Coating

Rolls of Film

High-quality coatings have a number of benefits, including glossy finishes, tactile feel, and slip/skid resistance. They can also provide a protective barrier against moisture, oxygen, and grease. But for these coatings to perform properly, they need to be able to adhere tightly to the substrate.

Corona treatment is the ideal solution for increasing the adhesion of coatings to substrates. Many substrates have low surface energy, meaning that coatings cannot easily adhere to the surface, leading to flaking and poor durability. Corona treatment works by exposing the substrate to a high voltage electrical discharge, modifying the substrate and substantially increasing its surface energy.  

The increased surface energy from the corona treatment process allows for much better adhesion of a wide variety of coatings, including: 

  • Paper wraps
  • Air knife coating
  • Blade coating
  • Curtain coating
  • Flexographic coating
  • Flood coating
  • Lithographic coating
  • Metering rod coating
  • Rotogravure coating
  • Size press coating
  • Tower coating

Many different substrates can be corona treated, including plastics, metals, and other non-porous materials. In addition to increased adhesion and durability, corona treatment provides many benefits, such as:

  • Enhanced printability, making it easier to print on the surface of the substrate.
  • Improved surface cleanliness, which reduces the risk of contamination and other issues that can impact product quality.
  • Improved surface uniformity, which can result in more consistent coating thickness and improved product appearance.
  • Reduced need for primers, which can reduce costs and simplify the coating process
