Vertical Packaging Machine with Liquid Pump
A Vertical Packaging Machine with Liquid Pump is an automatic liquid packaging system that combines a pump filling unit with a vertical form fill seal machine. It completes liquid supply, pump filling, bag forming, sealing, and cutting for liquid, sauce, paste, or semi-liquid products.
The pump filling system controls product flow and filling volume. It is suitable for sauce, liquid seasoning, soup base, edible liquids, detergent, dressing, oil, paste, and other pumpable materials. Depending on the product, the pump type and filling nozzle should be selected according to viscosity, particle content, target filling weight, and filling accuracy requirements.
Liquid packaging has different challenges from powder or granule packaging. Dripping, foaming, product residue, film compatibility, and sealing cleanliness can all affect final bag quality. For products with particles, such as chili sauce or liquid seasoning with granules, particle size and suspension stability should also be evaluated before choosing the filling system.
As part of Soontrue Group’s liquid packaging solutions, this system can be configured for small liquid sachets or larger liquid bags depending on the selected VFFS model. A complete line may include a liquid storage tank, pump filling system, VFFS bagger, finished bag conveyor, checkweigher, metal detector, cartoning machine, case packer, or other downstream equipment.
Before requesting a quotation, buyers should provide product viscosity, target filling weight, bag size, film material, required speed, filling accuracy requirement, particle content if any, and downstream packaging requirements.

The pump filling system controls liquid flow and filling volume. It can be selected according to viscosity, product type, filling weight, and required accuracy.
For liquid packaging, sealing cleanliness is critical. The filling nozzle, pump timing, bag size, and film material should be configured to reduce dripping and keep the sealing area clean.
The system can be configured for small sachets or larger liquid bags, depending on the selected VFFS machine and pump filling system.
The system can connect with storage tanks, pumps, mixers, VFFS machines, finished bag conveyors, checkweighers, metal detectors, cartoning machines, and case packers.
Servo control improves film pulling accuracy, bag length control, sealing synchronization, and stable bag forming during liquid filling.
This section can show pump filling, bag forming, sealing, and cutting for liquid products.
Through the video, buyers can check filling flow, drip control, sealing cleanliness, vertical sealing, horizontal sealing, cutting accuracy, and finished bag shape. For sauce or semi-liquid products, the video should show whether the product fills smoothly and whether the sealing area remains clean.
For larger liquid bags, the video should also show bag discharge and downstream transfer after sealing.

A vertical packaging machine with liquid pump can be used for small or large liquid bag packaging lines.
A typical system can include a liquid storage tank, pump filling system, VFFS machine, finished bag conveyor, checkweigher, metal detector, cartoning machine, and case packing system. For products with particles or high viscosity, Soontrue Group can evaluate pump type, nozzle design, filling speed, and sealing performance based on samples.
This configuration is suitable for sauce, liquid seasoning, soup base, edible liquids, detergent, dressing, oil, and other pumpable products.
Soontrue provides automated liquid seasoning packaging solutions for soy sauce, vinegar, cooking wine, cooking sauce, seasoning liquid, hot pot soup base, and other liquid condiment products.
Liquid seasonings may look similar to other liquid products, but their packaging requirements vary significantly. Low-viscosity products such as soy sauce and vinegar require accurate filling and clean sealing because the liquid flows quickly and can easily reach the sealing area. Other products, such as concentrated seasoning sauces or cooking liquids, may contain oil, spices, suspended particles, or higher viscosity ingredients that affect filling stability.
Soontrue configures liquid seasoning packaging lines according to product characteristics, filling volume, package format, sealing requirements, production speed, and downstream packing needs. The solution can cover liquid feeding, metered filling, sachet packaging, pouch packaging, spout pouch filling, inspection, case packing, and palletizing.
Soontrue provides automated shampoo packaging solutions for shampoo, conditioner, body wash, shower gel, hair treatment products, and similar personal care liquids.
These products are usually thicker than water and may behave differently depending on formulation, temperature, fragrance content, and added ingredients. Some flow smoothly, while others stretch, foam, or leave a product tail after filling. A small amount of shampoo around the pouch mouth can also affect sealing quality and create an untidy finished pack.
