There's a class of packaging that never gets lifted by hand at all. Bulk material moved by the ton, from mined minerals to plastic resin, needs a container a forklift or crane can lift in a single pass. That's where heavy-duty woven bags and FIBC jumbo bags work, and their class is well above an ordinary 50 kg rice sack. This page is about the heavy-duty woven material itself. For full production see custom sack printing.
A Different Load Class
Ordinary PP woven sacks are built for 5-50 kg that a person can still lift. Heavy-duty woven bags, especially FIBC (Flexible Intermediate Bulk Container) jumbo bags, work in the 500-1,000 kg class per fill. That load difference changes the entire construction.
The weave is far thicker and tighter to hold hundreds of kilos without stretching or tearing. Seams are reinforced at the points that carry the most load. The biggest difference is the lifting loops at the four top corners, the path where forklift tines or crane hooks enter to lift the whole full bag. These loops are load-tested so they don't snap when lifted at maximum.
Capacity, Dimensions, and Construction
FIBC jumbo bags typically hold 500-1,000 kg with dimensions around 90x90x110 cm, though the size can be matched to material density and storage height at your site. Dense material like minerals needs a smaller but stronger bag, while light bulk material can use a larger one.
Several construction options set how easy handling is. A top filling spout speeds loading from a silo or hopper. A bottom discharge spout makes pouring out material easy without flipping the whole bag. The loop type can be matched: four separate loops for a forklift, or a single central loop for a crane. Tell us how you handle them on site so we pick the right configuration.
Suitable Materials
Heavy-duty woven bags are used for heavy bulk materials moved by the ton, not retail sacks. Minerals and mining output, aggregate, sand, factory bulk sugar, plastic resin, powdered chemicals, and industrial raw materials. One jumbo bag replaces dozens of small sacks, so loading and unloading is far faster and labor is leaner.
For moisture-sensitive material we add an inner liner. For hazardous material, we make sure the construction and labeling follow the applicable handling standard, including the symbols and safety information that must appear.
Printing and Labeling
We print the company logo, material name, safe working load (SWL), and batch code on the bag side. SWL matters because forklift and crane operators need to know the load limit they can lift. For hazardous material we include the symbols and warnings to standard. The print is chosen to stay legible even when the bag surface is coated with bulk-material dust that builds up during use.
Pricing Logic
Heavy-duty woven bags cost more per unit than ordinary sacks because they use more material and more complex construction, but the cost per kilo of material moved is actually lower since one bag carries a large load. MOQ depends on the construction type and loop features chosen. We send final pricing after capacity, dimension, loop type, and inner specs are complete.
For lighter load needs, compare with the base PP woven material for 5-50 kg sacks. For bulk feed material that needs stacking strength but not jumbo class, see animal feed sacks.
