Tomato Paste Sachet Packing Solution

Tomato paste is significantly more viscous than water or other free-flowing liquids.

For this project, the customer required packaging for a relatively thick tomato paste / tomato puree product.

Instead of using a standard liquid gravity filling system, the SF-960 is equipped with a:

6-lane servo diaphragm pump dosing system

The servo-controlled filling system is suitable for accurately controlling the filling quantity of viscous products in continuous multi-lane production.

This project is configured for:

• Tomato paste

• Tomato puree

• Thick sauces

• Similar viscous food products

The actual filling configuration should always be selected according to product viscosity, temperature and target filling weight.

6-Lane Tomato Paste Sachet Filling

The SF-960 uses six filling lanes, allowing six sachets to be produced in parallel.

The specified production speed is:

30–35 sachets/minute/lane

With all six lanes operating, the theoretical total output is approximately:

180–210 sachets/minute

Actual production speed can vary according to filling weight, product viscosity, film characteristics and operating conditions.

For factories producing large quantities of small tomato paste sachets, the multi-lane configuration provides much higher output than a conventional single-lane sachet filling machine.

30g & 70g Tomato Paste Sachets

The customer required two packaging sizes.

Both sachets use an approximately 80 mm finished bag width.

The production order specifies a total film width of:

960 mm without waste-edge cutting
980 mm including waste-edge cutting

The sealing width on the upper, lower, left and right sides is approximately:

8 mm

This configuration produces a clear four-side-seal sachet format for tomato paste.

Four-Side-Seal Sachet Making

The SF-960 forms individual sachets directly from laminated roll film.

During operation, the machine automatically completes:

Film Unwinding
→ Sachet Forming
→ Tomato Paste Dosing
→ Sachet Filling
→ Four-Side Sealing
→ Cutting

The packaging material specified for this project is:

Composite laminated film

with a thickness of approximately:

70–100 μm

The finished sachets use a four-side-seal structure with a toothed cutting design.

The machine also includes a connected-sachet function, allowing sachets to remain linked when required by the customer's packaging process.

Hot Filling for Tomato Paste

An important requirement of this Congo project is hot filling.

The product specified in the production order is thick tomato paste / tomato puree that is filled while hot.

Hot filling places additional requirements on the filling system, film selection and sealing stability.

For this reason, the packaging solution must consider:

• Product filling temperature

• Tomato paste viscosity

• Filling accuracy

• Film heat resistance

• Seal strength

• Continuous sealing stability

The final packaging material should be confirmed according to the customer's actual product temperature and storage requirements.

Servo Diaphragm Pump Filling System

The SF-960 uses a servo diaphragm pump filling system with six dosing channels.

Compared with simple gravity filling, a controlled pump system is better suited to thick products such as tomato paste.

The servo system allows filling parameters to be adjusted according to:

• 30g or 70g filling weight

• Product viscosity

• Production speed

• Filling temperature

• Actual product characteristics

This makes the machine suitable for customers who need to package more than one tomato paste sachet size on the same production line.

Machine Configuration

The machine is manufactured with an SS304 structure, while the parts that come into contact with the product are specified as SS316.

Other project specifications include:

Control system: Siemens
Power supply: 3-phase 400V ±10%, 50Hz
Packaging film: Composite laminated film
Film thickness: 70–100 μm
Seal type: Four-side seal
Seal width: Approx. 8 mm
Easy-tear notch: Straight-line easy-tear notch
Connected sachet function: Yes
HMI language: Chinese / English

Why Use a Multi-Lane Machine for Tomato Paste Sachets?

Small tomato paste sachets are usually produced in high quantities.

Using a 6-lane sachet packing machine allows six packages to be filled and sealed simultaneously instead of relying on a single packaging lane.

For this project, each lane is specified at 30–35 sachets per minute, giving a theoretical combined production capacity of approximately 180–210 sachets per minute.

This configuration is particularly suitable for manufacturers that need high-volume production of 30g and 70g tomato paste sachets.

Complete Packaging Process

The complete packaging process for this Congo tomato paste project is:

Tomato Paste Feeding
→ Servo Diaphragm Pump Dosing
→ Film Feeding
→ Sachet Making
→ Hot Filling
→ Four-Side Sealing
→ Easy-Tear Notch
→ Sachet Cutting / Connected Sachets
→ Finished Product Discharge

This allows the customer to complete sachet making, tomato paste filling and four-side sealing automatically on one production line.

Applications

This type of multi-lane viscous liquid sachet machine can be configured for products such as:

• Tomato paste

• Tomato puree

• Ketchup

• Chili sauce

• Thick sauce

• Other viscous liquid or paste products

The filling system should be selected according to the actual viscosity, filling temperature, filling weight and required output.
