UV Coating: What Is It?

UV Coating is a process of applying thin layers of transparent, colorless UV curable polymers onto various surfaces. When exposed to ultraviolet light, the coating cures and becomes solid. It creates a glossy finish for any object to which it’s being applied.

UV coatings are used in manufacturing industries, including automotive, furniture, appliances, sports equipment, consumer goods, and custom packaging.

Now that we have a basic understanding, let’s jump into the process of UV coating.

The Process Of UV Coating

In the process of UV coating, many steps have to be taken. First, a substrate or surface must be selected and prepared for the coating.

The next step is applying a thin light-sensitive film onto a flexible base that will eventually become your product’s surface. That is done by applying a solution of UV curable monomers and oligomers onto the surface. The following are the different elements commonly used in UV coating:

  • Calcium
  • Carbonate
  • Kaolinite
  • Polyethylene

Once this is done, it must be exposed to ultraviolet light (UV) to start polymerization or curing.

When that step is finished, the surface will need to go through rinsing and drying before it’s completely ready for use.

Common Uses Of UV Coatings

UV coatings are an excellent solution that helps enhance custom packaging easily. It is usually found on corrugated and rigid boxes.

That is because these boxes are thicker and can carry the coating well. UV coatings add another dimension to the custom boxes.

One of the most common uses of UV coating can be found on luxury and gift packaging. UV and spot UV coating can make the packaging look elegant.

Regarding Spot UV coating, let’s see the difference between standard UV and spot UV coating.

Difference Between UV And Spot UV Coating

Spot UV uses the same process as standard UV; however, the difference is that the coating only focuses on a specific area of your custom packaging. It is usually used for logos.

Different Types Of UV Coatings

These different options allow you to choose a coating that best fits your needs. Let’s look at the details of these other options.

Matte UV Coating

Matte UV coating is a type of coating that gives your custom box a subtle finish. Of course, it will not be as dark and dull as the actual matte. However, it is still an excellent choice for those who like the classic look.

The matte coating is ideal for brands who want to make custom packaging with a vintage feel.

Gloss UV Coating

While matte UV coating gives off a more natural finish, gloss UV is perfect when you want your custom box to be more noticeable and eye-catching.

The glossy look of the custom packaging is trendy, especially in industries that require high visibility, such as food or cosmetics products.

Pearlescent UV Coating

This type of coating is perfect for those who want to make their custom boxes look elegant because pearlescent UV coating adds a lovely radiance that can only be described as luminous.

Orange Peel UV Coating

If you want your custom box to look like it’s been polished, consider using this type of coating.

The orange peel effect makes the packaging surfaces feel smooth and similar to the texture of an orange. This is not just for luxury boxes but can also be use on custom corrugated boxes that require a smooth finish.
