Corona Treater For Metallized Films Or Foil

Precision Treatment for Metallized Films & Foils

High-Purity Ceramic Electrodes by Anjali Corporation

Unlock the ability to treat conductive substrates without arcing. Our advanced ceramic electrodes deliver a high-density, uniform corona discharge, ensuring perfect adhesion on metallized films, aluminum foils, and high-speed converting lines.

Product Overview

The Solution for Conductive Substrates

Standard metal electrodes cannot treat metallized films because the conductive surface causes direct arcing (short circuits).

Anjali Corporation’s Ceramic Electrodes solve this by acting as the dielectric barrier themselves. Made from high-purity Alumina (), they allow for powerful, consistent corona discharge directly onto conductive surfaces without damaging the film or the generator. Whether you are running a high-speed laminator or a metallizer, these electrodes are the industry standard for performance.

  • Treats Conductive Materials: Specifically designed for Metallized Polyester (MET-PET), Metallized BOPP, and Aluminum Foil.
  • High-Density Discharge: Provides a finer, more uniform corona curtain compared to metal fins, resulting in higher dyne levels at lower power settings.
  • Corrosion & Oxidation Proof: Unlike aluminum, ceramic does not corrode or deform under high ozone exposure, ensuring a significantly longer service life.
  • Thermal Stability: Excellent heat dissipation properties prevent warping even during continuous 24/7 operation.
  • Universal Compatibility: Can be retrofitted into existing corona stations (replacing metal fins) to upgrade line capabilities.

Essential for High-Value Converting:

  • Metallizing Plants: Post-metallization treatment to ensure ink anchorage.
  • Aseptic Packaging: Treatment of aluminum foil laminates.
  • High-Speed Printing: Rotogravure and Flexographic printing on metallized substrates.
  • Lamination: Solvent-less lamination of foil to plastic films.

Maximizing Ceramic Electrode Life

  • Handle with Care: Ceramic is brittle. Never tighten mounting screws excessively; use spring-loaded clips to allow for thermal expansion.
  • Keep it Clean: Dust and humidity can create conductive paths. Clean the electrodes regularly with Isopropyl Alcohol (IPA) and a soft cloth.
  • Check Airflow: Ensure your ozone extraction blower is working efficiently. Ceramic electrodes generate significant heat and require constant airflow to prevent cracking.

Great technical descriptions of the machines and treatment process. The product brochure link is helpful. Still, the overall design feels a bit basic — improved layout and images could make the browsing experience better.”

The website has all key business info and product lists available, but navigating between pages isn’t immediately intuitive. More clear menus and responsiveness on mobile would improve usability.

The site provides solid information about Corona Treater systems and their applications, and contact details are easy to find. However, some sections feel dated and could benefit from more modern visuals and updated content.
