Brands Rapidly Adopt Mill-Validated High-Barrier Chemistry
Pharmaceutical brands facing moisture-sensitive formulation requirements are increasingly specifying validated high-barrier monomaterial PET with documented moisture and oxygen testing, rather than the conventional multi-layer laminate that dominated blister construction when barrier requirements were less stringent in prior years. This shift commands meaningfully higher material cost than conventional multi-layer laminate given the enhanced validation and testing requirements involved. Suppliers report high-barrier orders now outpacing conventional laminate orders across several major brand accounts tracked this cycle, a clear reversal from just a few years earlier across the category broadly. Several converters are investing specifically to meet this validation standard. Linked demand sits in the molded fiber blister packs market, projected by MMA to reach USD 1.61 billion by 2036 on a 15.2% CAGR.
Market Impact: Drives roughly 6% of demand
