The BestPack® MS2B2T Series carton sealer is operator-fed and adjustable. It is designed to lay two strips of tape on the bottom and two strips of tape top of the carton. This becomes necessary where the major flaps do not meet in the middle of the carton, and the cost of staples is not acceptable. This series sealer eliminates all together the need for staples or glue on the bottom and the top of the carton. The sealer has four tape heads, with two side belts driven by two electric 110V UL approved motors.
