Transforming Plastics at K Preview 2025: Pioneering Circular Design and Smart Automation for a Sustainable Future
At a time when plastic is coming under increasing scrutiny around the world—fueled by increasing awareness, consumer demand, and rising evidence of environmental damage—Reifenhäuser took a bold and timely move at K‑Preview 2025. Rather than simply demoing a slate of machines, the leader in extrusion technology presented a visionary case: converting plastics to a circular, high-performance, efficient material. Reifenhäuser’s presentation went beyond typical trade-show fare, providing a template for environmentally conscious yet commercially real packaging production.
Leading the spotlight was the revolutionary Machine Direction Orientation (MDO) technology, epitomized by the EVO Ultra Stretch module integrated directly into the haul-off section of blown film lines. This positioning allows the film to be stretched immediately from the initial heating, improving process stability and enabling the production of ultra-thin polyethylene (PE) films as thin as 18 µm, yet matching or even exceeding the performance of traditional 25 µm variants.
Marcel Perrevort, CSO of the Reifenhäuser Group, explains: “We entered the cast MDO market at an early stage, which means that, in addition to the hardware, we have a firm knowledge of the process. Together with partners, we develop high-performance end products such as Cast All-PE stand-up pouches. As a line manufacturer, we always pursue one goal: to develop2/4 technology for recyclable films that are both functional and economical to produce. We will be showcasing the successful results at K 2025.”
The implications are significant: a 25 percent reduction in raw material use, directly translating into lower carbon emissions and raw material costs. These films also maintain high mechanical robustness—with moduli of elasticity exceeding 1,400 MPa in machine direction and 1,100 MPa in transverse direction—and optical clarity with haze values below 5%, outperforming conventional benchmarks of 6–7%.
Crucially, the EVO Ultra Stretch maintains EVOH barrier content under 5%, ensuring compatibility with mono-material PE recycling standards. This means that while delivering high barrier functionality necessary for food and medical packaging applications, the entire film structure remains fully recyclable—a rare combination of performance and sustainability. Equally compelling were the real-world demonstrations: the 18 µm films were printed at speeds of up to 500 m/min on Bobst presses, with exceptional register accuracy—even in BOBST’s demanding oneECG gravure process at over 300 m/min.
Backing this innovation is a strategic collaboration with LG Chem, formalized through an MoU on 28 November 2024. The partnership leverages LG Chem’s expertise in polymer compounding with Reifenhäuser’s extrusion know-how, aiming to produce cost-competitive, high-quality MDO-PE films for recyclable packaging. The recent rollout of the world’s first 18 µm MDO-PE film is now scaling toward mainstream adoption. As Bernd Reifenhäuser, CEO, remarked, the alliance aligns raw materials, extrusion precision, and production reliability—enabling recyclable mono-material films to transition from concept to mass production. Dr. Lee Choong Hoon of LG Chem praised the partnership’s establishment of “unprecedented records in downgauging”—while confirming that further material reduction remains under active development.
The collaboration’s commercial aim is clear: make recyclable packaging not just environmental idealism, but an economically viable, mainstream solution. That goal is underscored by the common industry benchmark: replacing a 12 µm PET layer with a 16–17 µm MDO-PE, offering parity while ensuring recyclability. With the EVO Ultra Stretch already achieving 18 µm reliably, the MoU targets cost-efficient packaging that aligns with consumer expectations and regulatory demands.
Reifenhäuser didn’t stop at blown film innovation. The event also unveiled the MIDEX 11‑2500 cast film line, now equipped with integrated MDO. Designed for a variety of films—CPP, CPE, barrier variants, hygiene materials—this platform supports material downgauging while preserving performance. By enabling thinner, mono-material films that match multilayer laminates in strength and barrier function, the MIDEX line contributes to reducing material consumption and waste—a critical step toward circularity.
