When a cartoning, case packing, and erecting operation still relies on manual taping, the upgrade decision often comes down to two TECHTONGDA 110V belt sealers: the Automatic Belt Tape Sealing Machine and the Full Automatic Belt Sealing Machine. Both run on 110V with a 180W rating, apply BOPP/PVC adhesive tape, and run at roughly 1,000 cartons per hour. The difference is how much box-size flexibility you need and how much you're ready to invest in the machine.
Quick verdict
Go with the automatic model if your cartons are compact and you want a no-fuss solution. Go with the full automatic model if you handle larger boxes and want a more automated workflow.
At a glance
| Model | Listed Price | Price Bar | Carton Width Range | Carton Height Range |
| 110V Automatic Belt Tape Sealing Machine | USD 1,507.88 | | 3.15in-11.8in | 3.15in-15.7in |
| 110V Full Automatic Belt Sealing Machine | USD 2,001.00 | | 4.72in-19.68in | 4.72in-19.68in |
Where each machine wins
The automatic model wins when your boxes are on the smaller side. It accepts compact cartons and handles narrow, short boxes comfortably. The full automatic model wins when you need more headroom. It stretches to handle taller and wider cartons, and it seals the top and bottom of the carton in one pass. It can also be used alone or tied into a packaging line, and it can be paired with an ink marking machine for batch or date printing on the side of the box.
Product notes
Automatic Belt Tape Sealing Machine
This is the lower-priced belt sealer of the two, and it's aimed at smaller cartons. The conveyor belt keeps boxes centered while the machine aligns the tape on the middle of the carton, and the sealing range is adjustable to match the box height and width. Its maximum packing size is 11.8in wide by 15.7in high, so narrow and short boxes are right in its comfort zone. The main limitation is that maximum size: if your cartons are wider than 11.8in or taller than 15.7in, this machine will not fit them. For those larger cases, the full automatic model is the one to look at.
Full Automatic Belt Sealing Machine
This unit gives you extra space for bigger cases. It handles a sealing width and height from 4.72in up to 19.68in, and its sealing length runs from 5.90in to infinite, so long cartons are not a problem. The auto top-and-bottom sealing action completes the box in one pass. The higher listed price is the trade-off: you're paying for the wider range and the two-sided sealing motion. If your cases never exceed the smaller machine's 11.8in by 15.7in limit, this fuller range may be capability you don't need. It can also be paired with an automatic carton ink marking machine for batch and date printing.
Final choice by use case
For small, compact cartons, the Automatic Belt Tape Sealing Machine is a sensible match. For wide or tall cartons, and for operations that need more automation, the Full Automatic Belt Sealing Machine is the more capable machine. Because both machines share the same 180W rating and roughly 1,000-carton-per-hour speed, the main decision is really your box dimensions and the features you need.
