DOLADISPLAY's food grade refrigerator trays exceed global food safety standards with NSF, FDA, and EU 10/2011 compliant materials. These hygienic storage solutions utilize virgin-grade polymers free from BPA, phthalates, and heavy metal additives. The monolithic construction features radiused corners and seamless surfaces that eliminate bacterial harborage points - achieving <0.5 Ra surface roughness for optimal cleanability. Specialized formulations include USDA-approved pigments and UV stabilizers for color-fast performance under display lighting. Thermal properties maintain structural integrity from -40°F to 212°F, suitable for blast freezing to steam sanitizing cycles. Certification documentation includes full material traceability and migration test reports. Application-specific versions feature: perforated bases for produce airflow, anti-microbial embedded surfaces, and chemical-resistant compositions for cleaning product storage. All trays undergo rigorous QC testing including third-party verification of food contact safety.
