Characteristics of aluminum foil
Today aluminum coil manufacturer GNEE Aluminum will take you through the characteristics of aluminum foil.
As the packaged items are fully blocked from external light, moisture and gas, thus the packaging is well maintained. Especially for the packaging of steamed food, the use of this composite aluminum foil material can ensure that the food does not deteriorate for at least one year. Moreover, it is very convenient to heat and open the package, which is popular among customers. The general thickness of packaging aluminum foil is between 0.03mm and 0.1mm.
Aluminum foil has clean, hygienic and shiny appearance, it can be made into integrated packaging materials with many other packaging materials, and the printing effect of aluminum foil appearance is better than other materials, in addition to the following characteristics of aluminum foil:
(1) The appearance of aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can grow on its appearance.
(2) Aluminum foil is a non-toxic packaging material, which can be directly touched with food without any worry of harming human health.

2、It has an elegant silver-white luster and is easy to process with beautiful patterns and designs in various colors;
3、After aluminum foil is laminated with plastic and paper, the shielding property of aluminum foil is integrated with the strength of paper and heat sealing property of plastic, which further improves the shielding property of aluminum foil tape as a packaging material necessary for water vapor, air, ultraviolet light and bacteria, etc., and greatly broadens the application market of aluminum foil.
