Plasma Treatment for Laminated & UV Varnished Cartons

Many packaging manufacturers struggle with weak adhesion on laminated and UV-coated cartons. Ordinary gluing methods easily lead to carton opening and high reject rates. Keqi plasma surface treatment equipment effectively increases surface tension without damaging printing layers.

The plasma activates carton surfaces at high speed, delivering stable bonding performance for cold glue, hot melt and double-sided tape. The inline structure can be installed directly on folder gluers, operating synchronously with production speed. No primer or chemical solvent is needed, meeting environmental requirements for food, pharmaceutical and cosmetic packaging.Factories can reduce rework losses and stabilize product quality during continuous mass production. It is an economical upgrade solution to solve common adhesion problems in post-press processing.
