Woven Sacks & FIBC Explained — Types, Specifications & Safety | Packaging
Woven sacks and FIBC (jumbo / bulk bags) carry almost everything shipped in bulk — cement, food grains, sugar, chemicals, polymers, fertiliser and minerals. This short, no-jargon guide explains what they are and how to read their key specifications, using clear diagrams, sketches and animations (light music, no voice-over).
You'll see how woven PP/HDPE sacks are made and what GSM, picks, denier, lamination and load rating actually mean — then move to FIBC bulk bags: U-panel vs 4-panel vs circular vs baffle construction, top and bottom options, lifting loops, SWL and the 5:1 / 6:1 Safety Factor, and the static-protection Types A, B, C and D. It ends with a one-screen spec checklist you can use before you buy or quote.
