Tomato Sauce Four Sealed Sachet Packing Machine

Why Tomato Sauce Packaging Is Technically Challenging

Tomato sauce may look simple, but from a packaging engineering perspective, it has distinct processing constraints:

1. Medium Viscosity with Fiber Content

• Contains pulp and micro-particles

• Non-Newtonian flow behavior

 Leads to:

• Inconsistent filling if control is poor

• Dripping or tailing during high-speed dosing

2. High Hygiene & Sealing Requirements

Tomato sauce is:

• Acidic

• Prone to contamination

 Requires:

• Clean sealing area

• No splash or residue near seal

3. Small Dose + High Volume Production

• Filling size: 10g per sachet

• High-speed expectation

 Challenge:

• Accuracy vs speed trade-off

Machine Configuration (From Production Sheet)

Core Machine

• Model: SF-960

• Configuration: 8 lanes

• Bag Type: 4-side seal sachet

• Structure: Full 304 stainless steel

• Control System: Siemens PLC + HMI

Engineering Design for Tomato Sauce

1. Precision Piston Pump Filling System

The machine uses a pneumatic piston pump, optimized for tomato sauce:

• Stable volumetric dosing

• Handles slight viscosity variation

• Anti-drip structure

 Result:

• Clean filling

• No stringing or splashing

2. Multi-Lane Synchronization (8 Lanes)

Running 8 lanes simultaneously requires:

• Independent lane calibration

• Film tension stabilization

• Synchronous sealing control

 Outcome:

• Uniform sachet length

• Consistent weight across all lanes

3. Sealing Optimization for Sauce Products

• Seal width: 5mm (side & center)

• Sealing pattern: stripe texture

 Why important:

• Prevents leakage

• Maintains seal integrity even if micro contamination occurs

4. Film Feeding Stability

• Total film width: 820mm

• Edge margin reserved: 20mm

 Ensures:

• Stable tracking

• No deviation at high speed

5. Clean Cutting & Easy Tear Design

• Straight tear notch

 Benefits:

• Consumer-friendly

• Ideal for fast food usage

Production Performance in Real Operation

 This level is considered industrial-grade stable production for sauce sachets.

Typical Use Cases

This configuration is widely used in:

• Fast food ketchup sachets

• Airline catering

• Sauce distribution packs

• Retail single-use condiment packaging

Scalability & Upgrade Path

This tomato sauce solution can be extended to:

1. Higher Capacity Systems

• Upgrade to 10–12 lanes

2. Full Automatic Packing Line

• Counting → Cartoning (or pouching)

 Suitable for:

• 50/100 sachets per box

3. Irregular Shape Sachets

• Customized shapes for branding

FAQ

1. Is this machine suitable for ketchup with pulp?

Yes. The piston pump system is designed to handle slight particles and pulp, ensuring stable filling without clogging or inconsistent dosing.

2. Can it run continuously at high speed?

Yes. The machine is engineered for continuous industrial production, maintaining stable performance at 30–35 cycles/min with consistent output quality.

3. What ensures clean sealing for tomato sauce?

Three key factors ensure sealing quality:

• Anti-drip filling system

• Precise temperature and pressure control

• Stripe sealing pattern to improve sealing strength

4. Can this machine be used for other sauces?

Yes. This machine is suitable for a wide range of low to medium viscosity sauces, including:

• Ketchup (tomato sauce)

• Mayonnaise
  

• Chili sauce

• Salad dressing

• Soy-based sauces

• Light mayonnaise (non-heavy type)

 Note:
For high-viscosity or thick paste sauces (e.g. peanut butter, heavy mayonnaise), a servo-driven piston system or screw dosing system is recommended for better performance.

5. Can the machine handle different sachet sizes?

Yes. The machine supports adjustable:

• Filling volume

• Sachet length

• Cutting position

This allows flexibility for different packaging specifications.

6. Is the machine suitable for food-grade production?

Yes. The machine is built with:

• 304 stainless steel structure

• Hygienic design

• Optional CIP cleaning system

Fully compliant with food industry requirements

Conclusion

This 8-lane tomato sauce sachet packing machine is a proven industrial solution that balances:

• High speed

• Filling accuracy

• Sealing reliability

• Food-grade hygiene

It is particularly suitable for manufacturers aiming to scale ketchup sachet production with consistent quality and minimal waste.
