Manufacturing Principle Of Electrochemical Aluminum

For foil stamping, the most important auxiliary material is foil stamping paper, which is what we call electrochemical aluminum. The types of electrochemical aluminum are roughly divided into ordinary and laser, and laser is divided into plain surface and flower plate. The properties of various types of electrochemical aluminum are different. Some of the same type but different batches will change their comprehensive properties.

（1） Anodized aluminum is usually based on PET film; The bottom layer is stripper and color coating, the middle layer is a vacuum jet decomposition aluminum powder layer, and the surface layer is adhesive (hot sol). As shown in the figure:

1. Laser Anodized Aluminum: the film material is pet, and the film thickness is 14-18 μ， Laser anodized aluminum is beautiful, bright and colorful. Its applicable temperature is 110 ℃ -150 ℃. In addition, laser holographic positioning ironing is mainly used for cigarette labels, wine boxes, cosmetics packaging, etc. it is the most popular anti-counterfeiting method in the bronzing industry. The applicable temperature is 110 ℃ -150 ℃.

2. Ordinary Anodized Aluminum. The material is PEF. There are many films with a thickness of 12-14 μ， There are gold, red, copper, blue, black and other colors, and the applicable temperature is between 90 ℃ -120 ℃.
