Used case sealers apply tape to boxes on both the top and bottom to secure it for shipping. They come in both semi-automatic and fully automatic. Semi-automatic case sealers typically have the operator manually fold down the pre-erected box’s flaps. The cases are also manually loaded into the device, which is fine for applications that aren’t high traffic.
Typically case sealers have side-mounted compression rollers to ensure that the box is tightly sealed, and the side belt drives ensure that the box stays completely square. For different sized cases or boxes, the case sealer can be adjusted via two manual crank handles.Fully automatic case sealers fold the flaps of the box down automatically and are usually hooked up to a conveyor system. Adding to a conveyor system is really one of the only ways to make it fully automatic because otherwise, you would need to hand load boxes into the device. Some automatic case sealers automatically adjust to different box dimensions.
