VACUREMA Inline Strapping Review Brochure

Take advantage of the newVACUREMA Inline-Strapping-Technology:LESS ENERGY + LOW MATERIAL COSTS = HIGH QUALITY PET STRAPPINGLATEST NEWS UPDATE:MORE OUTSTANDINGTEST RESULTSREVIEWOPEN HOUSE 2008 – PET Inline-Strapping2TABLE 1: Five different representative examples of PET strapping production applications using VACUREMA inline strapping band technologyhe new VACUREMA inline strapping solution already achieved sensational results in the tests carried out as part of theOpen House event. EREMA has also taken full advantage of the time since for a number of customer trials with variousgrades of starting material. The results have been astounding. Regardless of the quality of the material to be processed, we have alwaysoverfulfilled the requirements of the market. And the last thing we want to do is keep these impressive results to ourselves:LATEST NEWS UPDATE:MORE OUTSTANDING TEST RESULTS1) In this (non-standardized) test, 20 specimens are subjected to defined flexing in a direction longitudinal to the stretching direction in order to estimate the splicing behaviour of the strapping on the basis of the fracture pattern observed.Parameter Material 1 Material 2 Material 3 Material 4 Material 5Input materialMaterial type PET flakes PET flakes PET flakes PET flakes PET repelletsPre-treatment cold washed hot washed cold washed hot washed from BOPET filmIntrinsic viscosity (IV) [dl/g] 0.75 0.77 0.70 0.69 0.60Bulk weight [kg/m3] 280 300 300 200 850Residual moisture [%] 0.38 0.46 1.45 1.01 0.20PVC content [ppm] 549 223 6 14 -Polyolefine [ppm] 45 38 30 456 -Cellulose [ppm] 3 - 591 - -Adhesives [ppm] - - 2,235 357 -Other contaminants oil residue oil residue 20 ppm oil residue -sand 66 ppm PET-GConditioned melt / Process parametersMelt IV value [dl/g] 0.73 0.76 0.70 0.64 not measuredFilter fineness [µm] 60 60 60 60 60Throughput [kg/h] 305 290 304 317 314PET strapping, embossedDegree of stretching [%] 570 570 541 546 570Tensile strength [N/mm2] 517 - 548 538 480 510 422Elongation at tear [%] 12 - 15 12 - 15 15 15 12 - 15Breaking strength of strapping [N] 6,480 - 7,250 6,672 6,398 6,908 5,299Strapping cross-section [mm x mm] 15.75 x 0.80 15.9 x 0.78 15.5 x 0.86 15.75 x 0.86 16.1 x 0.78Strapping weight [g/m] 16.98 15.9 16.8 17.5 15.4Splicing behaviour 1) 18 / 2 19 /1 19 / 1 20 / 0 18 / 2[without / with fracture]Specific energy consumption 0.660 0.660 0.680 0.646 0.620of overall system [kWh/kg]3Industry-leading low overall specific energy consumption of 0.65 kWh/kgIndustry-leading low overall specific energy consumption of 0.65 kWh/kgCountless experts from around the wholeworld who wanted to know more aboutour new strapping technology contactedus after the symposium as well," says oneof EREMA CEOs Manfred Hackl. "We cannow offer PET strapping producers aperfectly configured and turnkey overallsolution."EREMA CAUSES A SENSATION WITHNEW STRAPPING TECHNOLOGY:High-strength PET strapping from low quality post consumer PET flakesIN ONE STEP FROM PET BOTTLE FLAKE TO HIGH-QUALITY STRAPPING? Industry-leading low overall specific energy consumption of ˜ 0.67 kWh/kg, no pre-dryers or cristallisersnecessary? Increased production stability due to stable and high IV? High-quality strapping from low-quality input material? Superior plant flexibility by processing different input material: PET bottle flake, PET virgin material,PET sheet production waste, PET strapping production waste or mixtures of this materials in any ratiohe Open House, held by the Austrianproducer of recycling systemsEREMA on 26 and 27 October 2008,was fully focused on a specialist sym-posium on the subject of PET strapping.Together with the Italian companyTechno Plastic s.r.l., EREMA presentedthe outstanding performance of thenew VACUREMA strapping technologyfor the first time ever under productionconditions.From washed post consumer PET flakesto high-strength PET strapping in just asingle step: 25% lower material costs anda good third of energy saved comparedto conventional systems with comparablequality left over 150 specialists from 17countries truly astounded.This quantum leap was made possible bya further development of the proven EREMAextrusion system VACUREMA, whichensures PET flake processing with stable IV.Thanks to this system, energy and spaceconsuming predryers or crystallisers arenot necessary."The exceptionally high level of interestand positive feedback regarding thisparticular topic and highly specialisedmarket segment has confirmed our course.TABLE 2: Types of PET strapping production equipment currently available in the market: An overview of key reference data(PET flake processors)2) According to Reimotec presentation of November 14, 20083) According to Sima documentation of December, 20074) According to Sima presentation of September 30, 20085) Depending on overall contamination - compare customer-specific base facts in table 1Subject to technical modifications.
