Seafood Exporters Rapidly Adopt Validated Moisture Formats
Seafood exporters pursuing wet-strength reliability and export shipping durability are increasingly specifying validated wax-coated boxes with documented coating application and compression testing, rather than the conventional unwaxed carton that dominated seafood shipping when wax tooling costs were less competitive in prior years. This shift commands meaningfully higher unit cost than conventional carton format given the enhanced testing and certification requirements involved. Converters report wax box orders now outpacing unwaxed orders across several major seafood exporter accounts tracked this cycle, a clear reversal from just a few years earlier across comparable shipments. Adjacent demand is captured in the membrane boxes market, which MMA expects to grow from USD 2.3 billion in 2025 to USD 4.55 billion by 2036.
