Laminated gift boxes, cosmetic cartons and e-commerce packaging are prone to edge delamination after long-term storage or extrusion. The core reason is the inert and smooth surface of lamination films, which makes it hard for adhesives to penetrate and bond firmly.
KEQI plasma surface activation technology breaks through the bonding limitation of laminated materials. Micro plasma bombardment roughens the smooth film surface at the microscopic level and generates active functional groups, greatly enhancing glue adsorption and adhesion force. The treated carton bonding layer is resistant to bending, extrusion and temperature changes.
Different from disposable chemical treatment, plasma modification has stable and long-lasting effects. It solves the post-delivery delamination problem of finished packaging, reduces customer complaints and rework losses, and improves the market competitiveness of packaging products.
