Meal-Kit Shippers Rapidly Adopt Certified Mono-Material Liners
Major meal-kit and grocery delivery shippers pursuing curbside recyclability compliance and reduced sorting facility rejection exposure are increasingly specifying certified mono-material thermal liners with documented thermal performance validation, rather than the conventional multi-layer foam liners that dominated the category when certified mono-material capacity was smaller in prior years. This shift commands meaningfully higher unit cost than conventional multi-layer foam given the added insulation engineering and testing involved across most qualified converters tracked. Shippers report certified mono-material orders now outpacing conventional foam orders across several major delivery categories tracked this cycle, a clear reversal from just a few years earlier. Adjacent demand is captured in the insulated thermal box liners market, which MMA expects to grow from USD 2.6 billion in 2025 to USD 6.64 billion by 2036.
Market Impact: Drives roughly 8% of demand
