B2B Technical FAQ
Get professional answers to technical and operational questions regarding our four-side seal sachet machines.
1. What are the main benefits of a 4-side sealing machine?
A 4-side seal provides a completely flat, rectangular pouch with high aesthetic appeal and maximum sealing integrity. It is ideal for fine powders, liquids, and pastes where leakage prevention is critical. It also allows for clear printing on both the front and back of the sachet.
2. Can one machine handle both powder and liquid products?
Yes, by utilizing interchangeable dosing systems (such as auger fillers for powder and piston pumps for liquid) on a modular base, the machine can be converted to handle different textures. We offer quick-release modules to reduce changeover times.
3. What packaging materials are compatible with Ludyway machines?
Our machines are designed to run a wide range of heat-sealable laminated films, such as PET/AL/PE, OPP/PE, Nylon/PE, and eco-friendly recyclable barrier papers. Film tension is controlled automatically via servo motors.
4. How is filling accuracy maintained across multiple lanes?
Each lane is equipped with independent dosing components (e.g., individual auger screws or piston cylinders) that are controlled via a central PLC system. This ensures that every lane delivers the exact same volume, maintaining accuracy within ±1%.
5. What is the typical lead time and installation process?
Standard machine models have a lead time of 30-45 days. Customized turnkey production lines require 60-75 days. We provide complete FAT (Factory Acceptance Testing) videos, detailed manuals, and dispatch engineers for on-site commissioning and staff training.
6. How does the machine handle dust control for fine powders?
Our powder packaging machines are equipped with integrated dust extraction nozzles at the filling station. This keeps the sealing area clean, ensures strong seal bounds, and maintains a clean working environment in compliance with GMP standards.
