What material is the Corona Treater Roller made of?

There are two main materials for corona rollers: aluminum alloy and rubber.

In the plastic film packaging industry and double-stretch film (BOPP, BOPET, BOPI) industry, corona rollers are mainly processed by rubber rollers, and the rubber layer is mostly made of silica gel. The material of the corona roller can also be imported silica gel, with a hardness of 70-80A, ozone resistance, and high voltage resistance of 200,000 volts. In addition, there is a corona roller that is a high-precision functional roller made of high-purity alumina as the main material and processed by plasma spraying technology.

The advantages of corona rollers are very obvious. First, it can generate corona discharge on the surface of plastic films or papers, thereby increasing their surface tension and wettability, thus improving their printing and coating effects. Secondly, the surface of the corona roller is covered with a layer of polymer material, which can avoid the adhesion and contamination of ink or paint, thus improving the quality of printing and coating. In addition, the manufacturing process of corona rollers is relatively simple and the cost is relatively low, and it can be widely used in various printing and coating equipment.
