Newly formed Reifenhauser Kiefel, Danvers, Mass., has developed an air ring that provides two-directional cooling, meaning that air is directed upward to the air lips and downward to an additional air exit closer to the die. The company says this offers a level of bubble stabilization and output more typically found in dual air-ring setups while improving film properties such as transparency and gloss.
