Paclan 60m Catering Aluminum Foil

The shiny side of aluminum foil holds heat better. If we don't want our dish to cool down too quickly, we should wrap it shiny side in. We do the same when baking dishes in the oven or on the grill.

On the other hand, the matte side of aluminum foil allows food to stay fresh longer. When preparing sandwiches for the road, we should roll them up so that the matte side is on the inside and the shiny side is on the outside. This way, we will limit the influx of warm temperatures, which means our sandwiches won't get warm or spoil. When putting food in the refrigerator, we should also cover it with the shiny side up, which will help it cool down faster.
