The patented Evolution Ultra Flat film flattening unit integrated in the take-off is an essential module used to enhance the quality. Ultra Flat is able to correct surface irregularities occurring in the production of blown film.
Surface irregularities are inherent to the film blowing process. They can occur to a greater or lesser extent in the production of packaging film, depending on film dimensions and structures. The resulting waves can cause serious problems in winding and conversion. Reifenhäuser Blown Film has the right solution: With Evolution Ultra Flat a web of optimum flatness can be produced due to minimised stretching of the film via heating-cooling rolls - a prerequisite for winding and conversion on downstream equipment.
Film producers around the world appreciate the Ultra Flat innovation. Especially the Asian market has responded to the newest Reifenhäuser technology with investments in the future: The first blown film line equipped with the Ultra Flat system came on stream in Vietnam about 22 months ago. Further orders followed soon. The superior line configuration convinced both the owners and other interested customers outside Vietnam: Over the past six months Reifenhäuser recorded orders from Asia for a total of five new blown film lines equipped with the Ultra Flat flattening unit.
Ultra Flat scores in many different respects: With an especially unproblematic conversion of the film, whether in laminating, printing, re-forming, packaging or sealing operations. It enables the packaging industry to benefit from the increased efficiency throughout the whole value chain - thanks to webs of optimized flatness produced on Reifenhäuser Blown Film lines.
