Key benefits of folding carton gluing

High speed

Reliable gluing even on high-capacity, fast packaging lines.

Clean application

Precise metering with no smearing, overflow or burning of adhesive.

Adhesive savings

Application in precise dots or lines reduces adhesive consumption.

Coated and recycled cardboard too

A reliable bond even on demanding and recycled materials.

Consistent quality

The same result in every batch thanks to a controlled application pattern.

Fast format changeover

Easy integration into new and existing lines and a quick change of order.

How it works and what technology is used

Hot melt adhesive is applied by a jetting (contactless) application head in precise dots or beads onto the box flaps. After folding and pressing, a strong bond forms within a few seconds. Pattern control monitors where and how much adhesive is applied – ensuring consistent quality and material savings.

  1. Adhesive application onto the flaps

    The jetting head applies precise dots or beads of hot melt adhesive onto the flaps of the open box.

  2. Folding and pressing

    The box is folded and pressed – the adhesive bonds the flaps across the entire bond area.

  3. Rapid bond formation

    The bond sets within a few seconds and the box is immediately ready for filling or dispatch.

  4. Pattern control and quality control

    Pattern control governs precise application and maintains consistent quality across the whole batch and when the format changes.
