BOPET Production Line Corona Roller Synthetic Rubber Coated Used Corona Treater
Corona Roller Basis Information
Silicone rubber coated corona roller is a type of roller used in corona treatment processes for films. It is designed to enhance the surface properties of polymeric films, such as polyethylene films, by subjecting them to a corona discharge. The corona discharge helps improve the film's ink retention, coating adhesion, and printability.
The principle is to use a high frequency and high voltage corona discharge on the surface of the treated plastic (high frequency AC voltage up to 5000-15000V/m2), and produce a low temperature plasma, so that the plastic surface produces a free group reaction and the polymer cross-linked. Roughness of the surface and increase its wettability to polar solvents - these ionoplasms destroy their molecular structure by electric shock and penetration into the surface of the printed body, which in turn oxidizes and polarizes the treated surface molecules, and ionic electric shocks erode the surface, resulting in increased adhesion of the substrate surface.
The purpose of corona treatment is to change the surface energy of many substrates so that they are easily bonded to printing inks, coating materials and adhesives. All substrates have good adhesive properties after some treatment during the manufacturing process. Corona treatment is a post-processing, it should be pointed out that corona treatment is not a process that can be used to change the surface energy of the substrate when producing the substrate. Other treatment methods include flame treatment and coating treatment. Which treatment method is used mainly depends on the structure of the substrate.
Corona Roller Advantage

Our corona rollers rubber roller are industry leading in both silicone and ceramic treater applications. With 100% spark testing prior to shipment you are ensured the highest quality and longest lasting corona roller rubber roller in the market.
Silicone rubber is a popular choice for Corona Rollers due to its relatively low cost and ease of replacement in the field.
It provides a smooth and uniform surface for the film to pass over during the corona treatment process.
Silicone rubber coatings have good dielectric properties, allowing for efficient corona discharge and treatment of the film.
