The bag is designed to withstand at least five times its rated safe working load (SWL) in a top-lift test before failing. A 1,000 kg SWL bag at 5:1 must survive 5,000 kg in the laboratory. 5:1 bags are intended for single use; 6:1 bags are rated for multiple trips when inspected between uses. ### Which FIBC is best for firewood? A vented (breathable) bulk bag with mesh side panels lets split logs dry and prevents mould. Typical sizes are 90×90×120 cm or 95×95×135 cm for about 1 m³ loose volume, with four side-seam or cross-corner loops for forklift handling. ### Can you add a liner or discharge spout? Yes. PE liners (sewn-in or loose), top filling spouts, bottom discharge spouts with closure flaps and dust-proof seams are all standard options. Tell us your product, bulk density and filling method and we will recommend a configuration. ### Are super sacks, bulk bags and FIBCs the same thing? Yes. Super sack, bulk bag, jumbo bag, big bag and ton bag are all common names for an FIBC (flexible intermediate bulk container) — a woven polypropylene bag that typically holds 500–2,000 kg and is lifted by its loops. ### What size bulk bag do I need? Divide the fill weight by the product's bulk density, add about 10% headroom and divide by the base area. Our free bulk bag calculator does it for you.
