CS-500K Automatic Bottom Folding Case Sealer

Equipment Overview

The automatic bottom-folding carton sealing machine automatically completes the folding of the four bottom flaps of the carton and the bottom tape sealing process. The operator only needs to place the opened empty carton upside down on the infeed end; through the conveying and flap-folding mechanisms, the machine folds the front, rear, left and right bottom flaps in sequence and automatically applies the bottom sealing tape, while the top opening of the carton stays open to facilitate subsequent product filling. It can be directly connected to a case packing production line and is widely used with automated packaging production lines in the food, daily chemical, e-commerce and hardware industries.
