What Is An Aqueous Coating?Aqueous coatings are use in all industries, not just food contact. They can be applied to various substrates like paperboard, plastic, aluminum foil, and more. It is a thin (approximately 10 microns) liquid layer made partially of water. That means the physical properties aren’t consistent. They are thin enough to be breathable (allowing the product to “breathe”). Still, they provide an extra barrier against outside contaminants like dirt, moisture, and dust. Read more about UV Coating. Aqueous coatings are considered water-based because of their thin makeup of water. Most coatings used today are aqueous because of their ease of use, environmentally friendly properties, and cost-effectiveness.
How Do Aqueous Coatings Work?Because the aqueous coating is applied as a liquid, it’s straightforward to see how this process works. Two rolls are use that applies two separate layers of liquid on top of each other. The first roll applies the aqueous coating, while the second roll removes any excess coating. Depending on your needs, that can be done in one or two machines. Then the sheets pass through a quick drying process. The result is a protective, breathable layer with outstanding durability. It is important to use paperweights or other ways to ensure that the sheet remains flat and doesn’t shrink or wrap as it is being dried.
Types Of Aqueous CoatingMany different types of aqueous coatings offer varying levels of gloss and texture. For example, a matte coating would be dull and non-reflective, while a gloss coating would be shiny and reflective. The most common types of coatings for custom packaging are:
Matte FinishA combination of high opacities (the ability to block light) and good whiteness makes this an ideal choice for packaging that you want to highlight.
Gloss FinishThis coating offers a high-gloss look with the opportunity to create bright, vibrant colors and images on your packaging.
Satin FinishThe satin finish is a cross between matte and gloss finishes that create a beautiful luminescent color that catches the light without being too shiny or reflective.
Soft-Touch FinishThe soft-touch coating creates a tactile, velvety surface that offers the look of leather or suede. It is excellent for showcasing product images on your packaging.
Pencil Receptive FinishThis is very similar to the soft-touch finish, but it also works well with pencils and other writing utensils.
Dry Erase FinishThis finish is excellent for custom packaging used for promotional events or educational purposes because you can easily use a dry erase marker on this surface.
The Benefits Of Aqueous CoatingThere are many benefits to using an aqueous coating on your custom packaging, which include:
Water-BasedYour packaging can be made from recycle content and non-toxic materials, making it environmentally friendly. The aqueous coating contains water as its base ingredient.
Durable FinishAqueous coatings provide an extra barrier against outside contaminants like dirt, moisture, and dust. It is also scratch-resistant & heat-resistant. This coating is strong enough to stand against the wear and tear that stacks the paper face during shipping, handling, and storage.
CustomizableMany packaging companies offer various options for you to choose from, including materials, finishes, colors, and sizes. You can quickly get exactly what you need for your needs and specifications.
Sealed FinishAqueous coating provides a protective, water-resistant finish on the product’s packaging. It forms a thin film of protection that adds durability to the product and gives it an extra layer of security against moisture and other contaminants.
Cost-EffectiveAqueous coatings are very cost-effective options that also protect against the elements. It can be use with recycled materials and other eco-friendly components.
Environmentally FriendlyThe coating is water base, making it safe for the environment and easy to dispose of. In addition, this method entails no air pollution, which makes it the greenest option for custom packaging. The water-based formula also reduces VOCs (volatile organic compounds) to less than 25% of what is require by FDA regulations.

- No harmful fumes or gases that pollute the environment
- Reduced VOC levels and odors
- Better printability than other coating options
- Increased opacity and coverage that prevents see-through images or colors
- Readily available materials and environmentally friendly base ingredients
- No impact to the environment during production, use, and disposal
