Alloy 8011 and 8021 colored aluminum foils are two popular color coated aluminum foil in packaging. What is the aluminum foil’s color coating process? What should an aluminum foil manufacturer stress? Learn more.

In recent years, the scope of application of aluminum foil packaging has continued to expand. In addition to pharmaceutical packaging, it is also used in food packaging, health care product packaging, etc., which has prompted the market of the colored aluminum foil. We no only have colored aluminum foil with one color like gold aluminum foil, but also has multi-color varieties with colorful text patterns. Alloy 8011 color coated aluminum foil is very popular.

Aluminum foil printing is to print text patterns through the concave surface of the printing plate roller. Firstly, the printing plate roller is processed is processed to obtain the printing plate graphics and text. The graphics and text parts are corroded into ink holes or pits on the surface of the roller's copper layer, while the non-graphic and text parts are the outer copper surface of the roller itself.

Then, the printing plate roller rotates in the ink tank, filling each ink hole with thin ink. When the roller rotates and spins out of the ink tank, the excess ink on it is removed by the scraper installed on the surface of the printing plate roller.

Finally, when the printing plate roller comes into contact with the aluminum foil as the substrate, the elastic rubber impression roller presses the aluminum foil surface against the printing plate roller, causing the ink in the ink holes to transfer to the aluminum foil surface. At this time, the aluminum foil printing work is completed.

Since aluminum foil is different from paper and plastics, the key to its printing applicability is to master the ink characteristics, ink viscosity and ink dryness in order to print products that meet quality standards and meet user satisfaction.

If you want to get the correct color required by the user, you must grasp the coating amount of adhesive and protective agent during the process. This is a very important process indicator. If the adhesive protective agent is incorrectly configured, the coating amount is greatly different, or the process operation is not standardized, it may cause uneven color and different shades of aluminum foil after coating, and poor adhesion to the plastic hard sheet, thus causing problems in the coating process.

It not only affects the appearance quality of the product, but also affects the intrinsic quality of the product. Haomei Aluminum is an experienced aluminum foil manufacturer. We can provide rich alloys of colored aluminum alloys like 8011 and 8021 aluminum foil paper.
