- Facing the ever-increasing share of recycling material
- From twin- and single screw technology to Vacurema
- PET strapping tape technology from a single source
Reimotec Maschinen- und Anlagenbau GmbH is expanding its range of PET strapping tape lines by including the Vacurema system from recycling specialist Erema in its supply range.
Facing the ever-increasing share of recycling material
With more than 100 lines delivered for this application since 1977, Reimotec is considered as one of the leading suppliers of strapping tape production lines. In addition to providing its own technology for producing strapping tapes, the company also supplies the extrusion lines for producing the polymer melt. Today’s major challenge for this application is the ever-increasing share of recycling material in the resin, usually consisting of PET bottle flakes, in parallel to similarly increasing quality demands that are placed on the end product, namely the strapping tape.
From twin- and single screw technology to Vacurema
Previously, lines for PET strapping tape were equipped exclusively with single-screw extrusion systems until Reifenhäuser introduced its twin-screw technology (Reitruder) in 2001 and initiated an important step in the market towards the improved processing of PET bottle flakes. Since 2001, approximately three quarters of the strapping tape lines supplied worldwide by Reimotec have been equipped with this twin-screw technology, primarily due to the ease of applying this technology to the processing of PET bottle flakes.
A major advantage of the twin-screw, compared to the single-screw technology, is its better suitability for technically demanding recyclates. However, if the iV value of these raw materials is too low, the twin-screw extrusion reaches its limits. In order to meet the demands for processing raw materials even with critical iV values, Reimotec has now linked up with Erema. Erema offers the Vacurema system, consisting of modular, scalable components that can be adapted to meet the specific requirements of customers, depending on the quality of their PET bottle flakes.
PET strapping tape technology from a single source
Manufacturers of strapping tape are now able to adapt their lines better to the raw materials. In addition to the tried-and-tested technologies using single-screw and twin-screw extruders, they can now also obtain the Vacurema technology from a single source. At the same time, Erema customers can now use Reimotec’s proven technology for the production of strapping tapes.
