Corona Treater System for Surface Energy Treatment

High Frequency & High Performance Corona Treatment System

A Corona Treater System is an advanced surface treatment solution designed to increase surface energy on materials such as plastic films, foils, paper, and laminates. By exposing the surface to a controlled high-frequency electrical discharge, the system significantly improves wettability and enhances adhesion for inks, coatings, and adhesives.

This process is essential in modern industries where high-quality printing, coating, and bonding are required. A properly treated surface ensures consistent results, reduced defects, and improved product durability.

What is Corona Treatment?

Corona treatment is a surface modification technique used to improve the bonding characteristics of low-energy materials like polyethylene, polypropylene, and other polymers. These materials naturally resist adhesion, making treatment necessary before printing or coating.

The system works by generating ionized air (corona discharge) between an electrode and a grounded roller. As the material passes through this air gap, its surface structure is altered at a molecular level, increasing surface energy and enabling better ink and adhesive bonding.


Key Benefits of Corona Treater Systems

  • Enhances ink adhesion for printing applications
  • Improves coating uniformity and bonding strength
  • Increases surface wettability of plastic materials
  • Reduces rejection rates and production issues
  • Supports high-speed industrial processing
  • Ensures consistent treatment across web width
