CHAANG HORNG Sets the Global Standard in Surface Treatment

In the high-speed worlds of flexible packaging, film extrusion, and printing, a flawless production line can quickly turn into a downstream nightmare if the ink starts flaking or the lamination refuses to stick. The culprit is almost always surface tension. When a substrate’s dyne level isn’t optimized, the production value drops to zero.

Enter the unsung heroes of the production line: the Corona Treater and the Anti-Static Eliminator.

For over 35 years, Taiwan-based CHAANG HORNG ELECTRONIC CO., LTD. has been setting the global benchmark for this essential technology. Founded in 1988, the company has become a pioneer in corona and plasma technology, boasting more than 12,000 installations globally and solving complex adhesion problems across multiple industries.

The Science of Sticking: Corona Treaters

Plastic films and metalized surfaces naturally have low surface energy, making it difficult for inks, coatings, and adhesives to bond properly. CHAANG HORNG’s Corona Treaters solve this by using a low-temperature corona discharge plasma to modify the surface properties of the material.

By increasing the surface adhesion dynamically as the film passes through the line, manufacturers can ensure perfect printing and laminating results. The company has engineered a highly versatile lineup to meet varying production needs, including:

• T Series / TE-A Series: Optimized for blown film lines.
• THH Series: Designed for high-speed printing environments.
• TRB Series: Engineered specifically for label printing.

CHAANG HORNG’s philosophy relies on three core pillars: making their machines Simple (user-friendly and easy to integrate), Reliable (capable of 24/7 operation with heavy-duty frames), and Affordable (focusing on high treatment levels without unnecessary, flashy designs that inflate maintenance costs).

Clearing the Charge: Anti-Static Eliminators

Static electricity is a notorious byproduct of plastic film and paper processing, attracting dust, causing jamming, and creating hazardous shocks for operators.

To combat this, CHAANG HORNG manufactures industrial-grade Anti-Static Eliminators, including Transformer models, CQ Types, and Extended CSL Types. These devices are critical for neutralizing static on PP, PS, PE, and PET materials, as well as electro-plating films, ensuring that the production line runs smoothly without sudden static-induced stoppages.

A Legacy of Innovation

"With every installation, our goal is to offer solutions, solve problems, and minimize downtime," the company states. By constantly refining their equipment based on real-world operator feedback, CHAANG HORNG has managed to stay one step ahead of industry demands.

Today, whether a facility is producing standard packaging films or highly specialized release papers, CHAANG HORNG remains the trusted engine working quietly in the background—ensuring that when things need to stick, they do.
