Macro installs a 9-layer system in Europe
Macro installs blown film line with 9 extruders

Film and sheet extrusion machinery supplier Macro Engineering & Technology Inc. (Canada) has installed a state-of-the-art 9-layer system in Europe.  
 
The 1.8m wide line uses 9 extruders and a Macro proprietary 9-layer die design to produce various barrier structures for the packaging industry to make film and bags. This line is also equipped to run 18-layer structures. 
 
The line is designed to handle various materials including barrier resins such as polyamide, EVOH, PETg. The winding system is designed to handle film thicknesses ranging from 20um to 300um. The high performance surface winder has zero fold-back roll starts; it is able to auto-cut and transfer in both directions, and has automatic shaft & roll handling as well as automatic shaft extraction.  
 
The system was designed with features to further minimize waste and maximize energy efficiency. The Macro proprietary control system includes the “ReadyRun” feature in which the customer can restore frequently used recipes at the push of a button. This significantly reduces changeover time, and improves the consistency of the products.  
 
The line is also equipped with the “Green Energy” feature in which the energy consumption is optimized during the heat and cool process; the customer is able to view energy consumption in real-time. This feature helps them to know which recipes are the most efficient to produce.
