Reifenhäuser at Chinaplas 2025: Recyclable packaging at competitive costs
At Chinaplas 2025, the Reifenhäuser Group will present its latest technological innovations for the efficient and sustainable production of plastic films. The extrusion specialists will showcase at Shenzhen World Exhibition & Convention Center from April 15 – 18 solutions that address the key challenges of today’s plastic industry: reducing resource consumption, increasing recyclability, and making production more autonomous and efficient. Meeting these demands requires advanced production technologies that Reifenhäuser already offers today.
A central focus at the show will be the use of Machine Direction Orientation (MDO) technologies for producing fully recyclable mono-material films with performance and cost-effectiveness equivalent to conventional multi-material structures.
Marcel Perrevort, CSO of the Reifenhäuser Group, explains: “In the flexible packaging sector, we are currently seeing a huge trend away from conventional and non-recyclable mixed material laminates towards fully recyclable mono-material composites, both for blown and cast films. Our state-of-the-art MDO stretching units enable enhanced mechanical properties for all-PE or all-PP films. Thus, PET films commonly used in material composites can be replaced. By downgauging, we also reduce production costs to a competitive level, making recyclable films a profitable choice.”
MDO for blown film lines
With the EVO Ultra Stretch MDO unit for Reifenhäuser’s blown film lines manufacturers produce all-PE mono films for applications such as high-barrier food pouches. Due to the stretch process film thicknesses of 18μm (with properties of a 25μm product) and less can be achieved, keeping production costs within the range of conventional films. With the patented integration of the MDO unit directly into the haul-off, the film is stretched in the ideal phase of the process – using the first heat – for maximum efficiency and film stability. Furthermore, the all-PE film achieves the required barrier effect with an EVOH content of less than five percent, fully meeting the criteria for recyclability. At the same time, Ultra Stretch enhances the performance of the EVOH barrier layer while reducing material usage, delivering cost and sustainability benefits.
