Delivery Operators Rapidly Adopt Validated Clamshell Formats
Delivery operators pursuing transit containment and leak resistance are increasingly specifying validated foamed plastic clamshells with documented seal integrity and insulation testing, rather than the conventional tray that dominated the category when specialty clamshell tooling costs were less competitive in prior years. This shift commands meaningfully higher unit cost than conventional format given the enhanced testing and certification requirements involved. Manufacturers report clamshell orders now outpacing tray orders across several major delivery operator accounts tracked this cycle, a clear reversal from just a few years earlier across the sector. This trend shows no signs of slowing anytime soon.
Market Impact: Drives roughly 4% of demand
