Bottom Only Machines

Bottom only case sealers, or bottom case sealers are designed to close and seal the bottom of a case using glue. Bottom case sealers are designed to close the bottom minor flaps, apply glue to the flaps, close the bottom major flaps, and compress the case. Bottom case sealers are often used to seal the bottom of a case prior to the case being filled by product. Subsequently, the case with the sealed bottom is filled, either manually or automatically, and passed through a machine that closes and seals the top of the case (See Sealer Case / Top Only).
