The global transition to electric vehicles (EVs) and renewable energy storage has catapulted the demand for high-performance lithium-ion battery separators. As a critical component that prevents short circuits while allowing ionic transport, the integrity of the separator material is paramount. However, the raw materials—often ultra-fine powders or specialized resins—are highly sensitive to moisture, static electricity, and particulate contamination. This is where ODM lithium-ion battery separator bulk bags (FIBCs) become an indispensable asset.
Separator materials require a "Class A" cleanliness environment. Our bags utilize ultrasonic cutting technology to prevent fiber fraying, ensuring that not a single loose thread compromises your battery chemistry.
Lithium-ion materials are notoriously hygroscopic. Our specialized aluminum foil liners and multi-layer co-extruded films provide an industry-leading Water Vapor Transmission Rate (WVTR) to keep contents bone-dry.
Handling fine powders often generates static. We supply Type C Conductive FIBCs and Type D Dissipative bags to prevent incendiary discharges in hazardous zones.
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 cost-effective customized solutions as our core. Relying on solid technical accumulation and strict quality control, we have become a trusted choice for well-known enterprises globally.
Our production bases in Yantai cover 60,000 square meters, maintaining a stable monthly output of over 250,000 units. We strictly control quality from raw material processing to finished products in a closed-loop industrial chain.
Navigating international trade requires more than just a good product; it requires adherence to rigorous safety and environmental standards.
We provide localized consulting for large-scale procurement in Europe, North America, and Southeast Asia. Our team understands the specific palletization and warehouse automation requirements (AGVs) of global battery gigafactories.
Leveraging China's dominant position in the battery value chain, we offer direct factory-to-port logistics, reducing lead times and ensuring price stability against global market fluctuations.

Cleanroom Production: For battery separator applications, all sewing processes are completed in a dust-free workshop that meets ISO 22000 standards. We use 100% virgin polypropylene and ultrasonic cutting to eliminate contamination. Every bag undergoes strict disinfection before packaging.
The move toward "Green Gigafactories" is driving demand for recyclable FIBCs. We are developing mono-material solutions that simplify the recycling process without compromising the barrier properties needed for lithium-ion components.
Modern battery manufacturing is highly automated. Our Baffle Bags (Q-Bags) are designed to maintain a square shape, maximizing container utilization by up to 25% and ensuring compatibility with automated discharge systems.
As separator materials become more specialized and volatile, the requirement for permanent anti-static properties (that don't wear off with humidity) is becoming the standard for top-tier suppliers.
Battery grade refers to a combination of high-cleanliness (dust-free production), moisture barrier excellence (often using aluminum liners), and electrostatic safety (Type C/D). It ensures that the separator or cathode/anode material is not contaminated by particles that could cause battery failure.
We use ultrasonic cutting to seal fabric edges, preventing loose yarns. Furthermore, bags are manufactured in a controlled cleanroom environment and cleaned with high-pressure air before vacuum packing.
Yes. We offer full ODM services where our engineers design the bag based on your material density, filling/discharge equipment, and transport conditions. Quotes are typically provided within 24 hours of technical confirmation.
Aluminum foil offers the highest oxygen and moisture barrier among all flexible packaging. For lithium-ion materials sensitive to even trace amounts of humidity, it is the gold standard for long-term storage and international shipping.
While we handle large-scale gigafactory supply chains, our flexible production lines allow for specialized custom runs to support R&D and pilot plant operations.
