Better Bubble Stability For Blown Film

摘要

Macro Engineering & Technology Inc., which has stacked dual-lip air rings on top of each other since the early 1980s, recently developed a new version for improved output and film gauge with low-melt-strength materials like LLDPE and metal-locene PE. Macro's D10-B binary air-ring system has redesigned nozzles in the second ring that remove hot air from the bubble between air rings and replace it with cold air.
