The BestPack MSAG is a Semi-Automatic Uniform Tape Carton Sealer.

Yet still seal in the center of the carton on the bottom. The upper assembly and bottom assembly can accept center seal with 2″, 3″ and 6″ tape heads, or double sealing the top of the carton that can be accomplished with either 2″ tape heads or 3″ tape heads.
