TYPES & USES of FIBCs
U-PANEL BAGS Two piece, U-Panel construction that has two seams sewn along the two opposite sides to create two panels, creating a “U” Panel shape. Accepted as the industry standard around the world, the U-Panel FIBC is the most popular FIBC shape. This construction gives the bag a large lifting capacity.
FOUR-PANEL BAGS It is the original polypropylene design, Four-Panel Bulk Bags (FIBCs) have seams along four separate pieces of fabric that are sewn together to construct the body of the bag as well as having the top and bottom panels sewn in. Four-Panel bags tend to hold their shape better than other types of bags and are better suited for stacking.
CIRCULAR WOVEN BAGS A Circular or Tubular bag is woven into a cylinder or tube and cut to the correct size. The most common construction type is a circular fabric on the body with a sewn square base. As there are no seams in this construction, this creates for a more aesthetically pleasing bag, and with only a top and bottom panel sewn into the bag, they are ideal for fine and hydroscopic materials. The tubular body design is also ideal as a liner-less option for fine materials and is recognized for its ease of lifting and manipulating with a forklift.
CONICAL BAGS The Conical Bag is designed specifically to assist in the complete discharge of contents, which are slightly sticky, like brown sugar and premix flour products. The conical shape at the bottom of the bag ensures that the bulk bag can be discharged quickly and easily.
FORM-STABLE or BAFFLE BAGS This special Baffle construction offers maximum stability to the bag. There are 4 baffles sewn to the main fabric at each corner to prevent bulging of bag when filled, allowing for a more effective use of the bag’s storage capacity. Four rigid cross corner loops allow the forklift operator to pick up bags without the requirement of additional staff. The Baffle Bag is ideal for light-density products and can be more economical as it increases payload - the larger panel width allows corners to be filled with 25%-30% more product. Another advantage is the increased stackability and with all sewn edges turned to the outside, it reduces potential of contamination.
TYPE B Type B Bulk Bags are very similar to the Type A bags as they are made from the standard polypropylene material, they too do not have the ability to dissipate static electricity efficiently. The difference is that the material used is an insulating fabric but this has a low breakdown voltage (less than 4KV) to prevent propagating brush discharges (PBD) which are highly energetic and dangerous. Type B bags can prevent PBD, however normal brush charges can still occur so these bags cannot be considered to be antistatic in any way. Type B bags may be used in the presence of the combustible dusts with MIE of greater than 3mj but in the absence of flammable vapors of gases. • Used to safely transport dry, flammable powders, • There are to be no flammable solvents or gases present around the bag, • DO NOT USE to transport flammable products.
TYPE C Type C Bulk Bags known within the industry as conductive or ground able Bulk Bags or conductive FIBCs. Constructed from non conductive polypropylene material interwoven with conductive yarns that form a grid pattern, these are designed to control electrostatic charges by grounding. The bag MUST be electrically grounded during filling and emptying - this is essential to the safe use and performance of a Type C bag. • Used safely to transport flammable powders, • Used safely when flammable solvents or gases are present around the bag, • DO NOT USE when ground connection is not present or has become damaged.
FOOD GRADE Food grade bags are bags that are made with the intent of putting food products into the bags. A Bulk Bag that is manufactured in a facility that has undergone an audit and is certified by a food safety standard.

Bulk Bags are classified according to one of four Types: A, B, C and D. All these Types are defined by the construction of the Bulk Bags, the intended use and performance requirement criteria.
TYPE A Type A Bulk Bags are made from standard polypropylene material which is a non-treated insulating fabric. They have no special electrostatic safety features. Static electricity is generated as products move over the inside surface of the Bulk Bag when they are being filled or discharged. As there is no static protection provided by Type A Bulk Bags, these are not to be used for combustible materials or utilised in flammable or combustible environments.
No requirements are specified for Type A FIBCs as they are not intended for use in potentially explosive atmospheres. • No static protection, • Used safely to transport non-flammable products, • There are to be no flammable solvents or gases present around the bag, • DO NOT USE to transport flammable products.
Type D Bulk Bags are also called antistatic Bulks Bags. A type D bag is constructed from antistatic fabric which has antistatic or static dissipative properties to safely prevent the occurrence of incendiary sparks, brush discharges and propagating brush discharges and does not require grounding. • Used safely to transport flammable powders, • Used safely when flammable solvents or gases are present around the bag, • DO NOT USE when the surface is contaminated or coated with conductive material such as water or grease.
UNITED NATIONS CERTIFIED FIBCs These bags are designed to handle products that the United Nations considers hazardous material. The international transport of dangerous goods in Bulk Bags is regulated by a number of international codes based on the United Nations Recommendations on the Transport of Dangerous Goods (also known as the Orange Book). This divides bulk containers into 6 categories namely: metal, flexible, rigid plastics, composite, fibreboard and wooden.
There are four types of FIBCs made from woven polypropylene for dangerous goods:
1) 13 H 1 - Woven plastics without coating and without liner,
2) 13 H 2 - Woven plastics, coated and without liner,
3) 13 H 3 - Woven plastics, uncoated and with liner,
4) 13 H 4 - Woven plastics, coated and with liner.
