Custom Liquid Filling & Packaging Systems
We engineer high-performance liquid packaging systems capable of handling a broad range of viscosities—from water-thin liquids to dense, high-viscosity gels and pastes.
Multi-Lane Pouch Systems
High-speed, multi-lane vertical form-fill-seal (VFFS) systems engineered for packaging single-serve liquid sachets and stick packs. Ideal for ketchup, cosmetic serums, shampoos, and nutritional gels with highly precise volume control.
Turnkey Production Lines
Fully integrated primary and secondary packaging lines. We combine liquid filling, sachet sealing, checkweighing, cartoning, and palletizing into a unified, PLC-controlled smart system to minimize labor costs and boost output.
B2B OEM Customization
Tailored machine design to match specific factory layouts, cleanroom standards, and unique liquid characteristics. We support custom nozzle profiles, anti-dripping mechanisms, CIP cleaning integration, and specialized film handling.

Operating as a premium Global Liquid Bag Filling Machine Manufacturer, Ludyway is dedicated to solving complex viscosity challenges. Our liquid systems integrate advanced servo-driven piston pumps, rotary lobe pumps, and flow meters to guarantee high-precision dosing with an accuracy tolerance of ≤±1%. This ensures minimal product giveaway across varied chemical, food, and pharmaceutical formulations.
Our machines are built with food-grade SUS304/SUS316L stainless steel contact parts to meet strict FDA, GMP, and CE certification standards. We also integrate clean-in-place (CIP) systems that allow swift sanitization between production runs, ensuring zero cross-contamination.
| Liquid Type | Viscosity Range | Filling Mechanism | Typical Applications |
|---|---|---|---|
| Thin Liquids | 1 – 100 cPs | Gravity / Flow Meter | Water, Juice, Alcohol, Solvents |
| Medium Viscosity | 100 – 5,000 cPs | Piston Pump | Shampoo, Oils, Lotions, Soy Sauce |
| High Viscosity / Pastes | 5,000 – 50,000+ cPs | Rotary Lobe / Augur Assist | Creams, Honey, Ketchup, Resins, Gels |

Frequently Asked Questions
Key insights into our liquid bag filling systems, configuration options, and global support services.
What types of liquids can your bag filling machines handle?
Our liquid bag filling machines are engineered to handle a wide range of liquids, including low-viscosity liquids (water, juice, alcohol, solvents), medium-viscosity liquids (shampoo, oils, sauces, cosmetics), and high-viscosity pastes or gels (creams, honey, ketchup, industrial resins). We configure specific pump systems (piston, rotary lobe, or peristaltic) based on your product’s viscosity.
Can I customize the bag size and sealing style on your machines?
Yes, we provide extensive custom options. Our machines support various pouch styles, including 3-side seal, 4-side seal, stick pack, stand-up pouch (doypack), and custom-shaped pouches. Pouch dimensions can be adjusted via the PLC interface and by changing the forming tube assemblies.
How do you ensure dosing accuracy during high-speed filling?
We achieve exceptional accuracy (≤±1%) by integrating high-precision servo motors to drive our piston pumps or rotary lobe systems. For specific pharmaceutical or chemical applications, we can also integrate flow meter dosing systems to ensure exact fill volumes regardless of temperature or viscosity fluctuations.
Do your liquid filling machines support Clean-in-Place (CIP) systems?
Absolutely. All our liquid filling machines are designed with sanitary principles in mind. They can be fully connected to your factory’s centralized CIP system. Alternatively, we can design independent cleaning loops to ensure quick, automated flushing of all contact parts between product changeovers.
What is the typical lead time and shipping process?
Standard machine models have a lead time of 30 to 45 days. For complex, custom-engineered turnkey lines, lead times range from 60 to 90 days. We provide complete sea freight packaging using heavy-duty, fumigated wooden cases to ensure safe transit to your facility.
What kind of after-sales technical support do you provide?
Ludyway offers comprehensive global support. This includes remote video installation guidance, 24/7 technical troubleshooting, and on-site commissioning by our factory-trained engineers. We also maintain a complete spare parts inventory to ensure fast dispatch and minimize downtime.
