Etind Corona Treater Sheet – High-Performance Surface Treatment Equipment

ElectroTech Industries sheet corona treater is widely used to treat PP,PVC and metallised polyester laminated sheets to increase surface tension and gives better printing and adhesion.

The Etind Corona Treater Sheet by ElectroTech Industries is a cutting-edge corona treatment system engineered to enhance surface energy on plastic sheets and films. Designed for superior performance, this industrial corona treater ensures improved ink adhesion, coating uniformity, and print quality across a wide range of substrates.

Ideal for industries like printing, packaging, and flexible film processing, this corona treater machine for plastic film is widely used for materials such as PP, PVC, LD, PE, OPP, foam, flex, and metallized polyester laminated sheets.

Why Choose Etind Corona Treater?

In modern printing processes using water-based and UV inks, untreated plastic surfaces often result in poor adhesion and low print quality. The Etind corona treater for plastic solves this problem by increasing the surface tension through controlled electrical discharge.

This high frequency corona treater modifies the molecular structure of the substrate surface, making it more receptive to inks, coatings, and adhesives—ensuring long-lasting and high-quality results.

Key Applications

  1. Corona Treater for Printing Industry – Enhances ink bonding and print clarity
  2. Corona Treater for Packaging Industry – Improves adhesion on flexible packaging materials
  3. Inline Corona Treater Machine – Suitable for integration with extrusion and coating lines
  4. Film Surface Treatment Machine – Ideal for plastic films and laminated sheets
  5. Corona Treater for Extrusion Line – Ensures consistent surface activation during production

Supported Materials

This plastic surface treatment machine is suitable for:

  1. Polypropylene (PP)
  2. Polyvinyl Chloride (PVC)
  3. Low-Density Polyethylene (LDPE)
  4. Polyethylene (PE)
  5. Oriented Polypropylene (OPP)
  6. Foam and Flex materials
  7. Metallized Polyester Films
  8. Other high and low-density plastic substrates

Specifications

Treatment Width 50mm-1200mm
Line Speed up to 80mtr./min
Electrodes Aluminium / Stainless Steel/ Ceramic Tubes
Roll covering Silicone Sleeve / Bare Roller
Roller Diameter 75mm

Salient Features

  • Specific power (energy density) kept strictly constant during running
  • Corona roller in aluminium covered in special silicon sleeves (other coatings can be supplied upon requests)
  • Special electrodes in aluminium/SS. The construction is made to guarantee uniformity of the air gap. The electrode is in fact connected to the structure not on the lateral sides but in many points on the upper beam of the station. This allows a free expansion when running
  • Easy air-gap regulation from outside the hood containing the electrode
  • Electrodes opened pneumatically for easy webbing up
  • Rollers statically and dynamically balanced
  • Speed sensor mounted on the corona roller
  • Safety switches shut down the power supply in case of accidental opening of the hood containing the electrodes
  • Electromagnetic (EMC) compatibility in accordance.
  • Possibility to have segmented electrodes. The segments can be individually moved away from the corona roller. The construction system is done in a way that allows an easy and fast setting of the partialization during a production change and moreover guarantees an absolute stability of the chosen position of the segments during running
  • High Stiffness of the structure holding the electrodes. Another important point for the stability of the air-gap

Advantages of Using Etind Corona Treatment System

  1. Improves surface adhesion for inks and coatings
  2. Enhances print quality and durability
  3. Reduces rejection and improves productivity
  4. Compatible with offset, flexo, and gravure printing
  5. Ideal for flexible packaging industry applications
