Cambro was founded by two brothers, Bill and Argyle Campbell, in 1951, when Bill invented the Camtray and Argyle began selling the tray to the American Hospital Supply Corporation. The Camtray was quickly embraced by restaurant, hotel, school and cafeteria operators, and it became the industry standard. Growing from this heritage, today we offer the most complete line of sizes, shapes, colors and materials in foodservice trays. Bill's creativity was the impetus for new product development.Throughout the 1960's, Cambro introduced Camcover plate covers, drinkware, dinnerware and serving bowls to provide operators with long lasting tableware and serving items. Cambro also created the first plastic food pan and the first clear food storage container. By continuing to answer operators' storage needs, Cambro has developed the complete food storage solution to help operators ensure food is stored safe and fresh. This includes our recent innovations with our exclusive FlipLid, GripLid, and SlidingLid™.
