Case erector and case sealer
The erector opens and bottom-seals carton blanks; the sealer tapes cases shut, and flap-folding models close the flaps too. Sold singly or as an end-of-line packing line.
The erector opens and bottom-seals carton blanks; the sealer tapes cases shut, and flap-folding models close the flaps too. Sold singly or as an end-of-line packing line.
A case erector takes a flat carton blank from its magazine, opens it, folds the bottom flaps and seals them with tape or hot melt, then passes the case to packing. A standard case sealer tapes cases whose flaps are already closed; a flap-folding sealer closes the top flaps itself. Fixed-size sealers suit a single case size; random sealers sense each case's width and height and suit e-commerce and mixed shipping. Both are sold singly or linked with packing, weighing, labeling and palletizing into an end-of-line packing line.
Typical uses
- Factory packing lines
- Outbound in e-commerce and 3PL warehouses
- Export packing for food, appliances, textiles
- Upstream of palletizing
How to choose
- Case sizes and changeovers: fixed-size machines for one size per batch and infrequent changes; random sealers for mixed cases
- Cases per minute
- Tape or hot melt
- Whether a machine should close the top flaps: if so, choose a flap-folding sealer; overfilled, bulging cases need the packing quantity adjusted first
When it is not the right choice
- A few hundred cases a day in many sizes: semi-automatic equipment or manual work is cheaper
- E-commerce customers want easy opening: use tape rather than hot melt
- Storage below 0 °C: confirm the hot-melt type
