Valve bags are the preferred choice for factory automation: no material leakage, high efficiency.
Foshan Hongyun Jiangtian Packaging Valve Bag Principle:
During filling, the valve flap opens → Material enters
After filling, the valve flap automatically closes → Sealed and leak-proof
Fully sealed throughout, dust-free, no waste.
Compatible with most automatic filling machines.
