An FIBC can be as simple as an open top with a flat base used commonly within the building industry or as a high tech unit produced within a clean room production environment to be used within the food/pharmaceutical industries. Most importantly, each FIBC is manufactured to meet a customers' specific requirement. FIBC/Jumbo bags basically have a square or rectangular base. The bag sizes can vary on depending the purpose for which they will be used.
The standard four loop bags all types of bulk materials.
Form Stabilized Bag
These are FIBCS with inner construction of baffles sewn to the main fabric so that the bags retain shape after filling. From Stabilized bags ensure...
Saving in Space, Higher Stability after filling, and Retention of the rectangular shape
A Conical bag is shaped as a cone at the bottom. These types of FIBCs are especially suitable
to pack Tacky products which are not so free flowing eg. Clay, Slurries etc. The Conical design
provides a gradient for these materials to 'flow' towards the outlet spout.
Cross Corner / Tubular Bag
Cross Corner loop bag has loops stitched on the body of the main fabric.
These types of FIBCs are prepared when retaining the shape of the lifting loop becomes important. This type of FIBC design is especially popular for Tubular FIBCs.
Ventillated or Breathable bags are FIBCs where the fabric has breathable stripes. This is useful for products that breathe while packed, especially fruits and vegetables.
Type A Bag
Type A FIBCs are made of a fabric that does not have any protective properties against the build-up of static electricity.
You can use this type of FIBC for non-combustible materials in an environment where no flammable gases are present.
Type B Bag
These FIBCs, like type A, have no protective properties against the build-up of static electricity.
The difference is that the fabric material has a lower breakdown voltage (< 6 kV).
You can use this type of FIBC for dry, combustible materials, but there must not be any flammable gasses in the area.
Type C Bag
These FIBCs are made of a conductive fabric. The conductivity is obtained by interweaving several conductive yarns.
The various threads of yarn are connected to each other and come together at an earthing point. You must therefore earth this FIBC at all times.
You can use this type of FIBC for combustible materials and in environments where flammable gases are present.
Type D Bag
These FIBCs are made of a special anti-static fabric with permanent discharge properties (corona discharge).
They do not need to be earthed. However, it is crucial that the immediate vicinity (machinery, staff, etc.) is fully earthed.
There are also restrictions on the relative humidity in order to safely use this type.
