08/15 – Bandera blown film technology at Plast 2015

Bandera will participate to the next “PLAST” edition Bandera-blown-film-technology-Plast-2015(Milan, 5th – 9th May, 2015) with a wide exhibition area, showing an innovative 3-layer blown film co-extrusion line for the production of film for flexible technical packaging. This is mainly a modern line suitable for the extrusion of symmetrical structure film for lamination and flexible packaging. Additionally, an open house event will be taking place at our company headquarters in Busto Arsizio, in our new R&D facility “#TheHouseOfExtrusion”, as of 20th April, 2015, during which period we will be testing a new innovative 7-layer co-extrusion blown film line.

The running 3-layer blown film coextrusion line exhibited during the Plast Exhibition in Milan will feature the following design details:

  • Gravimetric dosing system
  • N.1 extruder TR 100 mm for the middle layer and n. 2 extruders TR 65 mm
  • Side feeding co
  • extrusion die
  • head and ø 300 mm die.
  • Advanced bubble cooling system (IBC), with dedicate management software (8 sensors)
  • Air cooling ring
  • Thickness measuring device with capacitive sensor
  • Bubble guiding cage with dust extraction system
  • Main rotating take off with flattening device made by carbon fiber rollers and 4 m long wood gusseting device. Additional cooling cylinders “S” wrap.
  • Additional take-off
  • Two station winding centre with back to back bridge configuration and different winding methods, according to the type of film to be produced: surface winding, axial winding with or without gap, and combined winding, in addition to the reverse winding mode.
  • Electronic structure with thermoregulation directly managed by PLC
  • Operator interface through color display industrial PC and line supervisor

On the other hand, the 7-layer blown film coextrusion line exhibited running in our new R&D facility “#TheHouseOfExtrusion”at our company headquarters in Busto Arsizio, will feature the following design details:

  • Gravimetric dosing system
  • N.1 extruder TR 50 mm for the middle layer and n. 6 extruders TR 65 mm
  • Side feeding co – extrusion die – head and ø 500 mm die.
  • Advanced bubble cooling system (IBC), with dedicate management software (8 sensors)
  • Air cooling ring
  • Thickness measuring device with capacitive sensor
  • Bubble guiding cage with dust extraction system
  • Main rotating take off with flattening device made by carbon fiber rollers and 4 m long wood gusseting device. Additional cooling cylinders “S” wrap.
  • Additional take-off
  • Two station winding center with back to back bridge configuration and different winding methods, according to the type of film to be produced: surface winding, axial winding with or without gap, and combined winding, in addition to the reverse winding mode.
  • Electronic structure, with thermoregulation directly managed by PLC
  • Operator interface through color display industrial PC and line supervisor

Furthermore, as Bandera is a real manufacturer of its own extrusion lines, visiting Bandera premises during the Plast Exhibition, it will be possible to see different parts of lines (e.g. die-heads, extruders, winders, etc.) both for packaging / converting applications and agrifilm / geomembrane lines (high-dimension machineries).
