROI is becoming calculable. The sheer density of digital press exhibits at both events indicates that the technology is mature, but converters still need data-driven models to justify investment. Content that answers “how long until payback?” will be highly valuable.
4. China is increasingly part of the global sustainability conversation. With record international attendance at WEPACK and active Asian buyer delegations at interpack, cross-border collaboration is accelerating. This is a long-term narrative worth tracking.
