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
