Carton Glue Window Spec Checklist
Carton glue-window checklist: keep-outs, coatings, adhesives, and fold tests. Freeze windows before China print and folder-gluer runs.
Quick answer
A usable carton glue-window checklist freezes uncoated or treated keep-outs on glue flaps, adhesive family, and fold-test acceptance. Flood soft-touch or UV over glue flaps is a common cause of open side seams.
What belongs on the coating map?
Mark glue flaps, dust flaps, and any label panels that must stay adhesive-friendly. State whether plasma, primer, or varnish windows are approved.
How do you validate before mass print?
Glue production blanks at target speed and check fiber tear after dwell. Include soft-touch/foil SKUs that stress adhesion.
