The global construction industry is undergoing a paradigm shift in how bituminous materials are transported. Traditionally, asphalt and bitumen were shipped in heavy steel drums or expensive bulk tankers. However, the emergence of the Construction Asphalt Bulk Bag (often referred to as Bitubags) has revolutionized logistics, especially for remote infrastructure projects in Africa, Southeast Asia, and South America.
Modern asphalt bulk bags are designed to hold between 1,000kg to 1,500kg of cold-mix or specialized hot-pour asphalt. This shift is driven by the need for Information Gain in logistics efficiency—reducing "dead weight" packaging and enabling 20ft containers to carry significantly more payload compared to traditional methods.
Reduce logistics overhead by up to 30% compared to drum packaging. Our bags optimize space in sea freight and simplify site-level handling.
Engineered to withstand filling temperatures of up to 120°C, ensuring the integrity of the polymer-modified bitumen during the cooling phase.
Unlike non-degradable waste, our PP-based FIBCs are recyclable, aligning with global green building standards and ESG requirements.
The next decade of asphalt packaging is defined by Material Science. We are moving beyond simple woven polypropylene into multi-layered composite barriers.
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 have become a trusted choice for well-known global enterprises.
Our production base covers 60,000 square meters with a stable monthly output of over 250,000 units. We strictly control quality from raw material processing to finished products, ensuring every bag meets the rigorous demands of construction environments.
In regions like the Outback or Sub-Saharan Africa, asphalt bulk bags allow for easy transport via standard flatbed trucks without the need for specialized heating tankers until the final application.
Ideal for municipal road maintenance. Bags can be stored in local depots for months, providing a "ready-to-use" solution for pothole repairs during winter seasons.
Lightweight and durable, these bags are the only viable solution for transporting binding materials to mountain road projects where heavy tankers cannot navigate tight hairpins.
Extruding 100% virgin PP resins into high-tensile tapes.
Circular weaving for seamless structural integrity.
Ultrasonic cutting to prevent fraying and dust.
Dust-free workshop sewing to ISO 22000 standards.
We strictly comply with ISO 9001 and ISO 22000. Our asphalt bags undergo rigorous stress tests, including top-lift testing, stack testing, and UV degradation simulation. This ensures that when you choose ZS, you are choosing a partner that prioritizes Reliability and Safety above all else.
