Our Heritage & Manufacturing Capacity
The Ludyway Story
Founded in 2010, Ludyway Machinery started with a clear vision: to deliver highly efficient, reliable, and automated packaging solutions to global manufacturers. Beginning as a small, focused engineering group specializing in custom liquid dosing and pouch sealing technology, the company expanded rapidly by prioritizing robust mechanical designs and customer-centric integration.
Today, Ludyway stands as a global player, utilizing state-of-the-art tooling, CNC machining centers, and raw materials testing to fabricate packaging lines that operate continuously in demanding environments. Our focus on long-term cooperation drives us to offer unparalleled service, from initial project design to life-cycle technical support.
Milestones & Growth
Since initiating our international business division in 2010, we have systematically expanded our product portfolio. By addressing the global shift toward automation, we developed complete turnkey production lines incorporating cartoning systems, checkweighers, and case pack packers alongside our liquid sachet machinery.
Our 20,000㎡ modern manufacturing facility in China acts as the hub of our innovation. It houses advanced testing rooms where customers can send liquid samples for viscosity testing and trial runs, ensuring the selected machine configuration meets their exact target parameters prior to shipment.
International Quality Certificates
Ludyway packaging machines conform to strict international standards. Our manufacturing processes are audited annually to ensure safety, reliability, and precision engineering.

Liquid Sachet Filling Equipment FAQs
How do you ensure zero leakage during high-speed liquid packaging?
We employ specialized anti-drip and suck-back nozzle systems combined with precise pneumatic or servo-driven shut-off valves. This ensures that no liquid residues adhere to the sealing zone of the film, allowing the horizontal and vertical seal bars to achieve hermetic, leak-free seals even at high operating speeds.
Can one liquid sachet filling machine handle different types of products?
Yes. Our machines are designed with modular dosing systems. By swapping the pump type (e.g., piston pump for viscous pastes or magnetic pump for free-flowing liquids) and adjusting nozzle configurations, you can package different products on the same base machine. Adjustments are easily configured using the PLC touch screen.
What packaging materials are compatible with your sachet equipment?
Our equipment supports a wide variety of heat-sealable laminated films, including PET/AL/PE, PET/PE, Paper/PE, Nylon/PE, and biodegradable barrier films. The temperature of the sealing jaws is individually controlled for vertical and horizontal seals to accommodate varying film thicknesses.
How is cleaning and sanitation handled for food and pharma applications?
All contact parts are constructed from SUS316L stainless steel, meeting strict GMP and FDA requirements. The dosing pumps and pipelines are designed for quick disassembly, allowing for manual cleaning, or they can be integrated with a CIP (Clean-in-Place) system for automated, sanitary washdowns.
What is the typical lead time and global support process?
Standard machines have a lead time of 30–45 days, while customized high-speed multi-lane packaging lines require 60 days. We offer comprehensive global support, including FAT (Factory Acceptance Testing) video verification, on-site commissioning by our engineers, and 24/7 remote technical assistance.
