Extrusion Line Corona Treater Manufacturer in India

Electro Tech Industries (ETIND) is a trusted Corona Treater Manufacturer in India, offering advanced Corona Treater Machines and Corona Treatment Systems for blown film and cast film extrusion lines. Our high-performance Surface Treatment Equipment is essential to achieve the required surface energy before further processes like printing, coating, and lamination.

Without proper Corona Treatment, extruded plastic substrates such as BOPP, PET, LDPE, and polypropylene films cannot support downstream converting processes due to low surface energy. ETIND’s Corona Treater for Plastic ensures improved wettability, enabling strong bonding of inks, adhesives, and coatings.

Corona Treatment System for Extrusion Coating & Lamination

Our Industrial Corona Treater is widely used in extrusion coating and lamination plants to enhance adhesion of thin layers of polyolefins (LDPE, PP) on various substrates including paper, textile, woven materials, jute cloth, aluminium foil, BOPP film, and polyester film. Proper pre-treatment ensures excellent bonding strength and superior product quality.

The Film Surface Treatment Machine increases surface energy effectively, making it ideal for applications where natural surface tension is insufficient for proper wetting and adhesion. This makes ETIND systems highly reliable for both the Printing Industry and Packaging Industry.

High-Performance Corona Treater for Extrusion Lines

ETIND’s Corona Treater Machines are designed to deliver uniform and consistent treatment across the web. Installed directly on blown film or cast film extrusion lines, these systems improve adhesion properties during the production stage itself, ensuring smooth downstream processing.

Our systems are built for continuous operation, easy maintenance, and stable performance, making them a preferred choice in the Corona Treater India market. With precision engineering and robust construction, ETIND ensures uninterrupted production with optimal watt density control.
