Why Do Powder Chemical Companies Prefer Liner-Free Circular FIBC Bulk Bags?

In the powder chemical industry, ensuring safe and leak-proof transport of bulk materials is a top priority. Compared to traditional four-panel bag structures, circular FIBC bulk bags offer superior sealing and stability due to their seamless tubular body design. For fine and free-flowing powder chemicals, this design reduces the risk of powder leakage and moisture ingress significantly.

One of the main advantages of using liner-free circular bags is the simplification of the packing process and reduced overall cost. Especially in high-purity applications such as pharmaceutical ingredients, specialty chemicals, or paint additives, these FIBCs meet sealing standards without needing additional PE liners—avoiding the risk of contamination caused by liner rupture.

Moreover, these bulk bags are woven with high-strength virgin polypropylene yarn, offering a 5:1 safety ratio and excellent tensile and load-bearing capabilities. They can withstand frequent handling and stacking during transport, ensuring cargo safety and stability.

For chemical companies, choosing a liner-free circular big bag enhances packaging efficiency while improving logistics performance and cost-effectiveness.
