DOLADISPLAY's reusable supermarket refrigerator trays are designed for sustainable long-term use across thousands of product cycles. Manufactured from FDA-compliant polypropylene with 30% glass fiber reinforcement, these trays endure commercial dishwashing at 85°C without degradation. The one-piece rotational molding process eliminates seams where bacteria could accumulate, while rounded corners facilitate thorough cleaning. Color-coded versions (available in 6 standard colors) enable department-specific identification and streamline inventory management. The trays' nestable design reduces storage space by 60% when not in use, and integrated stacking lips prevent jamming during transport. Special wear indicators along high-friction edges alert staff when trays need rotation out of service.
