Paper Coating Operation

Once the wet coating is applied, it is cured with UV light and after a few seconds, the coating is completely dry. UV coating has water-resistant properties, making it a common choice for protecting the durability of packaging surfaces.
UV coating can be applied to all box surfaces or only to specified surfaces.
What are the common uses of UV coating?
UV coating is a versatile technology that can be applied to all types of paper products.
However, it works best with thicker, heavier papers such as rigid boxes and corrugated packaging.
UV coating plays an important role in enhancing artwork designs and making them truly come to life. This is why you are likely to see this finish applied to luxury packaging to add a sense of high quality.
