YL400A Liquid Vertical Packaging Machine
YL400A
YL400A Liquid Vertical Packaging Machine Typical Applications
- Dairy products: milk, yogurt, cream.
- Beverages: juices, flavored drinks, soy milk.
- Sauces & condiments: ketchup, mayonnaise, chili sauce, soy sauce.
- Cooking oil: edible oil, olive oil, sesame oil.
- Personal care & chemicals: shampoo, liquid soap, detergent, lubricants.
The YL400A is a Vertical Form-Fill-Seal (VFFS) machine specifically engineered for packaging liquids and pastes. It automatically forms pouches from film rolls, fills them with precise volumes of liquid, and seals them securely, ensuring leak-proof and hygienic packaging.
The machine is compatible with different viscosity levels — from free-flowing beverages like juice to thicker pastes such as sauces or creams — thanks to its customizable filling systems (piston pumps, peristaltic pumps, or gravity filling). Its servo-driven controls ensure dosing accuracy and consistent sealing quality.
The YL400A is a reliable choice for manufacturers seeking high-speed liquid packaging, reduced product waste, and compliance with hygiene standards.

Competitive Advantage
- Liquid-Specific Engineering：While many vertical machines are adapted from dry product packers, the YL400A is purpose-built for liquids, ensuring better dosing precision and sealing reliability.
- Superior Seal Integrity：Competitor machines often struggle with seal contamination when packing sauces or oils; the YL400A’s anti-drip filling nozzles and precise sealing system prevent leaks and weak seals.
- Reduced Downtime：Quick disassembly of liquid contact parts and CIP compatibility mean faster cleaning cycles compared with traditional liquid packers.
- Versatility Without Extra Cost：One machine can pack both thin liquids and thick pastes without requiring additional dedicated equipment, lowering investment costs.
- Higher ROI：By minimizing spillage, rejects, and product loss, buyers see faster payback periods compared with generic liquid VFFS models.
- Proven Track Record：Soontrue machines are widely used in dairy, beverage, and condiment industries, providing reliable performance and stable supply for high-demand buyers.
