The line manufacturer Reifenhäuser Blown Film has developed a technology that makes blown film producers independent of highly fluctuating recyclate qualities and ensures a stable production process - even when processing low-quality input material: EVO Fusion upgrades recyclate qualities.
With EVO Fusion, blown film producers can also process previously unusable, lowest-quality recyclates into high-performance blown films for simple end-uses, such as bin liners or mailing bags. Until now, such low-value recyclates could only be used for simple and thick-walled injection moulded products. In addition, EVO Fusion enables producers to produce higher-quality film from recyclates that could also be processed in the past.
Eugen Friedel, Director Sales at Reifenhäuser Blown Film, explains: "In order to drive the circular economy, the recyclate ratio in blown film products must increase and classic downcycling must be limited. With EVO Fusion, we offer a unique process with which customers can process even low recyclate qualities easily and economically into high-performance products and increase the recyclate content. In this way, processors open up new fields of application for recycled products."
The EVO Ultra Fusion process relies on direct extrusion, which dispenses with the energy- and cost-intensive regranulation of the starting material. This means that fluff (film shreds) and all kinds of production waste and PCR material can also be processed directly.
This is made possible by the 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, removing unwanted components in the recyclate.
For processing better quality regranulates, Reifenhäuser recommends the EVO Ultra single-screw extruder. Thanks to optimised barrier as well as shear and mixing parts, this extruder processes recycled material as reliably and naturally as other raw materials - the ideal prerequisite for success in the growing market for products with a high recycled content.
