Core Advantages of Automatic Cold Glue System for Post-Press Packaging Production

Water-based cold glue has become the mainstream bonding material for paper packaging, and Keqi automatic cold glue dispensing system maximizes its inherent strengths to solve long-standing production pain points for printing factories.

First, outstanding environmental and safety performance. Cold glue is water-based low-VOC adhesive without heating links, cutting electricity consumption and avoiding scald risks from hot melt equipment. No toxic solvent volatilization complies with food, pharmaceutical and cosmetic packaging workshop standards. Equipment cleaning only needs clear water, eliminating chemical cleaning agents and waste disposal costs.

Second, stable precise gluing & low rejection rate. Servo quantitative dispensing valves realize adjustable glue flow, width and cut-off control, effectively solving glue overflow, stringing and missing glue common in manual brushing. Uniform thin glue layers keep printed carton surfaces intact without ink corrosion, perfectly matching high-end coated and laminated packaging requirements.

Third, low comprehensive operation cost. Cold glue raw material cost is lower than hot melt adhesive; the closed glue supply system reduces glue volatilization and solidification waste. Modular design supports quick retrofitting on existing folder gluers without large-scale line reconstruction, and simple daily maintenance cuts long-term spare parts investment.

Fourth, wide material compatibility. Cold glue forms flexible bonding layers after drying, not easy to crack when cartons fold or stack. It adapts to thin art paper, thick corrugated cardboard, embossed and special coated paper, covering most paper packaging production demands.
