When you're setting up the cartoning, case packing, and erecting side of a packing line, the case sealer is where the box gets taped top and bottom before it moves to shipping. The real decision isn't whether to automate-it's how much carton-size range you need and what you're willing to pay. Four 110V belt-style machines are on the table, and they split into two practical camps: two compact TECHTONGDA units at the same listed price, and two wider-format machines that handle cases up to 500mm.
Quick take
The two least expensive listings are both TECHTONGDA belt sealers at $1,507.88, and they share the same model number, sumai056033. Both handle minimum box sizes of 80mm wide and 80mm high, and both stop at 300mm wide and 400mm high. The next step up, at $2,001.00, is the TECHTONGDA full automatic model, which expands the sealing range to 120mm-500mm in width and height. The $2,157.40 INTSUPERMAI model also covers 120mm-500mm, seals top and bottom at the same time, and adds a stainless steel travel path that's easy to keep clean. Your main call is simple: stay with 300mm-maximum boxes and pay less, or move up to the wider 500mm range and pay more.

Product notes
110V Automatic Belt Case Sealing Machine Carton Box Sealer Packing Machine
This TECHTONGDA machine is the lower-priced starting point and a good fit for compact cartons. It takes boxes as small as 80mm wide and 80mm high, and it uses a high-quality conveyor belt with strong grip to keep cases stable while the tape is applied. The tape position is aligned in the middle of the carton. The main limit is the 300mm maximum width, so anything wider won't fit through this unit. For a small-volume or smaller-box packing area, that trade-off is reasonable; for a broad carton mix, you'll need a wider machine.

The second TECHTONGDA listing carries the same listed price and the same model number, sumai056033. It shares the same BOPP/PVC tape compatibility, the same 1,000-box-per-hour rated speed, and the same 80mm minimum box size. The main distinction is in the title's emphasis on belt tape sealing, but the practical specs line up with the other entry-level unit. It also shares the same 300mm maximum-width limit. If you already have a specific configuration in mind and both listings look identical, this is the one that lets you secure the same capability at the same listed price.

This TECHTONGDA unit broadens the box range to 120mm-500mm in both width and height, so it's the right move when cases get bigger than 300mm. It also accepts sealing lengths from 150mm up to any continuous length, and it still reaches about 1,000 boxes per hour. It can also be paired with an automatic carton ink marking machine if you want production dates or batch numbers printed on the side of the box. The limitation is the 120mm minimum size: very small cartons below that won't be sealed. It's the practical middle choice for a wider mix of cases.

The INTSUPERMAI model, the highest-priced listing here, seals the top and bottom of the case at the same time and also covers the 120mm-500mm box size range. Its distinctive feature is the flat stainless steel travel path, which is easy to keep clean and creates smooth travel for the case. The painted steel body has anti-rust and anti-corrosion surface treatment. The limitation is the 120mm minimum case size and the higher listed price. If you want the wide range plus an easier-to-clean taping surface, this is the one to choose.
Final recommendation by use case
For compact cartons that stay under 300mm wide, either TECHTONGDA belt sealer at the lower end of the price range will do the job, and they're functionally matched on speed and tape type. For a wider mix of cases up to 500mm, the TECHTONGDA full automatic model gives you that extra range while keeping the same rated throughput. For a sealing line where cleaning matters and you want top-and-bottom taping plus a stainless steel travel path, the INTSUPERMAI model is the strongest fit, even at the highest listed price.
