Understanding Aqueous Paper and Its Benefits
Aqueous paper refers to paper products that have been coated with a sustainable, non-toxic aqueous solution. This water-based coating is used to improve the durability and appearance of the paper, making it a popular choice in printing and packaging industries. Here’s a handy breakdown of what aqueous paper is, its benefits, and how it compares to other types of coatings.
Types of Aqueous Coatings
Aqueous coatings come in various types, each offering unique benefits:
- Gloss Coating: Provides a shiny finish that enhances colours and protects against smudges and scuffs.
- Matte Coating: Reduces glossiness for a more muted effect while still offering protection.
- Satin Coating: Offers a balance between gloss and matte finishes, providing good protection and a slight sheen.
- Dry Erase Coating: Allows the surface to be used like a whiteboard, suitable for applications requiring frequent updates.
- Pencil Receptive Coating: Suitable for products that need to be written on with pencils or ink.
- Soft Touch Coating: Gives the paper a velvety texture, enhancing the tactile experience (Refine Packaging) (Color Vision Printing).
Why Aqueous paper is a great choice for food packaging
- Food Safety and Compliance
Aqueous coatings are designed to meet food safety standards, making them suitable for direct contact with food. - Barrier Properties
Aqueous coatings provide a barrier against moisture and grease, essential for maintaining the integrity of food packaging. This prevents the package from becoming soggy or greasy, ensuring the food remains fresh and safe to eat (Verive) (packaginginsights.com). - Recyclability and Biodegradability
Unlike traditional plastic coatings, aqueous coatings are more environmentally friendly. They can be recycled in standard paper recycling streams and are often biodegradable, reducing the environmental impact of packaging waste. - Durability: Aqueous coatings offer excellent protection against scuffing, scratching, and handling, which is crucial for food packaging that needs to maintain its integrity from production to consumption (Color Vision Printing)(PrintSouth).
Environmental Impact
A key advantage of aqueous coatings is their environmental friendliness. Being water-based, they are less harmful during application and disposal compared to solvent-based coatings like UV coatings. It's possible to use an aqueous dispersion layer to create recyclable and biodegradable paper cups, which helps reduce plastic waste.
Application and Use
Aqueous coatings are applied before the ink in the printing process and dried quickly to prevent warping or curling of the paper. This coating provides a protective layer that is especially useful for printed materials that undergo a lot of handling, such as custom-branded food packaging, postcards, and business cards (Color Vision Printing) (PrintSouth).
Comparing Aqueous Coatings to Other Coatings
Aqueous coatings differ from other types of coating, like UV coatings for example, primarily in their drying process and environmental impact. While UV coatings cure under ultraviolet light and offer a high-gloss finish, they involve non-volatile compounds that can be less eco-friendly.
In contrast, aqueous coatings dry through evaporation or absorption into the paper, making them a more sustainable option (Refine Packaging) (PrintSouth).
