Converters Rapidly Adopt Certified PHA-Based Coating Formulations
Major paperboard and molded fiber converters pursuing PFAS-free positioning and recyclability certification are increasingly specifying certified PHA-based barrier coatings with documented compostability testing, rather than the fluorinated or conventional plastic laminate coatings that dominated the category when bio-based processing capacity was smaller in prior years. This shift commands meaningfully higher unit cost than conventional coatings given the added biopolymer feedstock and certification testing involved across most qualified formulators. Converters report certified PHA coating orders now outpacing conventional coating orders across several major packaging accounts tracked this cycle, a clear reversal from just a few years earlier. For a connected opportunity, MMA values the recycling-friendly water-based barrier coatings for fibre-based EU packaging market at USD 0.95 billion in 2025.
