Mono-Material Molded Trays Reach Mainstream Regional Retailers
Recyclable mono-material molded paperboard trays, which use an engineered single-ply fiber molding structure intended to maximize recyclability and food contact safety across a continuously varying bento box mix rather than relying on conventional polystyrene dependent architecture alone, have moved from niche premium flagship convenience store majors into mainstream regional supermarket accounts since 2023 as mono-material production costs declined enough to reach smaller regional operations nationwide overall. This documented recyclability advantage addresses genuine material use concerns conventional polystyrene stock alone could never satisfy. Retailers now require certified recyclability ratings for renewal programs. Much of this also feeds into the paperboard jewellery box market, which MMA expects to grow at 6.8% a year through 2036.
