Transporting hot asphalt (bitumen) requires packaging that can withstand temperatures exceeding 150°C to 180°C without structural failure. Standard bulk bags melt or weaken, leading to catastrophic leaks. Our bags use specialized heat-stabilized polypropylene and proprietary inner liners to ensure safety.
Beyond the initial pricelist, our solutions focus on reducing labor costs. By enabling bulk handling of asphalt instead of traditional small-scale metal drums, contractors save up to 40% in logistics and heating costs during site deployment.
Modern road construction emphasizes the circular economy. Our FIBC bags are designed for durability and recyclability, meeting global sustainability standards while preventing soil contamination from bitumen leakage during remote mountain road projects.
Founded in 1988: 30+ Years of Manufacturing Excellence.
Yantai ZS Bulk Bags Manufacturing Co., Ltd. is a global leader in customized FIBC design. With two modern production bases covering 60,000 square meters, we integrate the entire value chain—from raw material extrusion to ultrasonic cutting and dust-free sewing. Our focus on Hot Asphalt Transport Bags has made us a preferred partner for international infrastructure groups.
We leverage ISO 22000 and ISO 9001 certifications to ensure every bag meets rigorous safety factors (5:1/6:1). Our monthly output exceeds 250,000 units, catering to both emergency road repair supplies and large-scale highway tenders.
Unlike regional distributors, China-based factories like ZS Bulk Bags control everything from resin procurement to the final tensile test. This ensures that the high-temperature additives are perfectly blended into the yarn, not just coated on the surface.
In the infrastructure sector, project specs change rapidly. Our in-house design team can finalize a 1.5-ton anti-leak bitumen bag prototype within 48 hours, significantly faster than Western competitors.
Located in Yantai, our proximity to major shipping ports reduces transit times and export costs, keeping our global pricelist highly competitive even with fluctuating shipping rates.
In regions like Central Asia or Sub-Saharan Africa where bitumen heating plants are sparse, our bags allow for the transport of "Cold-Mix" or "Warm-Mix" asphalt over long distances without moisture ingress, thanks to our Moisture-Shield technology.
Beyond roads, hot-melt bitumen is essential for roofing. Our smaller 300kg to 500kg FIBCs with laminated liners are perfect for high-rise construction sites where space and crane capacity are limited.
Transporting hazardous granules or high-temperature industrial resins. Our Type C Conductive FIBCs prevent static discharge while handling flammable bitumen derivatives.
We use 100% Virgin PP with heat-resistant polymers. This is the foundation of a bag that won't degrade under UV exposure or extreme thermal stress.
High-tensile strength looms create a fabric density that prevents "bag bulge," ensuring the asphalt remains stable during sea freight stackage.
Eliminating fraying and contamination. For food-grade or high-purity industrial needs, this is non-negotiable for maintaining material integrity.
Every batch of our 1.5-ton bags undergoes a 5x or 6x safety factor test. We simulate real-world drop tests to ensure zero leakage upon impact.
