Converting Line Corona Treater Manufacturer India

Corona Treater Converting Line – High-Performance Surface Treatment System

In modern converting industries, achieving superior print quality and strong lamination bonding depends heavily on effective surface treatment. A Corona Treater Machine plays a critical role in enhancing surface energy, ensuring excellent adhesion for inks, coatings, and adhesives across a wide range of substrates.

What is a Corona Treater?

A Corona Treatment System is an advanced Surface Treatment Equipment used in converting lines such as rotogravure printing, flexographic printing, lamination, coating, and extrusion processes. It increases the surface energy (dyne level) of materials like plastic films, metalized substrates, and foils, enabling better bonding and print results.

ElectroTech Industries offers a high-performance Industrial Corona Treater designed to operate efficiently at very high line speeds while maintaining consistent treatment quality.

Why Corona Treatment is Essential

In industries like printing and flexible packaging, untreated or low-dyne materials can cause:

Poor ink adhesion
Weak lamination bonding
Reduced production speed
Inconsistent product quality

A Film Surface Treatment Machine ensures:

Improved surface wettability
Strong adhesion for inks, glue, and coatings
Smooth high-speed operations
Consistent production output

This makes it an essential Corona Treater for Printing Industry and Corona Treater for Packaging Industry applications.

Applications of Corona Treater
