The 1.8 metre wide line – installed for an undisclosed processor – uses 9 extruders and a 9-layer die design to produce various barrier structures for the packaging industry to make film and bags. The 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 handles film thicknesses from 20 to 300 micron. According to Macro, the surface winder has zero fold-back roll starts and is able to auto-cut and transfer in both directions. It includes automatic shaft and roll handling and automatic shaft extraction.
Macro also said the installed control system includes the “readyrun” feature which allows to restore frequently used recipes at the push of a button. This can reduce changeover time, and improve the consistency of the products. The line is equipped with the “Green Energy” feature in which the energy consumption can be improved during the heat and cool process.
