Corona Machine

1. Surface energy improvement Principle: Plasma is generated on the surface of materials through high-voltage corona discharge, causing the surface molecules of materials (such as plastics, films, metal foils, etc.) to polarize or introduce oxygen-containing polar groups (such as -OH, -COOH). Effect: Reduces the contact Angle, enhances wettability, and makes it easier for inks, adhesives or coatings to adhere. 2. Cleaning and activation Removing contaminants: Halo discharge can decompose weak boundary layers such as surface grease and dust. Microscopic roughening: Forming tiny etches at the nanoscale to enhance mechanical interlocking capabilities

After being treated with corona, the surface properties of PVC (polyvinyl chloride) film are significantly improved, making it perform better in fields such as lamination and packaging. The electrostatic discharge machine introduces polar groups and increases roughness on the surface of PVC film through high-voltage discharge, thereby enhancing adhesion, wettability and bonding strength.

This is a laminating production line, with the corona machine to use better, 1. Corona treatment to make the material surface activity enhancement, reduce the bubble generation, improve the lamination precision, so that the lamination is more flat 2. Can change the surface properties of some difficult to fit the material, so that the flat laminating machine can be processed more different material combinations.
