Retail Chains Rapidly Adopt Certified Multi-Compartment Tray Formats
Major UK and European retail chains pursuing plastic-free positioning and reduced CPET liability exposure are increasingly specifying certified multi-compartment compostable trays with documented heat performance testing, rather than the conventional single-compartment CPET formats that dominated the category when ready-meal portfolios were smaller in prior years. This shift commands meaningfully higher unit cost than conventional CPET given the added molding complexity and certification testing involved across most qualified converters. Chains report certified multi-compartment orders now outpacing conventional CPET orders across several major retail accounts tracked this cycle, a clear reversal from just a few years earlier. Linked demand sits in the biodegradable stretch films market, projected by MMA to reach USD 2.39 billion by 2036 on an 8.8% CAGR.
Market Impact: Drives roughly 6% of demand
