MFC as a Surface Coating for Barrier Performance

Background

MFC applied as a surface coating to moulded fiber 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 fiber 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 fiber-based packaging

Business Impact

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

Key Takeaway

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