DOLADISPLAY's freezer safe refrigerator trays are engineered for seamless transition between refrigeration and deep freeze environments. These cryogenic-performance trays utilize specialty polymers that maintain flexibility at -94°F while resisting thermal shock fractures. The patented lattice structure prevents brittle failure points through distributed stress design. Testing verifies 500+ freeze-thaw cycles without material degradation (per ASTM D6662). Non-stick surfaces prevent product adhesion even at ultra-low temperatures, while raised edges contain frost accumulation. Applications include: flash freezing operations (with quick-release features), long-term frozen storage (stackable to 15 high), and temperature transition zones (dual-zone material formulation). The bright white color enhances visibility in frost-filled environments, and embossed temperature indicators confirm safe operating ranges. All freezer trays meet USDA and CFIA standards for frozen food handling and are backed by a 5-year thermal performance guarantee.
