No customer will accept cracks and splitting on folded packaging products
No customer will accept non-uniform packaging boxes
The paper structures and folding behaviour vary with
Fiber lenghts, fiber content, fiber orientation
Coatings, bond between coating and paper
Printed ink, varnish
Drying conditions affect the flexibility of the substrate
Environment – humidity in the pressroom
The cutting & creasing process itself has variations
Help to avoid runnability problems on the packaging line
Help to avoid waste because of unusable boxesincluded
Why creasing control is important
The Bead dimensions -a delamination parameter.
The Bead symmetry is driven by the folding point sharpness
Theory Practice
A crease is a
double fold!
A symmetrical edge givesyour product a highquality look.

Fiber-fiber bonds between plies are broken to make creased area behave like a hinge.
The knife abrasion changes the penetration depth of the rule.
Insufficient delamination
Bead Binding Extensive
Tension Spine fracturing
or crease end splitting.
