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 A PP woven bag can look perfectly fine when new but become brittle or crack weeks or months later during storage, transport, or handling. This usually happens because of environmental exposure, material quality, formulation, or prolonged storage. Understanding these causes helps buyers choose the right specification before a problem reaches the filling line, warehouse, or customer. This article explains the main reasons PP woven bags become brittle and how Formos

Introduction If your packaging bill keeps climbing even though your per-bag price hasn't changed, the price tag isn't the problem — the total cost is. Cheaper bags often shift cost from the invoice to somewhere less visible: product loss, rejected shipments, extra labor, and damaged relationships with your own customers. These costs rarely show up in a single line item, which is exactly why they go unnoticed until margins start shrinking for reasons that seem to have no clear

Introduction A torn bag during filling is one of the most frustrating problems on a packaging line — it stops production, wastes product, and creates a mess that costs time and money to clean up. Many buyers assume it's simply a "bad batch" of bags, but filling-stage tears almost always trace back to one of a handful of specific, fixable causes: fabric spec, machine settings, product characteristics, or handling. Understanding these causes helps you diagnose the real problem

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
