Advanced Liquid Packaging Technology
At Ludyway, we engineer our liquid sachet filling equipment with high-precision dosing systems that handle varying viscosities, from free-flowing liquids like water and alcohol to highly viscous pastes like gels, honey, and heavy lubricants. Our machines utilize modern automation to ensure drip-free cutoff and hermetically sealed edges.
- Piston Pump Dosing: Ideal for high-viscosity pastes and creams, ensuring ±1% filling accuracy.
- Peristaltic Pump Dosing: Perfect for pharmaceutical and cosmetic liquids requiring sterile paths.
- Rotary Valve Cutoff: Prevents stringing and dripping of sticky liquids at high production speeds.
- Multi-Lane Synchronous Sealing: Delivers uniform heat distribution across all lanes for leak-proof sachets.
Our systems feature user-friendly HMI touchscreens, allowing operators to adjust fill volume, sealing temperature, and cutter configuration on the fly. This flexible interface reduces changeover times from hours to minutes.

B2B Procurement Guide & FAQs
What is the typical lead time for custom liquid sachet machines?
For our standard multi-lane liquid sachet packing machines, the manufacturing lead time is 30 to 45 days. For highly customized turnkey packaging lines requiring integrated cartoning or custom dosing pumps, lead times range from 60 to 75 days. Factory Acceptance Testing (FAT) is conducted before shipment.
How do you ensure filling accuracy for different liquid viscosities?
We configure each machine with a specific dosing mechanism. High-viscosity pastes utilize servo-driven rotary valves and piston pumps to prevent dripping. Free-flowing liquids use gravity or magnetic flow meters. This tailored engineering guarantees a filling tolerance within ±1%.
Can your machines handle multi-component liquid filling?
Yes, we design dual-dosing systems that allow you to fill two different liquids (such as oil and water, or dual-flavored sauces) into a single sachet, either mixed or in separate chambers. This configuration is widely used in the food and cosmetic industries.
What after-sales and installation services do you provide?
Ludyway offers comprehensive global technical support. We provide detailed video instruction manuals, remote PLC troubleshooting, and online engineering consultations. For complex lines, we can dispatch field engineers to your facility for installation, commissioning, and staff training.
What packaging film materials are compatible with your equipment?
Our heating jaws are compatible with virtually all standard heat-sealable laminated films, including PET/AL/PE, PET/PE, Paper/PE, and Nylon/PE. We can adjust the sealing profile (smooth, diamond pattern, or vertical lines) based on your chosen film thickness and material properties.
Do you assist with testing film materials before purchasing?
Absolutely. We encourage clients to send their packaging film and liquid samples to our facility in China. Our engineering team will run test runs, optimize the sealing parameters, and send you video confirmation of the sachet quality before finalizing the order.
