Canadian film and sheet extrusion systems manufacturer, Macro, will showcase its latest 9-layer blown film coextrusion die at the upcoming NPE show. The die is an adaptation of the manufacturer’s TaperPack stackable die design, which Macro uses on smaller-diameter blown film lines as well as its double and triple bubble lines. The key adaptation to this latest design is the extruder adaptor heights are all level. With a short residence time and the ability to carefully control temperatures and layer thickness, the die provides the processing flexibility that allows for a wide array of product changes that include barrier structures comprised of PA and EVOH.
