Types & Uses of FIBCs, Sizes & Volumes

FIBCs are constructed from a flat polypropylene (PP) fabric in several ways, can be either coated or uncoated and vary in weight depending on the Safe Working Load (SWL) or Safety Factor (SF) requirements.

  • U-Panel construction - made from 2 pieces of fabric with 2 seams along 2 opposite sides
    to create 2 panels into a “U” Panel shape.
  • Four panel bag (the original polypropylene design) - requires seams along four separate pieces of fabric
     sewn to create a four panel bag.
  • A Circular or Tubular bag made from fabric that has been woven into a cylinder or tube of fabric, cut to the
    correct size. This tubular body design is ideal as a liner-less option for fine materials.
  • Form-stable or Baffled bags with corner baffles sewn in to maintain their shape when they are filled, allowing
    the product material to flow into all corners of the bag.
  • Vented bags - A section of each side of the bag is vented to allow airflow throughout the contents of the bag, most suitable for use in the agriculture industry for fruit and vegetables such as potatoes.

FIBCs are also designed as either Single Trip bags (to be used for one filling and discharge only) or Multi Trip bags (which are reuseable, for multiple fillings and discharges).

There are generally 6 types of FIBCs:

Type A - no special electrostatic safety features; not to be used for combustible materials or utilised in flammable or combustible environments
Type B - as Type A but with an insulating fabric to prevent propagating brush discharges
Type C - conductive or groundable bulk bags or a conductive FIBC, must be electrically grounded during filling and emptying.
Type D - antistatic bulks bags; constructed from antistatic fabric which has antistatic or static dissipative properties and does not require grounding
Food Grade - manufactured to a food safety standard and certified by a food safety standard certifying body.
UN Certified - to handle products that the United Nations considers hazardous material (also referred to as UN DG - United Nations Dangerous Goods - bags).
