Designed for modern BOPP and PET production lines
Uniform, stable, and consistent processing even on wide-width, high-speed lines
The film industry BOPP and PET has always been one of the main areas of specialization for Me.Ro.
Theexperience gained over more than 60 years has enabled us to develop corona treatment systems capable of ensuring uniform treatment, high reliability, and continuous production even on the largest extrusion lines.
Today, Me.Ro technology is used by some of the world’s leading manufacturers of BOPP and PET films, who have chosen it to achieve high performance, consistent treatment quality, and continuous production with downtime reduced to a minimum.

Electrodes Designed to Last
Designed to protect the Corona roller and maintain consistent treatment quality
The Me.Ro are designed to perform a slight rotation that allows them to automatically move away from the Corona roller in the event of film thickening or irregularities, preventing potential damage.
The unique design of the electrodes was developed to ensure maximum power transfer to the film, while keeping the electrode surface cleaner during operation. The electrode structure is also designed to compensate for thermal expansion that occurs during the process, helping to maintain a perfectly uniform air gap across the entire width of the film.
Simple and Precise Air Gap Adjustment
Fine adjustment to ensure uniform treatment across the entire width of the film
Special eccentrics distributed along the electrode allow for fine adjustment of the Air Gap, optimizing the distribution of the corona discharge and ensuring uniform treatment across the entire width of the material.
During operation, the corona dose is kept strictly constant.

A structure designed to ensure long-term reliability
Durable materials and integrated piping for maximum durability, cleanliness, and safety
The treatment plant is built entirely from ozone-resistant, selected to ensure reliability and long service life even under the most demanding operating conditions.
The pipes dedicated toozone are fully integrated into the structure, contributing to a cleaner, safer, and more easily accessible design for maintenance operations.
High-Performance Insulators
Components designed to withstand electrical and mechanical stresses
The Me.Ro isolators are designed to ensure the proper operation of the treatment plant and contribute to the stability of the process.
In addition to providing electrical isolation, they also perform an important structural function and are designed to withstand the mechanical and electrical stresses generated during plant operation.
