Fractional pans are used primarily to hold ingredients in a sandwich or salad table. The pans are usually left open, so workers can easily access the requested ingredients. At the end of the day, the pans are usually covered with foil or saran wrap. This method is quick but expensive, because the wrap is thrown away in the morning, and you are constantly buying new rolls. As a more economical, and eco-friendly, alternative, cover your sixth-pans with a Cambro One-Sixth Size Cover w/ Handle (60PPCH). The cover can be washed and reused over and over, eliminating the need for purchasing rolls of disposable wrap.
