New Metallized Film Demetallizing Machines

The demetalizing machine is special equipment designed for following usage:

• Decorative labels and stickers

• Holographic security labels

• Transparent windows in flexible packaging

• Anti-counterfeiting marks

• Electrical insulation with selective conductivity

Our machines operate at speeds ranging from 30 to 150 meters per minute, depending on:

• Film width and thickness

• Pattern complexity

• Chemical formulation and drying capacity

• For pure Al foil de-metalizing,it will be needed multi chemical tanks and chemical concentration, the speed will be slower and depends on the thickness of Al foil.

Leading suppliers include manufacturers in China Kingsun, Italy, Germany. Kingsun specialized in customized solutions for packaging and security printing industries, demetalizing machine exported to Europe, USA and many other countries with 25 years experience.

The demetalizing machine, also called as aluminum washing machine, it is a chemical processing system used to selectively remove the aluminum coating from metallized films (such as PET, OPP, or PVC) to create designs, patterns, or transparent windows, it is special application for high level flexible packaging, RFID or anti-counterfeit use. This process is also known as chemical de-metallization or aluminum etching.

The machine applies a chemical solution (usually sodium hydroxide/NaOH or a proprietary alkaline etchant) through a printing or coating process. The chemical reacts with the aluminum layer, dissolving it and leaving behind a transparent area. The film is then washed, neutralized, dried, and rewound.
