Shippers Quickly Standardize on Compostable Liner Formats
Cold-chain shippers facing tightening state and municipal plastic restriction rules are increasingly specifying compostable moisture-barrier liner paper with documented certification testing, rather than the conventional plastic-coated liner that dominated cold-chain shipping when plastic restriction scrutiny was less stringent in prior years. This shift commands meaningfully higher material cost than conventional plastic-coated liners given the enhanced certification requirements involved. Suppliers report compostable orders now outpacing plastic-coated orders across several major shipper accounts tracked this cycle, a clear reversal from just a few years earlier across the category broadly. This reversal is prompting several converters to rethink their format mix entirely. MMA tracks this demand in the grease-resistant paper liners market, which it projects to grow at 5.4% a year through 2036.
