Film shrinkwrappers

AFW ERGON Series

AFW 30 ERGON - Film shrinkwrappers up to 30 ppm

The AFW ERGON series is composed of automatic shrink wrapping machines to pack loose plastic, metal, cardboard or glass containers featuring a rectangular/square bottom (also oval or cylindrical by means of an ancillary device) and/or already made packs.

All AFW ERGON machines are equipped with a 90° product infeed conveyour and with a mechanical grouping system featuring a push-in device that slides on a brushless motor-driven linear guide. 

Depending on the model chosen, they can make packs in film only, cardboard pad + film, cardboard tray, cardboard tray + film.

AFW ERGON series packers achieve an output rate up to 40 packs per minute, according to the machine model and the type of product to be handled. The pack collations can vary according to the containers' shape, capacity and size; the most requested collations are: 2x2, 3x2, 4x3 and 6x4.

1An 90° product infeed conveyour, equipped with low-friction chains made of thermoplastic material, carries loose containers or already made packs to the pack formation zone, where the containers are clustered in the required format through a mechanical system made up of a pneumatic press and a product push-in device that slides on a brushless motor-driven linear guide.

2In P and T models, a corrugated cardboard pad or blank is picked from the blanks magazine by an alternate motion picker composed of a group of vacuum suckers. The pad or the blank moves along the blank climb and gently places itself underneath the group of products in transit with the long side leading.

3In the trayformer, special mechanical devices fold the blank’s front and rear flaps. The side flaps are sprayed with hot melt glue and then folded, thus forming the tray.

4The unwinding of the film reel, placed in the lower part of the machine, is controlled by a progressive brake, which ensures the film constant tension.

5Before the pack enters the shrinking tunnel, the film is wrapped around the container batch and overlapped at the base of the pack.


  • Machine bearing frame made of sand-blasted and powder-painted steel
  • The machine is equipped with sliding protection doors in anodised aluminium featuring a rounded shape which let all the motors (featuring low energy consumption) be placed externally if compared to the mechanical groups they activate. The closing system of doors is equipped with a slow-down device, which accompanies the door smoothly in its final phase of closure
  • Absence of gearboxes and prevailing employment of ICOS brushless motors equipped with digital servo-driver integrated into the motor
  • For life lubricated pads
  • Alternate motion cardboard blank picker, equipped with suckers
  • Before the pack enters the shrinking tunnel, the film is cut by a knife equipped with motorised blade and then wrapped around the group of containers and overlapped on the bottom of the pack. The adjustment of the film length is electronic
  • Compact knife group with film cutting blade driven by a direct drive brushless motorisation
  • The shrink tunnel features state-of-the-art technical solutions reducing energy consumption and ensuring an eco-friendly working process. The tunnel conveyor belt is made up of fibreglass bars, driven by side chains (®SMI). Thanks to the precise analysis of thermodynamic phenomena generated by the shrink process, the tunnel distributes hot air flows in an efficient and homogeneous way on the pack, thus ensuring its excellent quality at the end of the process. Shrink resistances are positioned on the side walls of the tunnel
  • Heat-shrinking tunnel with forced air ventilation

* The stated values are not binding, as they have to be confirmed by SMI according to the user's production conditions.
