Keqi Cold Glue Machine for Kraft Paper Bag Manufacturing

Kraft shopping bags, takeout food bags and retail kraft sacks rely on solid edge sealing. Many bag manufacturers used manual brushing glue with inconsistent thickness, leading to bag splitting during carrying. Keqi cold glue system perfectly fits bag making machines and folder gluers for kraft bag continuous production.

The equipment coats cold glue evenly on bag bottom and side seams. Water-based cold glue is food-safe, suitable for catering takeaway packaging that contacts food directly. Thick kraft paper has strong toughness, and cold glue flexible bonding bears repeated folding and pulling without seam opening. The machine works steadily at 45m/min, supporting 3000 finished bags per hour.

The cold glue unit matches rotary scrape silicone tape and easy-tear strip stations. The whole procedure (cold glue-silicone liner-easy tear) finishes inline. Closed glue supply reduces glue solidification waste. Factories cut manual workload greatly and guarantee uniform sealing quality of bulk kraft bag orders.
