Uniformity
Special Electrode Design
Uniform distribution of the discharge across the entire width of the film
High Performance
Film up to 9,000 mm
Uniform coating even on wide extrusion lines (agricultural film)
Reliability
Maximum stability
Electrodes designed to maintain a constant air gap during operation
Efficiency
Quick Format Change
Segmented electrodes and simple adjustments to reduce setup time
Designed for modern blown film extrusion lines
Uniform, stable, and consistent treatment even on wider lines.
Blown film extrusion lines require corona treatment systems capable of ensuring uniform discharge, high reliability, and continuous production throughout the entire extrusion process.
Me.Ro systems are designed to treat films up to 9,000 mm in width (agricultural film), with the ability to treat one or both sides of the material while maintaining a strictly constant Corona dose.

Electrodes designed to ensure uniformity and stability of treatment
System developed to maintain a constant air gap
Me.Ro electrodes are made of aluminum and designed to ensure maximum uniformity of the discharge distance across the entire width of the film.
The unique mounting system connects the electrode to the structure at multiple points on the upper beam, allowing for natural expansion during operation without altering theset Air-GAP.
The Swing Away system also allows the electrodes to automatically move away from the Corona roller when the film thickens, preventing potential damage.
Segmented Electrodes for Maximum Production Flexibility
Precise adjustment of treatment width and zones
Segmented electrodes are available upon request, allowing for independent positioning of each element, making it possible to quickly adjust the treatment width or select specific areas of the film.
The locking system holds the segments firmly in the set position, ensuring that the electrode adjustment remains perfectly unchanged throughout the entire production run.

A structure designed to ensure long-term reliability
Rugged components and simple adjustments for continuous operation
The high-rigidity structure ensures the stability of the Air-GAP.
The adjustment of theAir-GAP is performed directly from outside the hood, while the pneumatic opening facilitates film alignment and speeds up maintenance operations.
The Corona rollers, which are statically and dynamically balanced, incorporate speed sensors and safety devices that comply with EMC and CE regulations.
