The food pan cover can have a closed top end having a first top edge and a second top edge and an open bottom end having a first bottom edge and a second bottom edge. A first side seal extends from the top end to the bottom end, and a second side seal extends from the top end to the bottom end. A gusset can be formed between the first top edge and the second top edge. The food pan cover can be formed from a single layer of heat-shrinkable polymeric material capable of withstanding a temperature of at least about 400 degrees Fahrenheit.
