Barrier Coating Solutions

BARRIER COATING MINERALS & FORMULATIONS Environment-friendly barrier coating solutions for the food and non-food segments of the fiber-based packaging industry

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 replacement of fluorochemical treatments, polyethylene lamination, wax coating etc. with alternative barrier technologies that do not negatively impact recyclability of the fiber-based packaging.

Working closely with leading brand owners and packaging converters, Imerys has developed a range of ultra-platy minerals and ready-to-use, water-based barrier coating formulations for fiber-based packaging. Our coatings enhance the surface and functional quality of paper and board based packaging and provide a more environmentally-friendly alternative to use of polyethylene, wax, or fluorochemicals. Unlike these conventional solutions, our barrier coatings do not impact the recyclability of the fiber-based packaging, and allow meeting 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

Customized 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 vapor barrier, printability, stiffness, opacity, machine runnability and economics in our formulation to match your specific requirements! Our custom-made coatings ensure optimized performance. Our technical experts can guide you in the choice of formulation and its application method.
