The global transition toward electrification, driven by the rapid growth of Electric Vehicles (EVs) and Energy Storage Systems (ESS), has triggered an unprecedented demand for high-purity raw materials such as Lithium Carbonate, Cobalt Hydroxide, Nickel Sulfate, and Graphite. As these materials are highly sensitive to moisture, contamination, and static electricity, the logistics industry has faced a significant challenge: how to transport thousands of tons of powder safely and efficiently across continents.
FIBCs (Flexible Intermediate Bulk Containers), specifically engineered for the "New Energy" sector, have become the gold standard. Unlike standard industrial bags, New Energy Raw Material Jumbo Bags must meet stringent clean-room standards to ensure that no foreign particles compromise the battery cell's integrity.
The industry is currently shifting toward three major trends:
With the rise of ultra-fine powders, the use of Type C (Conductive) and Type D (Dissipative) bags has become mandatory to prevent catastrophic dust explosions during filling and discharging.
Manufacturers are moving toward 100% recyclable polypropylene (PP) materials and exploring multi-trip FIBCs to reduce the carbon footprint of the EV supply chain.
Integrating RFID and QR code tracking into jumbo bags allows for real-time monitoring of raw material batches, ensuring quality control from the mine to the Gigafactory.
Founded in 1988, Yantai ZS Bulk Bags Manufacturing Co., Ltd. is a professional manufacturer specializing in the customized design and production of mid-to-high-end FIBCs. With over 30 years of dedication, we provide packaging solutions that carry trust and safeguard value for global customers.
Our two modern production bases in Yantai City cover 60,000 square meters, employing 300+ staff members, including 30+ technical specialists. We maintain a stable monthly output of over 250,000 units, totaling more than 3 million units annually.
For the new energy sector, we offer a Macro-Industry Solution that integrates customized bag design with the customer’s filling and discharging equipment. Our technical roadmap involves:
Testing bulk density and particle size of the raw material.
Determining the need for Aluminum Foil Liners or PE liners for moisture protection.
Utilizing Baffle Bag (Q-Bag) designs to maximize shipping container space.
Conducting UN Certification for hazardous material transport.
Our products are utilized in various high-stakes environments:
Our facility is equipped with advanced drawing, weaving, cutting, and printing machinery, ensuring a complete closed-loop industrial chain. Every ton bag undergoes rigorous quality inspection before dispatch.
As the "New Energy" market matures, Yantai ZS is committed to leading the technological shift toward Zero-Waste Packaging. We are currently researching bio-based polymers and modular FIBC designs that can be refurbished, further aligning our manufacturing with the environmental goals of our global partners. By choosing our custom solutions, you are not just buying a bag—you are investing in a 30-year legacy of engineering excellence and a sustainable future for the battery industry.