Soontrue configures shampoo packaging lines around product viscosity, foaming behavior, filling volume, package format, cleaning needs, production speed, and downstream packing requirements. The line can cover product feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, checkweighing, case packing, and palletizing.
Soontrue provides automated detergent liquid packaging solutions for liquid detergent, dishwashing liquid, hand soap, surface cleaner, laundry liquid, disinfectant liquid, and other household chemical liquid products.
Liquid detergents are usually more complex to package than simple water-based products because their viscosity, foaming behavior, chemical composition, and additives can vary significantly. Some products flow easily, while others are thick, create foam, or leave residue after filling. These characteristics directly affect filling accuracy, sealing cleanliness, and finished package appearance.
Soontrue configures detergent liquid packaging lines according to product viscosity, chemical characteristics, filling volume, package format, production speed, cleaning requirements, and downstream packing needs. The solution can cover liquid feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, inspection, case packing, and palletizing.
Soontrue provides automated water packaging solutions for drinking water, purified water, mineral water, flavored water, and other non-carbonated water products.
Water is easy to pump, but high-speed flexible packaging still requires precise control. Small changes in filling volume, film tracking, bag length, or sealing pressure can lead to uneven packs, weak seals, or leakage. Because water has low viscosity, any delay in nozzle shut-off can also leave liquid near the sealing area.
Soontrue configures water packaging lines around filling volume, package format, film structure, target output, hygiene requirements, and downstream handling. The line can cover water feeding, measured filling, sachet forming, pouch filling, sealing, inspection, case packing, and palletizing.
Soontrue provides automated milk packaging solutions for fresh milk, flavored milk, dairy beverages, milk drinks, and similar liquid dairy products.
Milk packaging places greater demands on hygiene, filling stability, and seal integrity than many general liquid applications. The product can foam during filling, leave residue around the pouch opening, or spoil quickly if the package is not sealed correctly. Cold-filled and heat-treated dairy products may also require different packaging materials and line conditions.
Soontrue configures milk packaging lines around the dairy product, filling temperature, target volume, package format, hygiene requirements, output, and downstream handling. A complete system can cover milk feeding, metered filling, sachet packaging, pouch filling, sealing, checkweighing, case packing, and palletizing.
Soontrue provides automated juice packaging solutions for fruit juice, vegetable juice, mixed juice drinks, juice concentrate, flavored juice beverages, and similar liquid products.
Juice packaging requirements change with the product itself. Clear filtered juice behaves differently from pulpy juice, concentrated juice, or drinks containing fruit fibers. Filling temperature, foam, suspended particles, sugar content, acidity, and package size can all affect filling stability and seal quality.
Soontrue configures juice packaging lines around the actual beverage, filling volume, package format, hygiene requirement, production speed, and downstream packing method. The line can cover liquid feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, checkweighing, case packing, and palletizing.
Soontrue provides automated edible oil packaging solutions for cooking oil, vegetable oil, soybean oil, sunflower oil, corn oil, olive oil, blended oil, and other food-grade oil products.
Oil packaging looks simple, but small details on the line can directly affect finished pack quality. Oil can leave residue near the filling area, weaken the seal if it reaches the sealing surface, and make flexible packs harder to handle after filling. For stand-up pouches or spout pouches, filling stability, pouch opening, sealing accuracy, and finished pouch shape all need to be considered.
Soontrue configures edible oil packaging lines around oil type, filling volume, pouch format, sealing requirement, package strength, production speed, and downstream packing method. A complete line can cover oil feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, checkweighing, case packing, and palletizing.
Soontrue provides automated sauce packaging solutions for ketchup, chili sauce, soy sauce, salad dressing, cooking sauce, dipping sauce, and other liquid or semi-liquid condiments.
Sauce packaging is not only about filling liquid into a bag. Different sauces behave very differently on the line. Thin sauces may drip easily, thick sauces may leave product tails after filling, and chili sauces or dressings with particles may cause unstable filling if the pump and filling path are not selected correctly.
Soontrue configures sauce packaging lines around the actual product condition, package format, filling volume, sealing requirement, and downstream packing method. A complete line can cover sauce feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, checkweighing, cartoning, case packing, and palletizing.
Soontrue packaging machines support various flexible packaging formats to meet different product shapes, sizes and production requirements. From standard pillow bags to customized bag options, we provide reliable packaging solutions for diverse applications.
