DOLADISPLAY's multipurpose refrigerator tray system delivers unmatched versatility for cold chain merchandising. These high-performance trays utilize cryogenic-grade polypropylene that maintains flexibility down to -40°C while resisting thermal deformation up to 90°C. The patent-pending lattice structure combines maximum strength (supporting 50kg distributed load) with optimal cold air circulation, reducing energy consumption by 15-20% compared to solid designs. Smart features include integrated condensation channels, anti-microbial silver ion additives, and color-changing temperature indicators in premium models. The universal corner geometry fits all major refrigeration equipment brands, with optional adapter kits for legacy systems. Specialized versions accommodate specific applications: perforated bases for deli displays, deep-well configurations for liquid containment, and subdivided layouts for portion control. The material formulation exceeds FDA and EU 10/2011 food contact requirements while remaining compatible with commercial dishwashers and steam sanitizing systems.
