Uniformity
Special Electrode Design
Uniform distribution of the discharge to ensure consistent treatment across the entire width of the material.
High Performance
Film up to 7,000 mm
Designed for processing cast films up to 7000 mm in width, with configurations available for processing on one or both sides of the material.
Reliability
Premium Facility
Sturdy construction, ozone-resistant materials, and components designed to ensure long service life and uninterrupted production.
Efficiency
Low Maintenance
Simple adjustments, high accessibility, and quick maintenance to reduce machine downtime.
Designed for modern cast film lines
Consistent performance even at maximum treatment widths.
The Cast Film require corona treatment systems capable of ensuring uniform discharge, high reliability, and production continuity even at high production speeds.
Me.Ro. systems are designed to treat films up to 7,000 mm in width, with the ability to treat one or both sides of the material while maintaining a strictly constant Corona dose throughout the entire process.
The combination of special electrodes, a high-performance Corona roller, and a highly rigid structure ensures consistent treatment quality and maximum operational stability.

Electrodes designed to ensure stability and long service life
AISI 316 stainless steel and Swing Away system for maximum protection.
Me.Ro. electrodes are made of AISI 316 stainless steel and designed to naturally compensate for thermal expansion without altering the set Air-GAP.
Theexclusive Swing Away system allows the electrodes to automatically move away from the Corona roller in the event of film thickening caused by theextruder, preventing damage and ensuring uninterrupted production.
Simple and Precise Air-GAP Adjustment
Quick Check of Discharge Distance and Simplified Production Changeover
Adjustment of theAir-GAP is performed directly from the outside of the hood, allowing for simple and precise adjustments.
The pneumatic opening mechanism facilitates film feeding, reducing setup time and improving accessibility during maintenance operations.

A structure designed to ensure long-term reliability
Maximum mechanical rigidity and components designed for the highest production rates.
The electrode support structure is designed with high rigidity to ensure the stability of theAir-GAP during operation.
The Corona rollers, which are statically and dynamically balanced, can be coated with silicone rubber or insulated ceramic and are supplied with a protruding shaft for motorization.
The design of the pressure roller is optimized to prevent counter-treatment of the film and ensure the highest quality of Corona treatment.
