Gruppo Colines, a builder of extrusion lines in Nibbia, Italy, has demonstrated a seven-layer, eight-extruder barrier cast film line running 2.1-meter-wide film with remarkably little edge trim—only 3%. More typical for an advanced barrier cast film line with edge encapsulation would be 8% to 10% edge trim.

Gruppo Colines, a builder of extrusion lines in Nibbia, Italy, has demonstrated a seven-layer, eight-extruder barrier cast film line running 2.1-meter-wide film with remarkably little edge trim—only 3%. More typical for an advanced barrier cast film line with edge encapsulation would be 8% to 10% edge trim. Gruppo Colines says it worked five years on the system, which includes dual gauge-control heads from Electronic Systems in Momo, Italy. Each head has two gauges—beta for thickness and IR to find the edge of the barrier for more accurate trimming. The system also uses a Superflex automatic die from Cloeren.
