DOLADISPLAY's plastic refrigerator tray collection represents the pinnacle of polymer engineering for cold storage applications. These high-performance trays utilize advanced copolymer blends optimized for low-temperature flexibility and impact resistance. The material science behind these products combines HDPE's durability with PP's chemical resistance, creating a hybrid formulation that outperforms standard foodservice plastics. Precision rotational molding ensures uniform wall thickness (3-5mm) with reinforced stress points at all high-wear areas. Special features include: anti-fog additives for clear viewing, static-dissipative compounds for electronic components, and FDA-compliant color masterbatches. The trays' structural design incorporates living hinges for divider components, snap-fit lid compatibility, and integrated labeling platforms. UV-stabilized versions resist degradation under display lighting, while conductive models prevent static buildup in sensitive environments. All plastic trays exceed ASTM D4101 standards for polypropylene materials.
