Corona Treater For Multilayer Films

High-Performance Surface Treatment for Multilayer Films

Ensure Perfect Lamination & Printing Adhesion with Anjali Corporation’s Advanced Corona Systems.

Engineered specifically for 3-Layer, 5-Layer, and 7-Layer Blown Film Lines, our treaters deliver consistent dyne levels across the entire web width, handling high line speeds and complex polymer blends with ease.

Product Overview

The Anjali Multilayer Advantage

Multilayer films (utilizing materials like EVOH, PA, and mLLDPE) require precise surface tension control to ensure high-quality converting. Anjali Corporation’s Multilayer Corona Treater is designed to prevent backside treatment and pinholing while delivering uniform corona discharge.

Our systems feature a robust Double-Side Treater Station coupled with a high-efficiency IGBT Control Panel, ensuring your production line runs uninterrupted with zero wastage.

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.
