Erema to stage symposium on PET Strapping


   High-duty PET strapping band from PET bottle flake, produced economically with the new plant concept from Erema and Techno Plastic: a Vacurema Basic 1308 TE-VSV and directly coupled stretching plant Tight Strap 300 with up to 130 m/min drawing speed and 300 kg/h production capacity.Erema, the Austrian manufacturer of plastic recycling systems, and their technology partner Techno Plastic s.r.l., Castelfranco Emilia (Modena), Italy (www.technoplastic.it), are to hold a special symposium on PET Strapping, the inline processing of PET bottle flake to make strapping and monofilaments, on the 27th and 28th of October this year. This Open House event at Erema's Ansfelden headquarters will feature the demonstration of a system optimised especially for the manufacture of PET strapping, consisting of an Erema Vacurema Basic 1308 TE-VSV extrusion system and a Techno Plastic Tight Strap 300 stretching plant connected directly to it. The throughput of the plant is up to 300 kg/h of high-strength strapping bands with a small cross-section, resulting in the cost-efficient use of raw materials.In addition to the live demonstrations there will also be presentations given by experts from Erema and Techno Plastic on the process and plant technology as demonstrated for the manufacture of PET strapping bands and PET filaments from washed PET bottle flake. The benefits of Vacurema technology instead of the conventional combination of individual units comprising crystalliser, drier and extruder, which save energy and costs in a single processing step, will be explained in detail. The symposium will be identical on both days and due to the international background of the participants expected to attend, the speeches will be delivered in English. For further information and registration documents please email Erema, mentioning PET Strapping Symposium: ch.dort@erema.at.The single-stage Vacurema Basic technology works with a patented vacuum reactor that features rotating tools and has a larger design especially for this application. It is linked to a single screw extruder system with high-performance degassing. The starting material, in this case PET bottle flake, is fed into the vacuum reactor directly via a vacuum lock without any precrystallisation or predrying. The material is then mixed, heated (though friction), dried, crystallised and volatile contaminants are removed simultaneously in a vacuum, all in one single pass. The downstream extruder plastifies and homogenises the material, degasses the melt and conveys it without an additional melt pump directly into a fine filter with an integrated, fully automatic self-cleaning system. The result is an extremely fine filtered melt which is then processed directly into PET strapping bands on the PET strapping system. The downstream plant technology of Techno Plastic then attends to the strapping process stage, starting with the nozzle unit and proceeding through the stretching, stamping, fixing and cooling station to the winder. The stretching technology demonstrated is flexible, based on many years of experience of the mechanical engineering company that specialises in extrusion systems for strapping bands and monofilaments. Combined for the first time with a Vacurema system for the material processing stage, there are considerable benefits for the user.As the compact Vacurema technology enables material processing with virtually no viscosity loss, higher stretching levels can be achieved for the strapping bands without sacrificing strength. This means that compared to conventional extruder processing, it is possible to increase productivity by up to 10 %, with the same band quality. In addition to this, due to the single stage approach of the Erema system, the specific power draw is approx. only half of a conventional extrusion system with upstream crystalliser and drier. The system can also process pure virgin material and mixtures of virgin material and bottle flake. Frequent product changes due to the respective application are made easier through the plant's fast retooling times.Turnkey plants for the direct and cost-effective production of PET strapping band and PET filaments from washed bottle flake with the combined Vacurema Tight Strap Technology will be offered in the future by both partners, Erema and Techno Plastic.
