Our 3M-Matic™ Case Sealer 800ab with 3M™ AccuGlide™ 3 Taping Head seals the bottom center seam and manually adjusts to a wide range of case widths. It features a rugged 16-gauge welded steel frame and epoxy paint finish, with traction-grip belts to center and stabilize boxes for consistently accurate taping. 3M™AccuGlide™ 3 Taping Heads offer low impact sealing to protect cases. This box sealer uses 1.5-2" (36-48mm) tape to seal up to 40 uniform boxes per minute: case lengths of 6" (150mm) or more, widths of 4.5-21.5" (114-545mm) and heights of 4.75" (120mm) or more (max height depends on box stability through the sealer). The twin gear motor drives allow for high volume and heavy duty sealing applications, managing regular slotted containers (RSC) weighing up to 85 lbs.
