Introduction A full FIBC bulk bag can weigh over a tonne, and it's often lifted well above ground or dock level — which means a lifting failure isn't just a packaging problem, it's a safety incident waiting to happen. Most failures come down to one thing being ignored or misunderstood: Safe Working Load (SWL). At Formosa Synthetics, every FIBC bag we manufacture — from 500 kg to 2000 kg SWL, with a 5:1 or 6:1 safety factor — is built around this principle from the raw materia

Introduction Bags that arrive firm and well-formed but slump, bulge, or collapse once stacked create problems far beyond appearance — they waste pallet and container space, increase the risk of toppling, and can put pressure on lower bags until they fail. This is a different problem from tearing or brittleness: the fabric isn't necessarily damaged, but the bag can't hold its form under sustained load. The causes are usually predictable once you know what to look for. This blo
