What you are dealing with
- Corrugated board with a higher grammage resists folding – a skewed or incomplete fold.
- Cracking of the board surface and damage to the print at the fold.
- Complaints about skewing and downtime when folding demanding materials.
How Kaletech solves it
We supply the Perfect Fold application system, which precisely softens the crease line of the board before folding. The board then folds straight, sharp and repeatably – without cracking or skewing, even with higher grammages and multi-layer board.
We design and integrate the system into your production line and take care of setup, operator training and service.
Who the solution suits
- Packaging and carton manufacturers

Key benefits of softening board with the Perfect Fold system
A straight, sharp fold
A precise fold with no skewing or incompletely closed edges.
No cracking
The softened crease line does not crack or damage the print.
Fewer complaints
Higher packaging quality significantly reduces complaints about skewing.
Faster folding
Smooth folding even in demanding production conditions.
Even high grammages
A reliable fold even with thick, multi-layer corrugated board.
Line integration
Easy connection to new and existing production lines.
How it works and what technology is used
The Perfect Fold system softens the crease line of corrugated board in a precisely metered way. The fibres at the point of the future fold are loosened, so the board folds straight and sharp without cracking – even at high line speed. This is an application within a cold gluing system, which we integrate into existing and new production.
Identifying the crease line
Based on the blank, the system identifies the positions of the future folds on the board.
Targeted softening
Perfect Fold precisely applies the softening directly into the crease line.
A straight, sharp fold
The board folds precisely at the crease, without cracking or skewing.
A repeatable result
Consistent fold quality even with high grammages and multi-layer board.
