Suppliers of blown film extrusion lines demon-
strated the possibilities of incorporating recycled material in new PE production during K2022. Italian manufacturer Macchi displayed an R-POD Flex line, the latest in its polyolefin film lines, which has been specifically designed for very high productiv- ity and for the use of recycled materials. The company says: “This new technology allows [us] to meet the growing market demand of highly flexible extrusion lines, capable of extruding recycled materials up to 1,200 kg/h at 2,500 mm net width.” The new design and mix of extrusion screws in R-POD Flex allows greater flexibility in the process- ing of different materials and, at the same time, a greater extrusion capacity in 65/80/120/80/65 configuration. It also features a new TE556 Coex- flex series extrusion head, specifically designed to manage both polyolefin and regenerated film formulations on the same line, says Macchi. Reifenhäuser’s blown film business showed the
new EVO Ultra Fusion process, which can handle strongly fluctuating recyclate quality and ensures a stable production process. The system relies on direct extrusion and avoids energy-intensive and costly regranulation of the starting material. Fluff (foil snippets) and all types of production waste and PCR material can also be processed directly. Reifenhäuser says this is made possible by its twin-screw technology, which homogenises the melt better and thus ensures a stable process. In addition, processors can degas the system very easily and effectively, thereby removing unwanted components in the recyclate. At K2022, Reifenhäuser also highlighted the
help that processors of recyclate-containing materials can receive from its Reiloy screws and barrels business. It says: “Whether film manufac- turer, injection moulder or plant manufacturer: The processing of recyclate poses challenges for everyone, because recyclate is complex as a raw material and a stress test for the plasticising unit.
Highly wear-resistant cylinders and screws from Reifenhäuser Reiloy enable a long service life of the unit and high quality of the products.” Reifenhäuser Reiloy’s screws and barrels are
made from special iron-based alloys and nickel- based alloys, which are suitable for the raw material being processed, and ensure greater resistance to wear. It says the decisive factor is the composition of the alloys, because wear protection not only depends on the hardness of the layer.
