13000mm BOPET Film Corona Roller Synthetic Rubber Coated Rollers

Silicone rubber coated corona roller is a specialized component used in corona treatment processes for polymeric films. This roller enhances surface properties of materials like polyethylene films through corona discharge, improving ink retention, coating adhesion, and printability.

The process utilizes high frequency AC voltage (5000-15000V/m²) to create a corona discharge that generates low temperature plasma. This treatment:

• Produces free group reactions and polymer cross-linking
• Increases surface roughness and wettability to polar solvents
• Oxidizes and polarizes surface molecules through ionic electric shocks
• Enhances substrate surface adhesion properties

Corona treatment modifies substrate surface energy to improve bonding with printing inks, coatings, and adhesives. This post-processing method is particularly effective when flame treatment or coating methods are unsuitable for the substrate structure.

• Industry-leading quality with 100% spark testing prior to shipment
• Silicone rubber coating provides cost-effective, field-replaceable solution
• Delivers smooth, uniform surface for consistent film treatment
• Excellent dielectric properties for efficient corona discharge
