DOLADISPLAY's reusable refrigerator trays are engineered for sustainable cold storage solutions in commercial and retail environments. These high-performance trays utilize FDA-compliant polypropylene that withstands hundreds of wash cycles without warping or degradation. The reinforced rib structure provides exceptional load-bearing capacity (up to 25kg distributed weight) while maintaining flexibility at low temperatures. Smart design features include molded-in handles for easy transport, anti-slip corner pads to prevent shifting, and color-coded edges for inventory categorization. The material formulation resists stains from food pigments and prevents odor absorption - critical for multi-product use. Thermal-stabilized versions maintain dimensional accuracy across -30°F to 180°F temperature fluctuations. Specialized models incorporate micro-ventilation channels to optimize air circulation and condensation management. All trays meet NSF/ANSI 51 certification for food equipment and are dishwasher-safe up to 160°F. The eco-friendly construction contains 30% post-industrial recycled content without compromising hygiene standards.
