Three rigid film/ sheet extrusion projects coming up for delivery shortly to key converters operating in Eastern Europe are exemplary of the capabilities Costruzioni Meccaniche Luigi Bandera SpA (Busto Arsizio, Italy) in film and rigid sheet extrusion:
1. Compact, Multilayer PET Rigid Film/ Sheet Extrusion Line for thermoforming and FFS (Form Fill & Seal), for a maximum output of 750 Kg/h, with a net width of 1200 mm, installing a Bandera patented, 2C70 52 L/D co-rotating twin-screw main extruder, a TR65 35 L/D single-screw co-extruder, a single-manifold flat die, a horizontal roll stack. The line is completed by thickness control, in-line PE lamination and two-position cantilever winding systems.
2. Versatile high-output, Alpha 2 – 185 Rigid Film/ Sheet Extrusion line, mainly for multilayer PET extrusion, but suitable for processing also PP, PS and PLA. Its maximum output in terms of PET processing is 1600 Kg/h, with a net width of 1580 mm. This line features a Bandera patented 2C105 52 L/D co-rotating twin-screw main extruder, a TR90 35 L/D single-screw co-extruder, an automatic Bandera single-manifold flat die, a horizontal roll stack with motorized cross axis system for thin film/ sheet processing, a thickness control system and an in-line PE film lamination system.

3. Sophisticated, extremely high-tech, high-output, multilayer sheet extrusion line for rigid or foam PET production for thermoforming, form-fill-seal (FFS), printing and industrial applications. It is designed for a net width of 1500 mm and has a maximum output of 1500 Kg/h rigid PET, and 750 Kg/h in terms of semi-rigid PET. This line involves two co-rotating twin-screw extruders, a 2C85 52 L/D and a 2C70 52 L/D, a TR90 35 L/D single-screw co-extruder, two flat dies, i.e., a Cloeren flat die for rigid products and a Bandera flat die for foamed/semi-rigid products, a physical foam PET extrusion system, a horizontal roll stack with cross axis system for thin film/sheet processing, besides systems for thickness control and semi-automatic cantilever winding.
This line also comprises an in-line PE film lamination unit that is a dedicated unit suitable for semi-rigid products as well. This line represents Bandera technology at its best in terms of design, products and performance. It is the fourth Bandera line commissioned by this customer.
