Kiefel Extrusion: Enhanced Cooling Package
The newest development from KIEFEL Extrusion is the ECP (Enhanced Cooling Package), which will be among the exhibits presented to trade professionals at the PLAST fair in Milan, from February 14 to 18. The machinery manufacturer based in Worms has developed ECP especially for the production of heavy duty bags. Interested visitors will find KIEFEL, together with its representative company SIRT, at the fair center in Rho-Pero at Stand B/C 16/15 in Hall 9. The German blown film specialist is ideally prepared for the Italian market: after all, more than 20 percent of the heavy duty bags made in Europe come from there.
Capable of integration in all of KIEFEL’s KIRION® lines, the system in particular allows for high throughput performance of more than 300 kg/h, with the typical tube measurements for bag production of 535 mm x 140 µm (lay-flat width x film thickness). This very good result in the throughput performance is by no means self-evident. Although heavy duty bags that are intended for filling with bulk products such as pet food, fertiliser products or granulate still are treated as commodity products, their production requires a significant amount of know-how and expertise. “Our customers who have already seen the system in operation at our laboratory were impressed by the values of thickness tolerance, stiffness and sealing properties or also by the tear resistance and penetration strength of the heavy duty bags produced”, KIEFEL managing director Edgar Gandelheidt reports of the pleasing test run with the Enhanced Cooling Package. “Worldwide, but especially in Italy, where we have already sold 14 lines since the introduction of the KIRION® range, the new module now holds promise of creating exceptionally interesting additional business”, Gandelheidt continues.
The KIEFEL KIRION® blown film lines are proven technology, and include universal 30 L/D screws, allow film producing customers to process the widest possible range of polymers (PE LD, PE-LLD, PE-HD or PP) without any problems. They can count upon the C3 profile control system that reliably maintains close thickness tolerances. Additional cooling devices such as two sets of nip rollers and a set of S-wrap cooling rollers which are installed in the KIRION® T film take-off avoid, together with KIRION® W winders, breaking of the folded edges and enable winding without blocking of the film, even with large reel diameters.
