Printing aluminum foil on flexographic printing machines is a highly challenging process, but it combines the environmental advantages of flexographic printing with the functional advantages of aluminum foil.
The non absorbent, smooth surface, and stretchability of aluminum foil pose special requirements for flexographic printing.
The aluminium foil flexo printing machine uses specially designed UV-LED curing ink or water-based adhesive, which can instantly cure and firmly adhere to the surface of the aluminum foil.
Before printing, the aluminum foil must undergo corona treatment to increase its surface energy, allowing the ink to better wet and adhere.
Due to the easy stretching and deformation of aluminum foil, it is necessary for the printing machine to have a highly accurate tension control system to maintain stability throughout the entire process from unwinding to rewinding, ensuring accurate overprinting.
