NE Engineering eliminates end-of-line bottlenecks for Adara Pakkaus with new 2UpSide palletiser

The classic converting trap avoided

There is a recurring operational trap in the corrugated packaging industry that I have witnessed time and time again over the decades: a plant invests heavily in a state-of-the-art, ultra-high-speed converting line, only to realize that their existing end-of-line infrastructure cannot handle the output. The result is a multi-million-euro machine forced to run at a fraction of its mechanical capacity. Adara Pakkaus, the prominent Finnish corrugated manufacturer, has smartly bypassed this pitfall at its Valkeakoski facility by pairing its latest acquisition with targeted robotic automation.

NE Engineering (NEE) has officially confirmed the successful installation and commissioning of its new 2UpSide palletising robot at the Adara Pakkaus plant. This strategic deployment ensures that the facility's newly installed casemaker can operate at its absolute maximum speed without triggering a backlog of bundles on the factory floor.

Handling the Dual Slotter multiplier effect

The context of this installation is what makes it technically significant. The NEE 2UpSide palletiser is positioned directly downstream from a brand-new MHI EVOL 100 flexo folder gluer. Ordered in 2025 and commissioned this summer of 2026, the EVOL line was supplied complete with an MPF-M pre-feeder, an MBS system, and crucially, a Dual Slotter (DSL). For those familiar with high-volume casemaking, the inclusion of a Dual Slotter changes the entire mathematical equation of the production run.

By allowing the machine to process two boxes per single corrugated sheet, the Dual Slotter effectively doubles the bundle output rate when running smaller formats. This creates a relentless, high-velocity stream of bundles exiting the folder gluer. Traditional palletising systems often choke under this volume, struggling to square, stack, and discharge the pallets fast enough. The 2UpSide palletiser was specifically engineered by NEE to absorb this exact type of punishment. It manages the complex bundle configurations seamlessly, maintaining perfect stack integrity and preventing the dreaded bottleneck that forces operators to dial down the EVOL's cruising speed.

Strategic growth in the Nordic market

This technical upgrade aligns perfectly with Adara Pakkaus's broader corporate strategy. Following a strong financial performance in 2025—where the company reported a turnover of EUR 52 million and an annual production of 70 million square meters—Adara has been refining its operational footprint. The late 2024 acquisition of ER-Pahvityö Oy allowed Adara to offload fast-cycle, small-series production to its new subsidiary. Consequently, the main Valkeakoski plant has been optimized for medium and high-volume runs.

In a high-volume environment, particularly in the Nordic region where labor costs are premium and operational efficiency is paramount, automation is not a luxury; it is the baseline for profitability. By integrating the MHI EVOL with NE Engineering's robotic palletising, Adara has created a highly synchronized, continuous-flow manufacturing cell that maximizes the yield of every working hour.

The future of bundle handling

The successful commissioning of the 2UpSide unit also highlights a broader industry shift. We are moving away from isolated machine purchases toward holistic line integration. The communication between the casemaker's delivery end and the robotic palletiser must be instantaneous, ensuring that any micro-stoppages are managed without cascading into a full line halt. NE Engineering's ability to match the aggressive output of the EVOL 100 proves that modern robotics can finally keep pace with the fastest mechanical converting technologies on the market.

Seeing a high-speed line run at full throttle without the end-of-line operators breaking a sweat is the true benchmark of a successful installation, and NE Engineering has delivered exactly that for Adara. As converting speeds continue to push the physical limits of corrugated board, will we soon see AI-driven predictive palletising become the standard for all new flexo folder gluers?
