Barrier coating solutions
Sustainable barrier coatings for paper, board & packaging
Retailers and brand owners are increasingly adopting overarching sustainability charters aimed at implementing responsible social and environmental practices across their business operations. Sourcing of packaging is one area that is being directly impacted by such initiatives, and is driving the demand for easily recyclable, mono-material packaging to replace more complex-to-recycle, multi-material packaging. As a consequence, there is a growing trend towards the replacement of fluorochemical treatments, polyethylene lamination, wax coating etc. with alternative barrier technologies that do not negatively impact the recyclability of the fibre-based packaging.
Working closely with leading brand owners and packaging converters, we have developed a range of ultra-platy minerals and ready-to-use, water-based barrier coating formulations for fibre-based packaging. Our coatings enhance the surface and functional quality of paper and board-based packaging and provide a more environmentally friendly alternative to the use of polyethylene, wax or fluorochemicals. Unlike these conventional solutions, our barrier coatings do not impact the recyclability of the fibre-based packaging and allow you to meet functional requirements in terms of barrier, overprint glueability and strength.
Our coatings also meet stringent surface quality requirements in terms of printability, smoothness, gloss, brightness and opacity.
Key application areas covered by our product portfolio
- Moisture vapour barrier
- Water barrier сoatings
- Oil & grease barrier coatings
- Mineral oil barrier
Customised coatings
In addition to a portfolio of “ready-to-use” coating solutions, we are also able to fine-tune our coatings to find the optimum combination of oleophobicity, hydrophobicity, moisture vapour barrier, printability, stiffness, opacity, machine runnability and economics in our formulation to match your specific requirements. Our custom-made coatings ensure optimised performance. Our technical experts can guide you in the choice of formulation and its application method.
