The catering trays are just right for any table top dining. The G.E.T. Enterprises RCT16NS Plastic Non-Skid Serving Tray is made with polypropylene, which has a resistance to many chemical solvents, bases and acids keeping that clean, fresh look longer. The serving trays are also designed to have good resistance to fatigue. The practical round trays feature a solid brown color, and cork lined base. Also, the food trays are odor and stain resistant. In case of accidental bumps, the lip is raised in order to keep items from sliding off.
