YL-400B Large Volume Liquid Vertical Packaging Machine
The YL-400B Large Volume Liquid Vertical Packaging Machine is designed for large-volume liquid packaging from 500 g to 5000 g per bag. It is used for automatic bag forming, liquid filling, sealing, and cutting for larger liquid packs rather than small sachet packaging.
This model is mainly suitable for liquid and semi-liquid products such as sauces, liquid seasoning, soup base, edible liquid products, detergents, and other pumpable materials. Compared with small-dose liquid machines such as the YL-150A, the YL-400B is positioned for larger filling weight, stronger liquid handling, and more stable sealing for heavier bags.
The YL-400B works with a pump filling system to control filling volume and flow. For thicker sauces, liquid products with particles, or products with special viscosity, the filling system should be selected based on viscosity, particle size, filling weight, and required accuracy.
As part of Soontrue Group's liquid vertical packaging machine series, the YL-400B is suitable for factories that need 500–5000 g liquid bag packaging with stable filling and reliable sealing. It can be used for retail large packs, catering packs, food service packs, and industrial liquid packaging applications.
Before requesting a quotation, buyers should provide product viscosity, target filling weight, bag size, film material, filling accuracy requirement, target packing speed, particle content if any, and whether downstream conveying or case packing is required.

The YL-400B is built for large-volume liquid packaging. Actual speed depends on filling weight, product viscosity, bag size, pump filling capacity, film material, and sealing requirements.
The machine is designed for liquid filling from 500 g to 5000 g per bag. The pump filling system helps control filling volume, flow stability, and filling accuracy for larger liquid packs.
Large liquid bags place higher demands on seal strength and bag stability. The YL-400B is designed to support reliable sealing for heavier liquid-filled bags when matched with suitable film material and sealing parameters.
The machine can be used for sauces, liquid seasoning, soup base, edible liquids, detergents, and other pumpable products. For products with particles or higher viscosity, the filling system should be evaluated based on product samples.
The servo control system improves film pulling accuracy, bag length control, sealing synchronization, and cutting stability, helping maintain consistent bag quality during large-volume liquid packaging.
This section can show the YL-400B packaging 500–5000 g liquid products into vertical bags.
Through the video, buyers can check pump filling flow, filling volume stability, bag forming, sealing strength, cutting accuracy, and finished liquid bag shape. For larger liquid packs, the video should also show how the filled bag is discharged and transferred after sealing.
If the product is viscous or contains particles, the video should show whether the filling process remains smooth and whether the sealing area stays clean.

The YL-400B can be used as the main bagging machine in a large-volume liquid packaging solution.
It can connect with liquid storage tanks, pumps, mixing or holding equipment, finished product conveyors, checkweighers, metal detectors, cartoning machines, case packers, and other downstream packaging equipment. For heavier liquid packs, discharge handling and downstream conveying should be considered during line design.
Soontrue Group can help configure the packaging line according to product viscosity, filling weight, bag size, film structure, target speed, and factory layout. For products with particles, samples should be evaluated to confirm pump type, filling stability, and sealing performance.
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 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 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 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.
