Universal Seal™ Heavy Duty SS Vertical Continuous Band Sealer with Nitrogen Flushing System

Description

The Universal Seal™ Heavy Duty SS Vertical Continuous Band Sealer with Nitrogen Flushing System is a professional packaging machine designed for continuous sealing of high-grade and laminated pouches in a vertical position. Its stainless steel construction provides durability, corrosion resistance and easy cleaning, making it suitable for regular commercial and industrial packaging operations.

The integrated nitrogen flushing system introduces nitrogen gas into compatible pouches before sealing, helping reduce oxygen inside the package. This can help maintain product freshness and reduce oxidation when used with suitable products and barrier packaging materials. It is especially useful for snacks, dry fruits, grains, spices and other products where controlled-atmosphere packaging may be beneficial.

With an adjustable sealing speed of 0–12 m/min, sealing width of 6–12 mm and temperature range of 0–300°C, the machine can be configured according to different compatible pouch materials and production requirements. The conveyor supports a maximum transport weight of approximately 3 kg.

The vertical configuration allows filled pouches to remain upright while passing through the nitrogen flushing and sealing sections, making the machine particularly suitable for products that may be difficult to handle on a conventional horizontal band sealer.

Applications

Food Packaging: Suitable for snacks, chips, namkeen, dry fruits, nuts, spices, grains and other compatible food products. Nitrogen flushing can help reduce oxygen exposure and support freshness.

Agricultural Products: Can be used for compatible packaging of grains, seeds and selected agricultural products requiring continuous pouch sealing.

Pharmaceutical & FMCG Packaging: Suitable for selected products packed in compatible heat-sealable pouches.

Chemical Products: Can be considered for compatible dry or powdered products where the product and packaging material are suitable for the machine and nitrogen-flushing process.

Industrial Packaging: Suitable for various commercial and industrial products requiring vertical continuous pouch sealing.

How to Use

1. Machine Setup:

Place the machine on a stable and level surface. Check that the conveyor, sealing section and adjustment components are correctly positioned.

2. Connect Power:

Connect the machine to a suitable 220V, 50Hz electrical supply.

3. Connect Nitrogen Supply:

Connect the nitrogen gas line to the designated nitrogen inlet using a suitable regulator and compatible tubing. Check all gas connections for leakage before operation.

4. Adjust Temperature:

Set the sealing temperature according to the type and thickness of the pouch material.

5. Adjust Conveyor Speed:

Select an appropriate conveyor speed according to the pouch material, product and required sealing quality.

6. Set Nitrogen Flow:

Adjust the nitrogen flow according to the pouch size, product type and packaging requirement.

7. Load the Pouch:

Fill the pouch and make sure the sealing edge is clean, dry and properly aligned. Position the pouch upright on the conveyor.

8. Start Flushing & Sealing:

Guide the open edge of the pouch through the nitrogen flushing and sealing section. The machine continuously transports the pouch while completing the flushing and heat-sealing process.

9. Inspect the Finished Pack:

Check the seal for proper alignment, strength and consistency. Adjust the temperature, speed or nitrogen flow if required before bulk production.

Maintenance

Regular Cleaning: Keep the conveyor, sealing section and stainless steel surfaces clean and free from product or packaging residue.

Inspect Sealing Components: Periodically inspect the sealing belts, Teflon belts, rollers and heating components for wear or damage.

Check Nitrogen Connections: Inspect nitrogen tubing, fittings and connections regularly for leakage, looseness or damage.

Check Operating Settings: Ensure temperature, conveyor speed and nitrogen flow are appropriate for the pouch being processed.

Remove Debris: Clear any pouch material or product residue from moving components to help prevent jams.

Electrical Inspection: Periodically inspect the power cable, switches and visible electrical connections for damage.

Always switch off and disconnect the machine from the electrical and nitrogen supplies before cleaning or maintenance.

Important Notes

• Recommended for high-grade and laminated heat-sealable pouches.
• Conveyor colour and control panel design may vary depending on the available production batch.
• Nitrogen cylinder, regulator and external gas-supply accessories should be confirmed separately unless specifically included.
• Actual nitrogen-flushing effectiveness depends on factors such as nitrogen purity, gas flow, residual oxygen, product type and pouch barrier properties.
• Always conduct sample sealing and flushing trials before starting bulk production.
