evolution ultra fusiontwinscrew technology demonstrates its advantages in the production of multilayer blown film. worms, june 2014 evolution ultra fusion, the first direct extrusion technology for the production of multilayer blown films boosts productivity and energy efficiency, reduces production costs and improves film properties. tests conducted under productionoriented conditions in the technology center of reifenhäuser kiefel extrusion confirm the competitive advantages initially presented at k 2013 under the motto rethinking technology. now, the technology will be further developed for commercial use. the evolution ultra fusion technology processes raw materials directly &ndash without previous predrying and compounding. for this reason, the engineers came up with the concept of integrating a twinscrew extruder of the reitruder series directly in a blown film line. compared with the processing of compounds and masterbaches, the direct extrusion technology can reduce the production costs for 3layer blown films by more than 15 percent. the technology shows its full savings potential particularly in the production of filled multilayer films in which expensive raw materials like polyethylene, are replaced in part with lowerpriced fillers such as calcium carbonate caco3. the evolution ultra fusion technology enables producers to process especially high filling amounts of up to 50 percent. this allows them to reduce their production costs by about 20 percent. in addition to cost savings, the high filling amounts have a positive effect on the film properties film strength and film stiffness are increased while elongation is reduced. furthermore, special properties can be obtained with this technology, for example those needed for the production of breathable films.together with a partner from the industry, reifenhäuser kiefel extrusion is developing products for industrial use to bring the technology to themarket. evolution ultra fusion can already be tested by customers in the world&rsquos largest technology center for the production of nonwovens, films and wood polymer composites at the company&rsquos site in troisdorf. sascha skora, senior sales manager, says "many customers are using the testing possibilities offered by our research and development center. the technology is widely accepted because of the high savings potential and the opportunity it offers for entering new markets demanding highquality films. with evolution ultra fusion, these high demands and special film properties can be realized, reliably and efficiently.&ldquo examples of applications for the evolution ultra fusion technology packaging bags for flower soil and peat compression bag film breathable and nonbreathable diaper backsheets breathable film bio film, for example pla plus filler photo the reitruder twinscrew extruder in a blown film line boosts productivity and energy efficiency and enables the use of 50 percent of fillers, thanks to the direct extrusion.schematic drawing a typical line configuration of the innovative evolution ultra fusion technology by reifenhäuser kiefel extrusion.about reifenhäuser kiefel extrusion gmbhwith more than 60 years of experience and more than 7,000 lines installed worldwide, reifenhäuser kiefel extrusion, a subsidiary of the reifenhäuser group, is one of the world&39s leading providers of blown film extrusion lines and other equipment for the production and subsequent processing of high quality plastic films. newly launched in 2010, the new evolution product series covers the entire spectrum of blown film, from mono to 11layer lines. the technology can be used for production in simple packaging applications, but is equally well suited for manufacturing complex, hightech films and food packaging with special barrier properties. the company employs around 220 employees at its sites in worms and troisdorf. for technical questions refer toeugen friedelreifenhäuser kiefel extrusion gmbharea sales director und marketing manager 67547 worms&bull germanytel. 49 06241 902184eugen.friedel@reifenhauserkiefel.com  reproduction free of charge &ndash please send voucher copies to the attention of otto kuhlwords 417, characters in main body 2450  reifenhäuser kiefel extrusion gmbhcorneliusheylstraße 49 &bull 67547 worms &bull germanytelefon 49 06241 9020 &bull telefax 49 06241 902100internet www.reifenhauserkiefel.com
