Add More Flair to Your School Trays With This One Simple Trick Not only does a compartment tray display food in an organized manner โ and keep peas from mixing with mashed potatoes โ but did you know that it can display your school pride, too? You can add your school logo, mascot or other symbol to any compartment tray in any color. According to Cafeteria Culture, a nonprofit that advocates for creating zero waste school foodservice operations, the ideal solution for school trays are reusable ones, like the Cambro School Compartment Trays. Personalized with your school logo, these trays make a great alternative to disposable, styrofoam trays.
