Frequently Asked Questions
Q: What is the primary advantage of circular woven fabric over U-panel bags?
Circular woven fabric eliminates vertical seams in the body, significantly reducing the risk of bursting under heavy pressure and providing a more uniform shape.
Q: Can Circular Big Bags be customized for food-grade materials?
Yes, we use 100% virgin PP resin and clean-room manufacturing processes to ensure our bags meet strict food-grade hygiene standards.
Q: How do you ensure the bags can withstand UV exposure?
We integrate high-quality UV stabilizers into the PP resin during the extrusion process, preventing the fabric from becoming brittle when exposed to sunlight.
Q: What is the typical Safe Working Load (SWL) for these bags?
Depending on the fabric GSM and construction, our circular big bags typically range from 500kg to 2000kg SWL with a standard 5:1 safety factor.
Q: Are these bags recyclable?
Yes, polypropylene (PP) is a thermoplastic polymer that is fully recyclable, supporting your company's sustainability and ESG goals.
Q: Can I add a PE liner to prevent powder leakage?
Absolutely. We offer various PE liner thicknesses and styles to ensure a completely airtight and moisture-proof seal for fine powders.
