A durable and safe ton bag requires critical structural design.

Foshan Hongyun Jiangtian Packaging, drawing on 10 years of frontline production experience, informs you: A ton bag consists of five core components, each indispensable.

1. Bag body: The main load-bearing component, made of high-density polypropylene (PP) woven fabric.
2. Lift loops: The core load-bearing component, critical for safety.
3. Top opening: Open top, drawstring closure, spout, valve port.
4. Bottom discharge outlet: Flat bottom, discharge valve, butterfly valve.
5. Inner liner: Designed to prevent moisture ingress, leakage, and contamination.

Each structural component affects the ton bag’s service life and safety. All our ton bags undergo tensile, drop, and load tests.
