Biologics-Adjacent Converters Rapidly Adopt Validated COC Formats
Biologics-adjacent converters pursuing moisture barrier performance and product stability are increasingly specifying validated cyclic olefin copolymer resins with documented water vapor transmission and extractable-leachable testing, rather than the conventional pharma-grade PET that dominated the category when cyclic olefin copolymer tooling costs were less competitive in prior years. This shift commands meaningfully higher unit cost than conventional grade given the enhanced testing and certification requirements involved. Resin producers report cyclic olefin copolymer orders now outpacing PET orders across several major converter accounts tracked this cycle, a clear reversal from just a few years earlier across the sector. The pharma blister packaging market moves on similar drivers, with MMA projecting a 6.8% CAGR over 2026-2036.
Market Impact: Drives roughly 4% of demand
