EcoStretchRoll Spreader Rollers ensure stable Processes at Gröning
About Gröning Folien
W. Gröning GmbH & Co. KG, headquartered in Rheine-Mesum, Germany, is a fifth generation family-owned company and one of the established manufacturers of flexible packaging and technical films. Its range of services extends from film extrusion and flexographic printing to lamination and converting. With state-of-the-art production facilities and decades of expertise, Gröning develops customized film solutions for food, pet food, hygiene, and industrial packaging applications.
Wrinkle-Free Web Handling for Demanding Film Structures
The production of high-quality packaging films places stringent requirements on process reliability and web handling quality. Among other products, Gröning manufactures multi layer barrier films based on PE, EVOH, and PA, which are used worldwide in packaging applications for food, pet food, and other demanding markets.
To ensure a stable production process, the company relies on EcoStretchRoll spreader rollers. These are used at various stages of processing and provide reliable spreading of the film web. Particularly with multi-layer laminates and film structures with thicknesses of, for example, 60 μm, wrinkle-free web handling is essential to ensure consistently high product quality.
A key advantage of the EcoStretchRoll spreader rollers is their simple, low-maintenance operation. The rollers do not require an external drive and are powered solely by the moving web. This significantly reduces technical complexity and allows for particularly easy integration into existing production lines. At the same time, no adjustment or calibration of the roll is required, minimizing operator errors and reducing setup times.
In addition, EcoStretchRoll spreader rollers stand out for their universal applicability. Both narrow and wide webs can be processed reliably. The rollers perform consistently at different production speeds and with a wide variety of film materials. They are particularly effective in turn-bar systems, where they efficiently spread the film web and create ideal conditions for subsequent process steps.
Process stability and repeatability are especially important for packaging solutions intended for direct food contact. The films manufactured by Gröning meet demanding quality standards and are used in food packaging applications. Accordingly, EcoStretchRoll spreader rollers are also FDA-approved, making them ideally suited for use in sensitive production environments. Uniform web tension and reliable wrinkle prevention contribute significantly to consistently meeting these high quality requirements.
In addition to their technical performance, EcoStretchRoll spreader rollers also impressed with their ease of cleaning and high operational reliability. Their robust design ensures a long service life and supports cost-efficient production with minimal downtime.
Practical Benefits for the User
For Gröning, the high level of flexibility in day-to-day operations is particularly important. Different film structures, varying web widths, and changing product requirements can be processed without any adjustments. One specific advantage of the EcoStretchRoll is that a single spreader roller can handle a wide range of film widths and thicknesses. This eliminates the need for frequent roll changes or adjustments commonly associated with other spreading systems. At the same time, the uniform cross-web stretching improves downstream processing and reduces the risk of waste.
“With the EcoStretchRoll, we have sustainably improved web handling in our film production processes. We were particularly impressed by the easy integration without the need for an additional drive, as well as the high flexibility when processing different film widths and thicknesses,” reports David Wienkamp, Head of Extrusion at Gröning Folien.
Conclusion
By implementing EcoStretchRoll spreader rollers, Gröning has further optimized web handling in demanding film applications and significantly increased production reliability. The result is high-quality packaging films with consistently excellent quality for both national and international markets.
