Hosokawa Alpine AG presents its range of services for the production of blown films at the K 2025 trade fair in Düsseldorf from 8 to 15 October 2025 under the motto ‘Blown film in perfection’. The presentation in Hall 16, Stand D06 focuses on the flexible 9-layer system from the Augsburg-based mechanical engineering company. Thanks to its unique adaptability, it gives customers the freedom to master future market requirements innovatively and confidently. With solutions for the production of sustainable full PE films and films made from PCR materials, Hosokawa Alpine is also addressing the major trade fair theme of ‘Shaping the circular economy’. At another stand, C34 in Hall 9, the company's recycling division will be showcasing its technologies, including those for recycling PCR plastics and films.

With over 25 years of experience in monoaxial stretching, we are the pioneers in MDO technology and have been regularly improving our process ever since. Today, customers benefit from the highest MDO film quality with outstanding processability and optimised flatness thanks to the vacuum technology introduced in 2021. The unique TRIO technology “Trim Reduction for Inline Orientation”, coupled with vacuum technology, ensures significant material savings during the edge trimming process.We now offer a quick-change system for stretching rollers to enable the processing of a wide variety of films. At the same time, we are presenting new cleaning solutions. This significantly increases the flexibility of MDO film production and further boosts productivity.

In keeping with the trade fair motto "Embracing digitalisation", we will be presenting practical solutions for system automation and digitalisation at K 2025 that enable customers to operate their blown film lines more efficiently, safely and economically. A digital start-up assistant supports fast and error-free start-up, modern monitoring solutions ensure full transparency during operation and predictive maintenance tools help to avoid unplanned downtimes. This gives customers more planning security, reduces downtimes and increases the overall performance of their production.

We have developed a solution for identifying and reproducing an optimum bubble geometry in blown film production. This is made possible by a permanently installed camera that photographs the bubble every 0.5 seconds. Once the optimum bubble geometry for a given application has been achieved, the settings are saved with the corresponding film recipe. "The desired bubble contour can then be automatically called up again any time once it has been saved for the first time," explains Bernd Bayer, Director R&D Blown Film Extrusion at Hosokawa Alpine.

At K 2025, we will present a newly developed granulate intake unit for extruders. The innovation impresses with its simple handling, harmonises perfectly with other Alpine system components, and reliably prevents dust deposits. As a result, users benefit from greater process reliability and consistently high product quality.
