Glueing / Carton Sealing

Glueing (also known as carton sealing) is a packaging industry term referring to the process of converting die-cut cardboard into cartons through glue application, folding, and pressing. In foreign trade, it commonly appears in packaging requirements, order specifications, or production process descriptions. Usage scenarios include: customers specifying packaging methods (e.g., 'glueing required, no stapling'), distinguishing glueing vs. stapling costs in quotations, and inspecting glueing strength during quality checks. Notes: Glueing requires specifying adhesive type (hot melt glue, white latex, etc.), bonding position (side seam, bottom), and whether automatic glueing is used; it differs from 'stapling' in that glueing has no metal staples, offering better appearance but possibly lower load-bearing capacity; it is sometimes confused with 'carton sealing', but sealing is broader while glueing specifically refers to carton forming. Foreign trade professionals should clearly specify glueing standards in contracts to avoid returns due to poor adhesion.
