Why Are Special Cartons Difficult to Glue?
Standard carton structures are relatively simple.
However, special packaging may contain:
- Multiple folding points
- Narrow glue areas
- Irregular structures
- Thick paperboard
- Coated surfaces
These factors can make adhesive application more challenging.
The Positioning Problem
When cold glue is used alone, the carton may move before the adhesive develops sufficient initial bonding.
This can cause:
- Misalignment
- Open edges
- Deformed cartons
- Production rejects
KQ Hybrid Solution
KQ can combine hot melt and cold glue application on the same folder gluer.
Hot melt provides rapid positioning.
Cold glue provides the main bonding.
This approach helps separate initial fixation from final adhesion.
Better Control for Complex Packaging
The adhesive application system can be customized according to:
- Box structure
- Machine speed
- Glue position
- Adhesive type
- Number of application points
This makes the solution suitable for specialized packaging projects.
Contact KQ Automation if your folder gluer is producing a special carton that is difficult to bond consistently.
