Crown impression treatment

Corona treatment to improve the adhesion of inks and coatings

At Aufer Solutions, we supply corona treatment systems, an essential technology in the printing and flexible packaging industry. Corona treatment modifies the surface tension of plastic substrates, films, and non-porous materials, allowing inks, varnishes, and adhesives to adhere evenly and durably.

Thanks to this technology, better print quality, reduced waste, and optimized production processes are achieved.

Features of crown treatment

  • Increased surface energy: improves wetting and adhesion of inks and coatings.

  • Compatibility with multiple materials: plastic films (PE, PP, PET, PVC), metallized foils, and coated papers.

  • Customizable systems: available in versions for production lines, laboratories, or specific applications.

  • Safe and efficient technology: low energy consumption and easy integration into production lines.

Advantages of corona treatment systems

  • Better print quality
    Enables more uniform, sharp, and durable colors.

  • Greater material versatility
    Enables working with a wide range of plastics and coatings.

  • Reduction in rejects
    Prevents problems with poor adhesion and defects in the final finish.

  • Easy integration
    Adapts to existing production lines without major modifications.

Applications of corona treatment

Corona treatment is applied in:

  • Flexographic printing and gravure printing on plastics.

  • Lamination and film coating.

  • Production of flexible packaging and labels.

  • Conversion and packaging processes in the food and pharmaceutical industries.

Frequently asked questions about coronavirus treatment

What is corona treatment in printing?

It is a process that increases the surface tension of plastics and films, improving the adhesion of inks and coatings.

Mainly plastics such as PE, PP, PET, PVC, and metallized or coated films.

If the ink does not adhere properly to the substrate, this treatment must be applied to improve print quality.

No. These systems are robust, low-maintenance, and have a long service life, provided that they are cleaned and inspected regularly.
