Case sealers can be classified into two types: glue case sealers and tape case sealers. A glue case sealer applies glue to the short flaps of a box and seals it with the long flap of the box. This prepares the box for shipping. This equipment can be semi-automatic or automatic, random, or uniform.
A tape case sealer can be automated or semi-automatic, random or uniform. Semi-automatic tape case sealers apply the tape after the flaps are folded down, whereas automatic tape case sealers fold the flaps and apply the tape. Uniform case sealers adjust their output according to specific case sizes, whereas random case sealers adjust their output according to the different case sizes.
