What is a Liquid Pump Packing Machine??

A Liquid Pump Packing Machine is a type of Vertical Form Fill Seal (VFFS) system that uses liquid pumps to measure and dispense liquids or pastes into bags.

🔹 How it works step by step:

  • Film forming – Packaging film is formed into a bag tube around a forming collar.
  • Dosing – A piston or peristaltic liquid pump draws liquid from a storage tank and dispenses it into the formed bag.
  • Sealing – Vertical and horizontal sealing jaws close the film, ensuring a leak-proof seal.
  • Cutting – The finished bag is cut and discharged.

🔹 Why use liquid pumps?

  • Precision dosing – pump rotation or piston stroke ensures accurate volume.
  • Flexibility – handles both low-viscosity liquids (milk, soy sauce) and high-viscosity pastes (jam, chili paste).
  • Hygiene – food-grade stainless steel design with easy cleaning.
  • Consistency – every bag has the same volume, minimizing giveaway.

🔹 Best suited for:

  • Liquids & pastes where accuracy and hygiene are critical.
  • Industries such as food, beverage, chemical, and pharmaceutical.

🔹 Limitations to consider:

  • Not suitable for dry products (better use volumetric cup, multi-head, or auger).
  • Requires proper cleaning for sticky pastes → usually comes with CIP (clean-in-place) options.

👉 In summary: The Liquid Pump Packing Machine is the go-to solution for liquid and paste packaging, combining accuracy, hygiene, and sealing security.
