Commodity Shippers Rapidly Adopt Barrier Liner Formats
Commodity exporters shipping moisture-sensitive cargo across major dry bulk trade lanes are increasingly specifying barrier multi-layer container liners with documented moisture-barrier and contamination-protection testing, rather than the conventional woven polypropylene liner that dominated dry bulk shipping when barrier film reliability was less proven in prior years. This shift commands meaningfully higher unit cost than conventional woven format given the enhanced film lamination and testing requirements involved. Converters report barrier orders now outpacing woven orders across several major commodity shipper accounts tracked this cycle, a clear reversal from just a few years earlier. This dynamic also shapes the inner bulk liners market, valued by MMA at USD 2.1 billion in 2025 and expected to reach USD 4.07 billion by 2036.
