Thanks to the Perfect Fold technology, corrugated packaging manufacturer Solpap has completely eliminated claims of curvature defects.

Elimination of curvature defects in corrugated cardboard packaging

Czech corrugated packaging manufacturer Solpap wanted to improve the bending quality of its packaging and reduce the number of complaints about the shape accuracy of its products.


We used Perfect Fold technology, which applies softening liquid contactlessly to the two lines of packaging to be folded. The softening liquid reduces the stiffness of the paperboard, allowing it to be folded precisely at the folding edges without much effort.


Since the installation of Perfect Fold, Solpap has not dealt with the curvature of the fold and has no complaint about this defect. Aside from zero complaints, the boxes are overall straighter and customers are happier.
