Aqueous-Based Barrier Coating

Aqueous-Based Barrier Coatings

Aqueous-Based Barrier Coatings are advanced water-based coating technologies designed to provide moisture, grease, oil and surface protection for sustainable paper and packaging applications. Developed as environmentally conscious alternatives to traditional plastic laminates and solvent-based coatings, these specialist barrier systems help improve packaging functionality whilst supporting recyclability and sustainability goals.

Widely used across food packaging, paperboard cartons, takeaway packaging and flexible packaging applications, these barrier coatings create a protective functional layer that enhances durability and resistance without compromising modern environmentally responsible packaging requirements. Suitable for flexographic, gravure and industrial coating systems, these water-based coatings combine strong packaging performance with efficient high-speed converting compatibility.

What are Aqueous-Based Barrier Coatings?

Aqueous barrier coatings are water-based polymer coating systems applied to paper, board and packaging substrates to create protective functional barriers against moisture, grease, oils, oxygen and handling wear. Unlike traditional plastic film laminates, aqueous coatings form a thin protective polymer layer directly on the substrate surface without requiring separate plastic film structures.

These coatings are typically formulated using water-borne acrylics, polyurethane dispersions, PVOH or specialist polymer blends engineered to provide packaging protection whilst supporting improved recyclability and sustainability performance.

Aqueous barrier coatings are increasingly used as alternatives to polyethylene (PE) extrusion coatings and solvent-based systems because they:

• reduce plastic usage
• support recyclable packaging
• lower VOC emissions
• improve sustainability profiles
• maintain packaging functionality

This makes them highly suitable for modern, environmentally conscious packaging production.
