Barrier Coating
The Quest for “Green” Products and Regulatory Strides
Sustainability has become a paramount concern for both personal well-being and the environment. In response to this heightened awareness, consumers are actively seeking environmentally conscious choices. Moreover, regulatory bodies are tightening their grip on packaging materials and waste management practices, amplifying the urgency for sustainable solutions.
In this dynamic landscape, the paper industry has taken a prominent role in the pursuit of renewable, eco-friendly packaging solutions. Emphasis has been placed on identifying suitable substrates, while chemical suppliers are innovating coating materials to enhance key properties.
Sustainable Barriers
A significant focus has been on the creation of sustainable paper and board barrier products. These innovations aim to replace conventional packaging solutions laden with plastics, perfluorocarbon, and wax. While water-based barrier coatings hold promise, they often come at a higher cost compared to traditional options. This has pushed for a dual focus on achieving competitive pricing and optimal performance by minimizing coat weight.
The successful deployment of barrier coatings hinges on precise application and meticulous metering. This process has a direct impact on the overall effectiveness of the barrier layer, influencing its ability to safeguard against various forms of penetration, including moisture, oxygen, fat, and mineral oil.
Layered Excellence: High-Performance Barriers
Research underscores the importance of constructing multiple coating layers to create high-performing barriers. These barriers are engineered to counteract diverse penetration challenges. Their intricate design makes them a crucial choice for applications where comprehensive protection is paramount.
Conversely, single-layer barrier products serve adequately in less demanding situations. They find application in scenarios such as fast-food wrapping paper, where a basic level of protection suffices.
