In the high-stakes arena of global industrial transport, the tubular bulk bag (also known as the Circular FIBC) represents a pinnacle of structural integrity and cost-efficiency. Unlike traditional U-panel bags, tubular bags are woven as a seamless cylinder, eliminating vertical seams which are often the weakest points in a bulk container. This fundamental engineering advantage is why Yantai ZS Bulk Bags Manufacturing Co., Ltd., founded in 1988, has dedicated over 30 years to perfecting the customized design of mid-to-high-end FIBCs.
The macro-industrial landscape is currently undergoing a "Bulk Transformation." As companies shift away from small-scale 25kg bags towards ton-capacity FIBCs to reduce labor costs and carbon footprints, the demand for reliable tubular bulk bags factory and exporters has skyrocketed. These containers are not merely "sacks"; they are sophisticated logistics tools integrated with anti-static properties, moisture barriers, and UV protection to safeguard multi-million dollar cargo across continents.
Circular weaving eliminates side seams, providing superior resistance against pressure and seepage—ideal for fine powders like chemicals and minerals.
Adherence to ISO 9001, ISO 22000, and FDA standards ensures that our bags meet the rigorous safety protocols required by international customs.
Integrating lean management with automated quality inspection to maintain a stable monthly output of 250,000+ units with zero defect tolerance.

The future of Tubular Bulk Bags lies in the intersection of material science and digital traceability. As a leading exporter, Yantai ZS is currently implementing a tech roadmap that focuses on three core pillars:
Heavy-duty tubular bags with 2-ton capacity and UV resistance for copper concentrate and iron powder, designed to withstand harsh outdoor storage in Australia and South America.
Type C Conductive bags with grounding capabilities to prevent electrostatic discharge (ESD) in volatile environments, essential for chemical factories in Germany and the USA.
ISO 22000 certified cleanroom production for MSG, fertilizers, and pharmaceutical granules, ensuring zero contamination for the Asian and Middle Eastern markets.
We provide localized documentation support including UN Certification for dangerous goods, FDA Food Grade certificates for North America, and CE Marking for European industrial safety standards. Our international sales team provides bilingual support to navigate the complex regulatory frameworks of over 50 countries.
Founded in 1988, Yantai ZS Bulk Bags boasts strong strength, with two modern production bases located in Laishan and Muping Districts. Our closed-loop industrial chain ensures every bag leaving our factory undergoes strict disinfection, ensuring it is hygienic, dust-free, and free from any impurities.
