A cylinder of water-cooled metal inside the bubble of a dedicated blown film line producing heavy-duty shipping sacks increases output by 30-40%, to over 600 lb/hr, says Kiefel Extrusion GmbH in Germany (U.S. offices in Wrentham, Mass.). Kiefel's Enhanced Cooling Package (ECP) is a module about 1.8 meters tall, which keeps the IBC air cool, rather than being heated by the bubble.

A cylinder of water-cooled metal inside the bubble of a dedicated blown film line producing heavy-duty shipping sacks increases output by 30-40%, to over 600 lb/hr, says Kiefel Extrusion GmbH in Germany (U.S. offices in Wrentham, Mass.). Kiefel's Enhanced Cooling Package (ECP) is a module about 1.8 meters tall, which keeps the IBC air cool, rather than being heated by the bubble. The module is sized to leave only a narrow gap for IBC air to pass between it and the bubble. The current model can be retrofitted onto Kiefel Kirion blown film lines for form-fill-seal bag production. It fits a 175-mm die and bubble with a low BUR (1.8 to 2:1). Kiefel has made five installations. ECP may later be adapted to other bubble sizes. It will be launched in the U.S. at NPE in Chicago.
