aluminum foil) is aluminium prepared in thin metal leaves. Approximately 75% of
aluminium foil is used for packaging of foods, cosmetics, and chemical products.When
aluminium foil is used for wrapping or cooking food, most people will struggle to choose which side of
aluminum foil sheet to use.Because of the manufacturing process, most of
aluminum foil roll is with one bright side and one matte side. There is only a small difference between the two, and there is not much difference in daily life.But if you really want to get a better effect, there are two tips for you. The reflectance of the dull side is 80% and that of the shiny side is 88%, so you had better use the shiny side to wrap food, which will speed up cooking.If you only store food in
aluminum foil, the better way is to use the dull side to wrap food for some food may stick to the shiny side.There is also another
aluminum foil paper, of which both sides are shiny. During single sheet rolling, the upper and lower surfaces of the
aluminum foil are in contact with the rolls, and both sides have a bright metallic luster. If you buy this
aluminium foil wrap, you won't have choice difficulties.
