64 CHEMICALS KNOWLEDGE HUB Issue 1 / July 2025 Water-based barrier coatings are liquid coatings that, once dried, create a protective layer on materials like paper and cardboard, resisting moisture, grease, and oil. They are a sustainable alternative to traditional plastic coatings, promoting recyclability and composability. These coatings are commonly used in packaging for food and beverages, as well as in other applications where moisture resistance is crucial. According to MarketsandMarkets the global waterbased barrier coatings market size is projected to reach USD 1.85 billion by 2030 from USD 1.28 billion in 2024, at a CAGR of 6.3% between 2025 and 2030. Water-based barrier coatings are increasingly utilized in the packaging sector, specifically for food containers, beverage cartons, wrappers, and industrial packaging films. These coatings provide essential protection against moisture, oil, grease, and gases, enhancing the sustainability and ease of disposal of packaging materials. Engineered to withstand frequent use, fluctuations in humidity, and temperature variations, these coatings maintain their effectiveness over time. The growing emphasis on safe, environmentally friendly packaging and stringent regulations concerning food safety and environmental impact is driving adoption across various industries. Recent advancements in coating technology are significantly enhancing both these products’ protective capabilities and sustainability, further supporting market expansion. Additionally, the rapid industrialization and rising demand in food processing and e-commerce sectors worldwide are contributing to the increasing demand for water-based barrier coatings. The demand for water vapor barrier coating products is expected to increase significantly over the forecast period, driven by their critical role in protecting moisture-sensitive products. As global consumption of packaged food, pharmaceuticals, and personal care products rises, the need for effective moisture-resistant packaging solutions is paramount to preserving product integrity and ensuring safety. Water-based coatings that offer water vapor barriers present a more environmentally sustainable alternative compared to traditional plastic laminates and aluminum foils, aligning with regulatory requirements and market expectations. The emphasis on compostable, recyclable materials devoid of PFAS (per- and polyfluoroalkyl substances) further underscores the growing importance of water vapor barrier coatings in the packaging industry. Additionally, nano-coating and bio-based technologies enhance packaging performance without compromising sustainability. As industries shift their focus toward utility and eco-friendly solutions, water vapor barrier coating MATERIAL SCIENCE
