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 Most procurement teams treat GSM (Grams per Square Metre) as the final word on bag strength. You specify the GSM, your supplier confirms it, the bags arrive matching the number on paper — and yet they still tear, stretch, or burst during filling, stacking, or transit. If this sounds familiar, you're not alone, and it usually isn't a case of your supplier cheating you. It's that GSM measures fabric weight, not fabric performance. Two bags can carry the exact same

If you have ever ordered woven bags and later found them tearing, stretching, or failing under load, the real problem probably wasn't the supplier — it was the GSM. GSM, or Grams per Square Metre, tells you exactly how much fabric weight is packed into every bag. It is the single most important number that decides a bag's strength, durability, and cost, yet most buyers never ask about it. Whether you're sourcing PP woven bags for cement, fertilizers, grains, or industrial goo

When sourcing industrial packaging, most procurement teams focus on price. But one specification determines whether your shipment arrives intact: GSM (Grams per Square Meter). GSM measures fabric weight per square meter and is the most reliable indicator of bag durability and cost of ownership. A bag that fails mid-supply chain costs far more than the product loss—it damages customer relationships and your reputation. This guide explains what GSM means, why it matters more th
