What Types of Case Sealers Are Available?

A case sealer is a packaging machine that automatically completes carton sealing, tape application, and tape cutting through mechanical operation. It ensures consistent tape length on both the front and rear of the carton, preventing issues such as uneven tape length, tape waste, and poor appearance commonly caused by manual sealing.

1. Semi-Automatic Case Sealer

Ａsemi-automatic case sealer allows manual adjustment of carton width and height by turning adjustment screws.Operators simply push the carton into the side-belt conveyor, and the machine completes the sealing process.
