Poor bonding often roots in low‑surface‑energy film or UV‑coated carton surfaces, rather than glue quality. KEQI plasma surface treatment machine modifies material surface energy inline before gluing, removing the need for chemical primer agents.
Multiple‑gun configurations fit narrow small cartons up to wide corrugated sheets. It runs at full production‑line speed and connects directly to folder gluers as part of retrofitting projects. The dry physical treatment generates no dust or solvent fumes, complying with food‑packaging and pharmaceutical‑packaging safety standards.
When combined with KEQI cold glue or PUR hot‑melt systems, plasma treatment drastically reduces reject rates caused by delamination. For packaging plants fighting frequent‑peeling carton issues, KEQI plasma surface treatment machine delivers eco‑friendly, measurable production improvements.
