What is UV coating in Packaging?

UV coating is a clear liquid applied to paper that is cured using ultraviolet light to give the surface a high gloss finish.

This process is done using a UV coating machine after printing.

UV coating can bring your artwork to life and give your packaging design a sleek look.

Let’s examine the UV process in detail and explore how you can use it in your custom packaging project.

The Process of UV Coating:

UV coating is a widely used finishing process for packaging

They are a clear liquid compound made up of calcium carbonate, kaolinite, and polyethylene, which help to bond the coating to the packaging surface.

The compound can be applied using a silkscreen or roller, and once it is wet, it is cured with ultraviolet light to quickly dry it.

UV coatings are water-resistant and can be applied to all or only certain surfaces of the packaging, depending on the desired outcome.


Explaining Spot UV Coating

Spot UV refers to a printing method that uses a liquid compound similar to UV coating, but only applies it to certain areas of the packaging rather than the entire surface.

This technique can add depth to the design by highlighting specific features such as logos, text, or images.

The Various Applications of UV Coating

UV coatings are often used on a variety of paper products, but they work best on thicker, heavier paper such as rigid boxes and corrugated packaging.

These coatings can enhance the appearance of artwork and are often used on luxury packaging to give it a high-quality feel.

UV coatings are also becoming more popular in the e-commerce industry because they can increase the tensile strength of packaging during transportation.

Classification of UV Coatings

There are several types of UV coatings available to suit different design preferences.

Gloss UV

Gloss UV coatings provide a high level of shine and are best used for spot UV printing to avoid creating a highly reflective surface.

Matte UV

Matte UV coatings offer a feeling of elegance and luxury, but may show fingerprints.

Pearlescent UV

Pearlescent UV coatings have a lustrous, iridescent finish created by combining gloss UV coatings with metal flecks.

Orange Peel UV

Orange peel UV coatings have a raised design and textured finish that adds visual and tactile interest to packaging.

UV Coating: Pros and Cons

There are several pros and cons to consider when using UV coating:

  • Attractive and bold appearance:UV coating creates a high gloss finish that can enhance the visual appeal and perceived value of the packaging or product.
  • Scuff resistant:It offers better scuff resistance than aqueous coatings and varnishes. UV coatings can resist abrasion well, though the specific type of coating may affect smudge resistance.
  • Fast drying:Quick drying can help reduce lead time and improve overall efficiency.
  • Chemical burning: Depending on the PMS color used, UV coating may be prone to chemical burning.
  • Compromised quality and appearance:If the printing process is not properly set up, the print output may be defective.

Overall, UV coating can give your product a sleek and premium appearance and is a good choice if you want to make a strong first impression. However, it’s important to consider the potential drawbacks, such as the risk of chemical burning and potential for compromised quality.
