Turn on the power, the motor starts, and the roller conveyor & drive belt carry the bottom-sealed box forward.

When the carton gets in contact with the pressure sensitive tape head, the tape applicator starts to work, completing its tasks such as taping, wiping, cutting off, sealing.


For the carton sealing tape machine, some adopt side belts drive, some introduce top & bottom belts drive.

Side belts drive carton sealer is suitable for sealing narrow cartons;


Top & bottom belts drive carton sealer is suitable for sealing tall cartons.


Water Activated Tape Case Sealer

Most of the cartons nowadays are made of recycled materials, in view of this, we SiroSilo released a water activated tape case sealing machine, because WAT tape has a stronger sealing effect than BOPP tape on recycled carton materials.

Moreover, the water activated tape is degradable, the wider its application, the more eco-friendly.

The water activated tape’s main material is kraft paper, after coating starch or corn glue on the kraft paper, the drying machine dries it, then the slitting rewinding machine converts it into WAT tape rolls.


When using gummed tape, lightly wipe it with a damp cloth on the surface, it will be sticky.

Clients highly appreciate our SiroSilo water activated tape case sealing machine’s following selling points.

  • Filter Sponge

The kraft paper tape can soak the water in the sponge, then seal the box after it becomes sticky.


The sealing is firmer & more beautiful, with strong retention, quite suitable for high-end carton sealing.

  • Powerful Motor

The sealer equips with 2 powerful motors, these motors’ load capacity is large, thus the sealer can easily transport heavier boxes, its application becomes wider.


  • Sealing Height & Width Adjustable

With ergonomic hand wheel, you can adjust the sealing height & width as you like, thus your case sealing equipment can handle cartons of different sizes.

  • Denser Roller Conveyor

Ensures more stable carton conveying without jam, supports larger size range of corrugated containers.


Case Sealer Hot Melt

The case sealer hot melt equips with a hot melt glue dispenser.

The dispenser melts the glue into a liquid, then spray the liquid glue on the carton’s surface through its nozzle.

After the hot melt glue gets cool, it bonds the carton’s flaps together firmly.

Please watch the following demo video of case sealer hot melt, you can understand its working process more clearly.

Many customers have bought our SiroSilo case sealer hot melt, according to their feedback, they chose case sealer hot melt based on the following points.

  • Good Packaging Quality

Packaging cartons must be able to withstand temperature & humidity changes, and rough handling.

The hot melt adhesive bonds well with wet objects, its penetration ability is strong.

In fact, it imposes a physical & chemical bonding effect between the corrugated paper & the liner board, thus enhancing the bonded carton’s overall strength, which is not easy to deform & crack.


Hot Melt Glue

The hot melt glue dispenser can also spray glue on key parts of various shapes, such as the carton’s inner flap.


Secondly, hot melt adhesive can withstand low temperatures of -40°C,its storage period is as long as 2 years, and it just needs a small storage area;

Whatsmore, hot melt adhesive comes with an anti-theft function. Since the adhesive penetrates into the corrugation, any opening attempt will tear the carton flap.


  • Beautiful Appearance

Nowadays, merchants also advertise their products on the packaging carton. Therefore, the fewer visual obstacles, the better.

Adhesive tape often blocks the advertising information on the carton;


The hot melt adhesive bonds the flaps inside the carton, this kind of sealing will not affect the display of carton ads.

  • Low Cost

Hot melt glue closure is fast, the entire bonding process takes 1-3s, and the glue replenishment doesn’t cause downtime.

It is suitable for mass packaging, with low energy consumption & cost. The sealing cost of hot melt adhesive is about USD$5.00/1000 boxes in China, and the cost of tape sealing is about USD$18.80/1000 boxes.
