The surface of aluminum foil is evenly coated with glue, lacquer, wax, pigment, or paint with some special functions. After drying or solidification, it can be firmly combined with the aluminum foil is called aluminum foil coating.
All aluminum foil, whether it is plain foil or composite foil, in hard state or soft state, with one side or two sides, can be coated. According to different coating materials, various types of aluminum foils with different properties can be obtained, such as brightly colored dyed foils and medicinal foils with thermal bonding properties. In order to obtain water resistance, frost resistance, abrasion resistance, oil resistance, acid resistance, alkali resistance, insulation, anti-slip properties, etc., it can be coated with corresponding substances to improve the properties of aluminum foil.
According to different coating types and product requirements, there are many processes for aluminum foil coating processing.
