SP-304 Semi-Automatic, Uniform Case Sealer

The SP-304 semi-automatic case sealer with packing anvil is a complete ‘end of line’ solution. It improves end of line speed and efficiency by removing the need to fold six of the eight flaps on the case. This results in outcomes that are up to 40% more effective than hand sealing. The SP-304 case sealer uses simple adjustments and no air or pneumatics are used in the machine, which makes it reliable, simple and portable.

The SP-304 case sealer is side-belt driven, and it operates by propelling cartons through a folding section that folds all major flaps and one upper flap. Repetitive motion from hand sealing is reduced, and productivity is increased with this innovative design.
