Automatic liquid packing machine complete process flow
- Film feeding & positioning: The packaging film is unwound and conveyed; the photoelectric eye tracks marks on the film to ensure accurate sealing and cutting positions.
- Bag forming: The packaging film is folded by the former to form the target bag shape.
- Metering & filling: Liquid or paste materials are filled into bags according to the set volume.
- Sealing & cutting: The machine seals the top and bottom and cuts automatically at the preset bag length.
- Optional auxiliary processes: Date coding, air exhausting, inflating, corner rounding and easy-tear notch making can be realized simultaneously.
- Discharging & counting: Finished packages are output automatically while the machine counts the finished bags.

Συχνές ερωτήσεις
Can this machine pack high-viscosity pastes?
Yes. Matching filling assemblies are available for thick pastes such as sauces and creams to ensure smooth feeding.
Can I change the pouch size later?
Pouch length can be adjusted directly on the control panel. Replacing the forming former is required to change pouch width.
Is it suitable for food sauce packaging?
Parts in contact with materials are made of 304 stainless steel, easy to clean and meet basic food hygiene requirements.
Does the machine need an air compressor?
Yes. It adopts pneumatic components and requires stable air supply.
How do you choose the right liquid packing machine?
- Material property: Confirm whether the material is regular liquid or high-viscosity paste, as viscosity determines the filling structure.
- Pouch specification: Confirm sealing style and pouch size in advance. A new forming former is required to change pouch width.
- Production capacity: Match the machine speed according to your target output and order volume.
- Optional accessories: Decide if you need extra functions such as coding, degassing, inflating and corner rounding.
- Air supply: An air compressor is required, with stable working pressure of 0.6–0.7MPa.
- Layout space: Reserve enough room for machine placement, material handling and maintenance.
What is the price of liquid packing machine?
There is no fixed price for vertical liquid & paste packing machines. The final cost depends on configuration, custom filling design, pouch size, optional attachments, and shipping arrangements.
