The Short Version
Fresh food holds up best at an even temperature. Plastic pans insulate rather than conduct cold, and a pan that fits correctly keeps the case’s airflow working. Worn, warped or cracked pans undo both.
When a refrigerated case is running right, cold air moves in a set loop from the coils, across the product and back again. The pans that sit on the deck are part of that system. Their material and their condition both affect how evenly the food stays cold.
Plastic Insulates, Metal Conducts
Metal pulls cold quickly and passes it straight into whatever is sitting on it. That can create cold spots where delicate items freeze or dry out, while other areas run warmer.
Plastic works differently. It acts as a mild insulator, so it doesn’t transfer cold as aggressively. The result is a more stable, even temperature around the product.
■Meat holds its color and texture longer without frozen edges.
■Deli salads and cheese stay consistent instead of drying out along the pan.
■Produce, especially leafy greens, is protected from localized freezing.
Fit Matters as Much as Material
Even the right material can’t help if the pan doesn’t seat correctly. Over time, pans crack, chip, warp or sag. A pan that sits unevenly can block or redirect the case’s airflow, leaving warm zones where product spoils faster.
A new, precise-fit pan sits flat in its slot and keeps the designed airflow path intact, which helps the whole case hold a steady temperature.
Why Even Temperature Pays Off
■Safer holding temps. Cold foods generally need to stay at 41°F or below. Even cooling helps every part of the case stay there.
■Less shrink. Product that stays at a steady temperature keeps its quality longer, so less gets marked down or thrown out.
■Less strain on equipment. When the case isn’t fighting uneven temperatures, the refrigeration system doesn’t have to work as hard.
The Bottom Line
Pans are one of the simplest parts of a refrigerated case to replace, and one of the easiest to overlook. Swapping worn pans for new, precise-fit plastic ones helps keep temperatures even, protects product quality and keeps the case working the way it was designed.
