KQ-HP40A four-nozzle plasma surface treatment machine is the flagship high-efficiency model for wide-format color box and large corrugated packaging production lines. Four independent plasma guns simultaneously treat multi-side glue flaps to double pretreatment efficiency compared with dual-nozzle models.Atmospheric cold plasma thoroughly activates BOPP laminated, UV-glossed and aluminized paper surfaces, enabling reliable bonding with standard water-based cold glue. No mechanical abrasion or chemical solvent is involved, meeting EU food contact packaging safety standards for export orders.Servo synchronous linkage matches ultra-high folder gluer speed up to 80 m/min for continuous non-stop mass production. Modular split nozzle structure simplifies maintenance and spare parts replacement, minimizing production downtime for large-scale packaging manufacturers.
