Corona Roller

Description of Corona Roller

Corona roller used in corona treatment processes for polyfilms. It is designed to enhance the surface properties of polyfilm, such as BOPP and BOPET films, by subjecting polyfilm to a corona discharge. The corona discharge helps improve the film's ink retention, coating adhesion, and printability.

Corona roller is made from imported silica rubber and has resistance to voltage 220,000V and its eletrical performance can reach the usage requirements of imported equipment, featuring the aging resistance and more stable service lifespan.

Corona Roller Advantages

Huatao corona rollers 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.

Corona roller 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.
