Whether you are a fertilizer manufacturer, chemical repacker, or grains exporter, the 25kg Continuous Vertical Band Sealer is the final word in durability and performance.
Key Highlights
1. Heavy Pouch Handling – Up to 25kg
Capable of sealing industrial and commercial bags up to 25kg, ideal for bulk packaging of raw materials and processed goods.
2. Heavy-Duty Conveyor System
Powered by high-capacity motors and reinforced belts, the machine ensures smooth movement of bulky and large pouches without tilting or slipping.
3. Vertical Sealing Design
The vertical configuration is essential for powdery, granular, or semi-liquid contents, ensuring leakage-free sealing and better pouch positioning.
4. High-Temperature PID Controller
Digital temperature control allows accurate and consistent heat application suitable for sealing thick or multilayer pouches.
5. Optional Nitrogen Flushing
Built-in provisions allow for integrated nitrogen flushing, extending product shelf life for sensitive items such as agrochemicals or food grains.
6. Batch Coding Integration
Supports TIJ printers, emboss coders, or ink rollers to enable inline printing of Batch No, MRP, Expiry, etc.

Operating Instructions
-
Setup & Power On
Place the machine on a level surface. Connect power (single-phase or 3-phase depending on model). -
Adjust Sealing Head Height
Set the sealing head based on the height of the pouch (adjustable with lock knob). -
Set Temperature and Speed
Use the PID controller to set temperature (180–250°C typical) and conveyor speed. -
Place Pouch on Conveyor
Load a 25kg bag vertically on the conveyor with its open mouth aligned with the sealing jaws. -
Sealing Begins
Conveyor drives the pouch through the heated jaws, fusing the seal with uniform pressure. -
Batch Coding
Optional coding system prints details during the sealing pass. -
Output Collection
Sealed pouches exit the machine ready for shipping, storage, or secondary packaging.
Safety & Best Practices
-
Do not exceed 25kg pouch load to avoid conveyor strain
-
Always power off before maintenance
-
Ensure proper grounding for safe electrical operation
-
Keep sealing area clean to avoid contamination or seal failure
-
Use appropriate PPE when operating high-heat applications
