Barrier Paper Solutions

Increasingly, retailers and brand owners are 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 fibre-based packaging.

Working closely with leading brand owners and packaging converters, Imerys has developed a range of ready-to-use, water-based barrier coating solutions for fibre-based packaging. Our coatings enhance the surface and functional quality of paper & 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 fibre-based packaging, and allow meeting functional requirements in terms of

  • barrier
  • over print
  • glueability
  • strength

Our coatings also allow meet stringent surface quality requirements in terms of:

  • printability
  • smoothness
  • gloss
  • brightness, and
  • opacity

Key application areas covered by our product portfolio are

  • Moisture Vapor barrier
  • Oil & Grease barrier
  • Water barrier and
  • Mineral Oil barrier

The portfolio also covers non-barrier coating formulations for printability of corrugated board (precoat primers and white coatings).
