In the global industrial landscape, the demand for Flexible Intermediate Bulk Containers (FIBC), commonly known as jumbo bags or ton bags, has evolved beyond simple storage. Modern logistics require high-integrity packaging that guarantees safety, contamination-free delivery, and electrostatic protection.
Yantai ZS Bulk Bags Manufacturing Co., Ltd., established in 1988, stands at the pinnacle of this evolution. With over 30 years of specialized experience, we represent the standard of Chinese manufacturing excellence, integrating advanced material science with rigorous quality protocols.

Customized high-tensile bags for copper concentrate, iron ore, and minerals. Features UV resistance and heavy-duty reinforced loops for extreme environment handling.
Type B & C Conductive FIBCs designed to prevent electrostatic discharge. Vital for fine powders and volatile chemical compounds.
Manufactured in ISO 22000 dust-free workshops. Ideal for MSG, wheat, corn, and sugar, ensuring zero contamination from source to destination.
As the "Circular Economy" becomes the global standard, jumbo bag manufacturing is shifting toward Sustainable Packaging and Smart Logistics. At ZS Bulk Bags, our technical roadmap focuses on three core pillars:
Research into rPP (Recycled Polypropylene) blends that maintain the 5:1 or 6:1 Safety Factor (SF) while reducing carbon footprint by 30%.
Integrating RFID and NFC tags into the bag loops to allow real-time inventory tracking and batch traceability for pharmaceutical clients.
Developing multi-layer co-extruded liners with nano-barriers to prevent oxygen and moisture ingress for highly sensitive ingredients.
Precision filament extrusion
High-speed circular looms
Automated ultrasonic cutting
Reinforced double-stitching
Moisture-barrier insertion
Load & stress testing
Global logistics ready
Navigating international shipping regulations requires a manufacturer that understands the nuances of local markets. Our products are engineered to meet:
"We provide 24/7 technical support for our global procurement partners, offering onsite bag performance audits and customization consultations."
A: We manufacture bags with a Safe Working Load (SWL) ranging from 500kg up to 3,000kg, with Safety Factors of 5:1 (single-trip) or 6:1 (multi-trip).
A: Our food-grade bags are produced in a Class 100,000 cleanroom using 100% virgin PP. We utilize ultrasonic cutting to prevent fraying and every bag undergoes internal vacuum cleaning and metal detection.
A: Yes. Our Type C bags feature interconnected conductive threads and must be grounded during filling and discharging to eliminate static electricity risks.
A: For standard configurations, we deliver within 15-20 days. Custom-engineered solutions typically require 25-30 days from design approval.
