6.5 million Euro investment in Hosokawa Alpine MDO technology advances packaging innovation
We have successfully commissioned a state-of-the-art 5-layer blown film line with inline machine-direction orientation (MDO) from Hosokawa Alpine at our Pirk site in the Upper Palatinate. This EUR 6.5 million investment features twelve rollers instead of the usual ten, enhancing the homogeneity and physical properties of the stretched film and significantly improving film quality.

Introduction of new technology
Our new machine technology is utilized to produce EcoLamHighplus, part of our PE-based monopolymer EcoLam family. As Prof. Dr. Achim Grefenstein, our Head of Group Research and Development, explains, "Plastic packaging materials and films are essential in our modern world. The demand for more sustainable packaging solutions has increased continuously, driven by environmental protection efforts. Mono-materials or packaging laminates made from a single material are crucial for transitioning to a true circular economy, and Constantia Flexibles is committed to leading this trend."
Our approach to sustainability
At Constantia Flexibles, we pursue a 360-degree approach to offer recyclable solutions made of paper, aluminum, polypropylene, and polyethylene. The EUR 6.5 million investment in the MDO machine at our Constantia Pirk site was a logical step in expanding our range of services. The mono PE films produced are designed for recycling, reducing plastic consumption, and minimizing environmental impact compared to composite films.
Benefits of Hosokawa Alpine MDO technology
The Hosokawa Alpine MDO technology is a key component in producing high-performance mono-material composites made of polyethylene. This technology improves the optical and mechanical properties of the film, including transparency and editability, while enhancing the barrier effect to keep packaged products fresh and protected for longer. Additionally, MDO allows us to reduce the thickness and material use of PE films without compromising mechanical performance.
Collaboration and continuous improvement
Our collaboration with Hosokawa Alpine has continuously improved technical challenges regarding thickness profile and flatness, ensuring high film quality and process stability. The MDO PE film can be combined with a PE sealing film or metallized for increased barrier properties, retaining recyclability even when composed.
Future prospects
The market for MDO films and mono PE films has grown steadily and is expected to continue developing positively. As Prof. Dr. Grefenstein predicts, "The increasing demand for more sustainable packaging solutions and heightened consumer awareness of environmental issues will further accelerate the trend towards a circular economy. Our MDO technology significantly contributes to reducing plastic consumption and promoting recyclability, making it an attractive option for the packaging industry."
