Packing tape and duct tape may be selected for different workflows. Many packing tapes use BOPP film, whereas duct tape is often fabric-reinforced; characteristics vary within both groups.
Carton sealing needs
Carton quality, weight, application method and shipping conditions drive selection. For automatic machinery, verify roll dimensions and machine compatibility with the supplier.
Comparative trial
Test candidates on the same carton under representative shipping conditions and record flap opening, adhesion and application time. Check duct tape separately for residue on removal.
