Coated aluminum foil is a process in which other materials are coated on the surface of aluminum foil to change its properties and uses. The coated aluminum foil processing technology mainly includes material preparation, surface treatment, coating, drying and coiling.
First, prepare materials. Choose high-quality aluminum foil as the base material, and determine the materials that need to be coated according to different usage requirements, which usually include polymer resins, coating agents and other additives.
Secondly, carry out surface treatment. The surface of the aluminum foil needs to be degreased, deoxidized and roughened to ensure that the coating can adhere firmly to the surface of the aluminum foil and provide better coverage and adhesion.
Next, proceed to the coating operation. The pre-prepared coating material is usually evenly coated on the surface of the aluminum foil using roller coating, blade coating or spray coating to form the required functional coating. During the coating process, parameters such as coating speed, coating thickness, temperature and humidity need to be controlled to ensure the quality and uniformity of the coating.

Then, drying is performed. After the coating is completed, it needs to be dried to remove the solvent in the coating and ensure that the coating can be fully cured and firmly bonded to the aluminum foil surface. Usually an oven or drying chamber is used for heat treatment, and ultraviolet curing technology can also be used for rapid curing.
Finally, take up the coil. The dried coated foil is rolled into rolls or cut into sheets. After packaging and quality inspection, it can be put into the market.
The coating aluminium foil processing technology has certain technical difficulties and production requirements, and each link needs to be strictly controlled to ensure the uniformity, adhesion and durability of the coating. At the same time, in response to different needs, the coating formula and process parameters also need to be optimized to meet the use requirements in different fields.
