MFC Grinder Case Study: MFC in Moulded Fibre

MFC as a Surface Coating for Barrier Performance

Background

  • MFC applied as a surface coating to moulded fibre objects
  • Evaluation of grease, oxygen and aroma barrier properties
  • Assessment of MFC as a primer or pre-coat layer within multi-layer barrier coating systems

Trial Objectives

  • Improve grease resistance of moulded fibre packaging
  • Reduce oxygen transmission rates
  • Enhance aroma barrier performance
  • Evaluate MFC as a primer layer for additional barrier coatings

Trial Results

Trial Outcomes

  • MFC surface coating achieved grease resistance up to KIT 12
  • Significant reduction in oxygen transmission rate observed
  • Aroma barrier properties improved through MFC coating application
  • MFC demonstrated strong performance as a primer or pre-coat layer for additional barrier chemistries
  • Improved compatibility with multi-layer coating systems for fibre-based packaging

Business Impact

  • Supports development of PFAS-free moulded fibre packaging solutions
  • Reduces reliance on synthetic barrier materials
  • Enhances performance of recyclable fibre-based packaging
  • Enables improved barrier functionality using renewable fibre material

Key Takeaway

MFC surface coatings significantly improve grease, oxygen and aroma barrier performance in moulded fibre packaging while supporting PFAS-free barrier solutions.
