Sealer case or case sealing equipment is designed to seal cases using either tape or glue. Case sealer equipment can have many different capabilities depending on the application the particular case sealer was designed for beyond tape and glue sealing. Case sealers can be either automatic or semi-automatic. Automatic refers to a case sealer that automatically closes the minor and major top flaps for an open case. Semi-automatic case sealers require that the minor and major top flaps be closed prior to being processed by the case sealer.
