The RPS-05 side taping case sealer is primarily designed for sealing of special packages by sealing both sides of cases at the same time. The taping heads are installed on both sides of the case sealing machine, quite different from conventional case sealers, and moved with cartons transported between top and bottom drive belts. During this process, carton boxes will be sealed in short time. When box size need to be changed, manual adjustments are required to accommodate different case sizes. This side taping carton sealer can be integrated into an automatic packaging line having carton erector.
