The load-bearing capacity of a bulk bag generally ranges from 500 kg to 3 tons. This capacity varies depending on the design, materials, and manufacturing process. For example, a lightweight bulk bag may have a load-bearing capacity of around 500 kg, while a heavy-duty bulk bag can hold up to 3 tons. Furthermore, the load-bearing capacity of the slings used to hold the bag is crucial: flat slings can support 1 to 20 tons, while round slings can support 1 to 200 tons.
