Frequently Asked Questions
Q. What are the main benefits of a quad-side seal bag compared to a 3-side seal bag?
A quad-side seal (4-side seal) sachet provides superior structural strength and uniform tension on all four edges, minimizing the risk of leakage. It is highly symmetrical, making it aesthetically appealing for premium retail products. Additionally, it offers a wider flat surface for printing and branding, and ensures a better hermetic barrier for sensitive products like pharmaceuticals and food ingredients.
Q. Can your machinery handle different types of product states simultaneously?
Yes, our multi-lane sachet systems can be equipped with specialized dosing modules. We offer auger fillers for powders, volumetric cups for free-flowing granules, and piston/peristaltic pumps for liquids and pastes. Our systems can also be custom-engineered for dual-chamber packaging (e.g., packaging powder in one compartment and liquid in another within the same sachet).
Q. How does Ludyway guarantee compliance with international food and pharmaceutical standards?
We construct all product contact parts from 304/316L stainless steel to comply with GMP and FDA sanitation standards. Our machinery is CE certified, featuring sanitary wiring, safety interlocks, and dust extraction ports. We provide full documentation support, including IQ/OQ validation protocols for pharmaceutical clients.
Q. What is the lead time for customized packaging lines, and do you offer installation?
Our standard lead time is 45 to 60 days depending on the level of customization. We provide comprehensive FAT (Factory Acceptance Testing) before shipment. Once the machine arrives at your facility, our engineering team is available for on-site commissioning, calibration, and staff training. We also offer online remote technical support 24/7.
