Gummed (water activated) tape.
By contrast, a ''case erector'' is equipment for setting-up flat (knocked-down) corrugated boxes and applying a closure to the bottom flaps.
Semi-automated
With semi automatic equipment, the operator typically fills and loads a box at the entrance to the case sealer; the box may or may not have the bottom flaps previously closed. The operator closes the top flaps and feeds the box in or through a machine which automatically applies the closure. This helps save time and controls the application of the closure materials such as
box sealing tape
Fully automated
Fully automatic equipment is available which does not require an operator. All functions, including closing the flaps, can be automated.
Other
Case sealers can also be categorized as either ''adjustable'' to fit production runs of a uniform box size or ''random'', capable of handling a mixed variety of box sizes without machine adjustment.
Several machine design options have been developed.
