- What the film must do
- Board from 250 to 450 gsm with heavy ink coverage. The film must bond over solid areas without lifting at the crease and must not add enough stiffness to break the fold.
- Common fault and cause
- Lifting at the crease usually comes from insufficient nip pressure or a board that cooled before the adhesive set. Deep folds on 400 gsm board benefit from a high-adhesion grade and pre-creasing.
