The Preferred Pack PP702A is a semi-automatic random carton sealer featuring the new universal tape head that will run 2" or 3" tape with no changeover required. The operator simply folds the top flaps of the corrugated carton and feeds it into the machine; it will automatically adjust to meet the carton dimensions. The box size must be at least 6 inches in length and can have an unlimited maximum length to be properly sealed. This four belt drive (two top belts and two side drive belts) is a heavy duty versatile machine designed for dependable performance and easy operation. This model is designed for production runs where different size boxes will be used.
