Co-extrusion systems of varying degrees are available and sized to match the many line sizes available with respect to desired layer percentages, film thicknesses and operating line speeds. Co-extruded films from 3 to more than 20 layers ("micro layers"), are available, 5 layers with 4 extruders and 7 layers with 5 extruders are most common. Film forming is typically by vacuum box on a large diameter chill roll to control film pre-stretch properties. Winding systems feature fully automatic roll and core handling systems.
