Asphalt (bitumen) is traditionally filled at temperatures exceeding 150°C. Standard polypropylene (PP) bags melt or lose structural integrity at these heat levels. Our specialized High-Temperature FIBCs utilize advanced heat-stabilized polymers and high-barrier aluminum foil liners to withstand the molten state of bitumen, ensuring safe cooling and leak-proof transportation.
Leveraging 30+ years of manufacturing expertise, Yantai ZS Bulk Bags integrates heat-resistant additives directly into the weaving process. Our bags are not just "heat-resistant"; they are engineered with a safety factor of 5:1 or 6:1, certified under ISO 9001 and ISO 22000, ensuring every bag provides the structural authority needed for hazardous material handling.
Compared to steel drums, FIBCs offer a significant reduction in carbon footprint. They are lighter, collapsible when empty, and more cost-effective for global shipping. Our bags are designed for 100% recyclability, meeting modern ESG (Environmental, Social, and Governance) requirements for the global mining and road construction sectors.
Integrated Supply Chain: Factories like ZS Bulk Bags manage everything from raw resin drawing to ultrasonic cutting. This closed-loop system reduces contamination risks and ensures that heat-stabilizing formulas are consistent across every batch.
Technical Customization (ODM/OEM): Chinese manufacturing has evolved from volume-based to value-based. We offer customized baffle designs, discharge spout configurations, and anti-static (Type C) properties to meet the unique needs of hot-fill operations.
Cost-Efficiency at Scale: With a monthly output of over 250,000 units, our Laishan and Muping bases provide economies of scale that European or American manufacturers cannot match without compromising on the specialized manual sewing required for high-quality FIBCs.
The global asphalt logistics industry is rapidly moving away from 200kg steel drums. The "Big Bag" (FIBC) allows for 1,000kg to 1,500kg per unit, drastically improving loading times by up to 400% and reducing empty container return costs.
Modern high-temperature bags now incorporate multi-layer co-extruded liners with aluminum foil. This prevents the bitumen from bonding with the outer PP fabric and provides a superior oxygen barrier to prevent oxidation of the chemical contents.
With the expansion of the "Belt and Road" initiative and global post-pandemic infrastructure projects, the demand for portable, high-capacity asphalt packaging has spiked in Central Asia, Africa, and Southeast Asia.
Founded in 1988, Yantai ZS Bulk Bags Manufacturing Co., Ltd. uses a professional manufacturer's approach to customized mid-to-high-end FIBCs.
For large-scale infrastructure and chemical enterprises, procurement isn't just about buying a bag; it's about solving a logistics bottleneck. ZS Bulk Bags provides comprehensive solutions:
Designed for low-temperature crack resistance while maintaining high-temperature filling capabilities. Ideal for Russia, Canada, and Northern Europe.
Enhanced UV resistance for long-term outdoor storage in the Middle East and Australia, preventing bag degradation under intense solar radiation.
Leak-proof and moisture-resistant liners for high-value graphite, fertilizers, and hazardous chemicals, ensuring zero loss during transshipment.




We strictly comply with ISO 9001 and ISO 22000 standards, ensuring our products are safe for everything from mining concentrates to pharmaceutical-grade powders.
With over 3 million units produced annually and a commitment to 100% virgin materials, ZS Bulk Bags is your premier choice for high-temperature and industrial FIBC solutions. Contact us for a quote or custom design consultation today.
