Blown film extrusion

Short description

  • Treatment of materials during the extrusion process
  • Single, double or 4-sided web treatment
  • Different versions available for:
    • Installation on a winder
    • Installation on a platform
    • Budget applications


  • AVB-100G
  • AVB-100D / AVB-120D
  • AVB-150G
  • AVB-150C
  • AVB-200E



Segment electrodes (Standard)

Enables strips of corona to remain untreated in the running direction, to maintain the material weldability. Various minimum widths available.

Stainless-steel electrodes (Standard)

Suitable for an effective and homogeneous treatment of technical foils.

Electrodes pivoting in running direction

This prevents the electrode system being damaged from inevitable impediments in the web material.

Electrode housing with metal enclosure

Lowest possible EMC levels, no fire-hazard, large high-voltage clearances ensure that no flashovers or creepage discharges can occur through moisture or contamination when compared with electrodes using plastic shielding, long lifetime.

High-voltage transformer, mounted directly onto the electrode housing, no external high-voltage wiring

Avoids electric shocks, fires and interference radiation

Treatment and nip rolls (Order-specific)

Avoid slippage and reverse-side treatment

Silicone or ceramic dielectric

Spray-gap can be set from the outside

Ceramic high-voltage insulators

No danger of creepage discharges or incineration, unlike Teflon or other plastic material insulators. High degree of inherent safety.
