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.
