When shopping for correctional meal trays, it's important to prioritize safety, durability, and ease of use. These trays are essential for serving meals in correctional facilities, and they need to be tamper-resistant and easy to clean to maintain a hygienic environment. Look for trays made of high-quality materials like polycarbonate or copolymer that are resistant to cracking, chipping, and shattering. Additionally, consider features like reinforced edges and corners, and tamper-resistant fasteners to minimize the risk of injury or contraband concealment. Choose trays that are stackable for easy storage and transportation, and select trays with dividers or compartments to prevent food from mixing.
