Safety First: Understanding the SWL in Bulk Bags

A deep dive into Safe Working Load (SWL) testing for FIBC bags and why it matters for cargo safety.

Deciphering the SWL

Every FIBC Jumbo Bag carries a rating known as the Safe Working Load (SWL). But what does a 5:1 or 6:1 Safety Factor actually mean? It is the difference between a safe operation and a catastrophic failure.

The 5:1 Factor Explained

A 5:1 Safety Factor means that a bag rated for 1,000kg (SWL) must be able to withstand a static load of 5,000kg before failing. This massive overhead is designed to account for the dynamic forces experienced during transport, such as crane lifts and truck vibrations.
