In the high-stakes world of industrial bulk handling, particularly where volatile powders, chemicals, and granules are concerned, the risk of Electrostatic Discharge (ESD) is not just a technical challenge—it is a critical safety imperative. As a premier ODM Type C FIBC bags supplier, Yantai ZS Bulk Bags Manufacturing Co., Ltd. has spent over 30 years perfecting the intersection of material science and logistics safety.
Founded in 1988, our journey began with a vision to redefine the structural integrity of Flexible Intermediate Bulk Containers. Today, operating across 60,000 square meters of modern production space in Yantai, China, we produce over 3 million units annually. Our expertise in Type C (Conductive) FIBCs is rooted in deep R&D, ensuring each bag meets the rigorous IEC 61340-4-4 international standards for electrostatic safety.
Type C bags are constructed from non-conductive polypropylene fabrics interweaved with conducting threads, usually in a grid pattern. These threads must be electrically connected and grounded during filling and emptying. Our ODM solutions ensure a resistance to ground of less than 1.0 x 10^8 Ohms.
Our Yantai facility leverages China's complete industrial supply chain. From high-tenacity carbon filament sourcing to ultrasonic cutting technology, we offer a 30% efficiency gain compared to Western counterparts without compromising on E-E-A-T standards. We provide full traceability from resin to the final stitch.
With the rise of the EV industry, our Battery Material FIBCs have become industry benchmarks. Handling ultra-fine powders like lithium cobalt oxide requires zero-contamination and zero-static environments, which our ISO-certified cleanrooms provide.
For global chemical conglomerates, packaging is more than a container; it's a link in a highly regulated supply chain. Our Type C FIBCs serve as a macro solution for:
How we solve specific regional challenges:
As we move towards Industry 4.0, the FIBC industry is undergoing a digital and sustainable transformation. At Yantai ZS, we are integrating Information Gain into our product lifecycle:
Transforming raw virgin PP into high-tenacity tape.
