The supplier demonstrated five film lines, two of which were introduced at the in-house event. One new line, the Optimex 3-layer blown film line, is equipped with newly designed components such as extruders, gravimetric weighing and dosing, a Maxicone C die and a film sizing cage. W&H also unveiled its new Aquarex line, which uses a water film to rapidly cool the film bubble and provides improved transparency, toughness and more pleasant tactile properties.
The manufacturer also rolled out a new Opticool air ring system and the Filmatic N film winder, the latter of which is available for film widths of up to 360 centimeters (141.73 inches) and is capable of center, gap and surface winding. W&H also demonstrated a monoaxial film stretching unit (MDO) and nanolayer technology for stretch film production on a Filmex cast line.