Automation, too, formed a core theme at K‑Preview, centered around PAM (Precise, Autonomous, Mechatronic). This intelligent system replaces traditional manual bolt adjustments in coextrusion adapters and dies with digitally controlled actuators. The result is consistent film quality, dramatically reduced energy use—up to 99% less than conventional thermal-bolt setups—and reduced operator skill requirements, bolstering safety, uptime, and productivity. PAM exemplifies Industry 4.0 principles: smart, efficient, and adaptive manufacturing that supports sustainability goals through precise control and energy optimization.
Thermal management received special attention through Kdesign, Reifenhäuser’s cooling technology arm. The highlight was the KARAT cooling ring, capable of boosting output by up to 50% on mid-range operations and improving performance by 25% compared to top-tier competitors. This new standard in cooling efficiency helps meet the growing pressure for speed and quality without excessive energy or material usage.
In hot or humid production environments, the CENTRO‑Freeze secondary cooling system delivers another leap in efficiency. Installed just before the film lay-flat stage, CENTRO‑Freeze reduces film temperature by up to 12 °C, effectively preventing blocking and eliminating reliance on anti-blocking additives. That means fewer materials in the mix, more reliable production under heat stress, and a payback within a couple of hot summer cycles. Users can digitize monitoring with inline temperature sensors and rely on automatic format adjustment during bubble diameter changes—delivering both energy savings and operational convenience.
To support global deployment, Reifenhäuser announced the opening of a new Service Hub in the UAE, complemented by increased support networks across the MEA region. This facility offers local installation, commissioning, spare parts, and expert training—critical for maintaining service uptime and supporting regional market growth. By placing capabilities closer to clients, Reifenhäuser enhances responsiveness and helps partner companies integrate sustainable technologies smoothly.
K-Preview 2025 set a powerful tone ahead of the full K 2025 expo in October, framing Reifenhäuser as not just an equipment vendor but a strategic partner for sustainable packaging transformation. The cohesive display—from MDO and cast film to automation, cooling, and global service—underscores a comprehensive commitment to enabling circular plastics. The timing is perfect. With consumer demand for recyclable products and legislative initiatives such as the EU’s packaging waste directive pushing for change, film downgauging and mono-material packaging are now short-term imperatives. The potential to lower material usage by 25% with PET-level performance provides manufacturers with much better margins and environmental credentials.
On the broader industry front, Drupa 2024 already showcased high-barrier recyclable films; now, K-Preview reinforced the convergence of recycling and extrusion at trade events. Meanwhile, competitors like Erema are focusing on recycling systems, signaling a unified push across value chains toward circular solutions.
Looking ahead, Reifenhäuser and LG Chem are continuing joint R&D toward films thinner than 18 µm and free of PFAS—all while refining formulations, ensuring extrusion stability, and meeting performance targets. Applications are poised to expand beyond flexible packaging into medical, hygiene, and high-barrier food applications—all benefiting from mono-material simplicity and full recyclability.
As production ecosystems embraced by K‑Preview demonstrate, the future of plastics lies in digital, energy-optimized, recyclable manufacturing. Technologies like EVO Ultra Stretch, MIDEX, PAM, KARAT, and CENTRO‑Freeze are not stand-alone innovations—they form an integrated infrastructure enabling digital continuity, resource efficiency, downgauging, and environmental responsibility.
Reifenhäuser’s clear message: sustainability and profitability are neither optional nor conflicting—they’re inseparable. By delivering technical innovation in film production, barrier technology, automation, cooling, and service networks, the company is building a pathway for global packaging manufacturers to adopt circular, high-performance, cost-effective solutions.
That vision has immediate resonance. With regulatory deadlines nearing and consumers demanding greener packaging, the time for recyclable mono-material film is now. Reifenhäuser’s approach may well redefine industry expectations—and manufacturers who adopt these systems early could gain a competitive head start in cost, compliance, and brand appeal.
In sum, K‑Preview 2025 was more than an exhibition—it was a manifesto for the future of plastics. By combining revolutionary machine design, strategic raw material partnership with LG Chem, digital controls, thermal innovation, and global service expansion, Reifenhäuser has delivered a credible, scalable, and profitable path to circularity. Their message is clear: the plastics economy of tomorrow will be circular, high-performing, and meticulously engineered, and Reifenhäuser is paving the road.
