Covers for food service pans
A heat-shrinkable polymeric cover provides a safe, low cost way to cover a food service pan during food preparation, storage, cooking, transport and reheating. 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.
1. A food pan cover comprising:
a closed top end comprising a first top edge and a second top edge;
an open bottom end comprising a first bottom edge and a second bottom edge;
a first side seal extending from the top end to the bottom end;
a second side seal extending from the top end to the bottom end;
a first lateral wall formed by the first top edge, first bottom edge, first side seal, and second side seal;
a second lateral wall formed by the second top edge, second bottom edge, first side seal, and second side seal; and
a gusset formed between the first top edge and the second top edge,
wherein the food pan cover is formed from a heat-shrinkable polymeric material capable of withstanding a temperature of at least about 400 degrees Fahrenheit for at least about two hours.
2. The food pan cover of claim 1 , wherein the food pan cover is sized to fit about a Gastronorm pan.
3. The food pan cover of claim 1 , wherein the polymeric material is substantially Clear.
4. The food pan cover of claim 1 , wherein the gusset comprises:
a first top panel bounded by the first top edge and a longitudinal fold line; and
a second top panel bounded by the second top edge and the fold line.
5. The food pan cover of claim 4 , wherein the gusset expands to increase a distance between the first lateral wall and the second lateral wall.
6. The food pan cover of claim 4 , wherein the first top panel is approximately equal in size to the first lateral wall and the second top panel is approximately equal in size to the second lateral wall.
7. The food pan cover of claim 1 , further comprising:
a first angled seal extending from the first side seal to the first top edge; and
a second angled seal extending from the second side seal to the first top edge.
8. The food pan cover of claim 7 , further comprising:
a third angled seal extending from the first side seal to the second top edge; and
a fourth angled seal extending from the second side seal to the second top edge.
9. The food pan cover of claim 8 , wherein the heat-shrinkable polymeric material comprises a mono-layer film having a thickness in the range of about 0.8 mils to about 1.5 mils.
10. The food pan cover of claim 9 , wherein the heat-shrinkable polymeric material is a mono-layer film having a thickness of about one mil.
11. The food pan cover of claim 10 , wherein the mono-layer film comprises polyester and a polyester elastomer.
12. The food pan cover of claim 8 , wherein the heat-shrinkable polymeric material comprises a multi-layer film having a thickness in the range of about 0.8 mils to about 1.5 mils.
