Retailers Rapidly Adopt Certified Compostable Punnet Formats
Retailers pursuing sustainability positioning and regulatory compliance are increasingly specifying certified compostable punnets with documented biodegradability testing and fiber-sourcing certification, rather than the conventional plastic clamshell that dominated the category when compostable tooling costs were less competitive in prior retail cycles. This shift commands meaningfully higher unit cost than conventional clamshells given the enhanced forming and certification testing involved across most qualified suppliers. Manufacturers report compostable punnet orders now outpacing conventional plastic orders across several major retail accounts tracked this cycle, a clear reversal from just a few years earlier across the broader sector.
Market Impact: Drives roughly 4% of demand
