Paclan 40m Catering Aluminum Foil

The glossy side of the aluminum foil holds heat better. If you don't want your food to cool down too quickly, you should wrap it in the shiny side from the inside. We do the same when baking food in the oven or on the grill.

On the other hand , the matte side of aluminum foil allows food to stay fresh for 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 on the outside. In this way, we will limit the supply of warm temperature, so that our sandwiches do not heat up or spoil. When putting food in the refrigerator, we should also cover it with the shiny side up, which will make it cool faster.
