DIFFERENT TYPE OF FIBCs

At PT. Wiharta Karya Agung or known as “wicon” brand, we understand your packaging needs and specialize in four specific types of FIBC bags universally labeled as Type A, B, C or D, which differ on their electrostatic properties and grounding requirements.

Type A FIBC / Bulk Bag (no electrostatic protection).

Type A bulk bags are basic, all-purpose bags that are made of plain-woven polypropylene. These FIBC bags do not offer static protection and are only used to safely transfer non-flammable products. Flammable solvents or gases should not be present in or around Type A bags.

Type B FIBC / Bulk Bag (Surface breakdown voltage of <6kV).

These bags are also made of non-conductive materials and should be used in the presence of combustible dusts with MIE of greater than 3mj — but not around flammable vapors. Type B FIBC bags are used to store and safely transport dry, flammable powders.

Type C big bags are produced from fabrics with conductive fibers at certain intervals on big bags. The bag must always be grounded during filing and unloading to prevent powerful sparks discharges. The voltage rating of the conductive fibers on the bag must be in contact with less than 107 ohms of resistance to the ground.

Type D bags are static-dissipating bags similar in use to Type C, but these bags do not require grounding. Instead the antistatic fabric itself has special additives to avoid brush discharges and incendiary sparks. Type D FIBC bags can safely store and transport flammable powders or when flammable dust or gases are present.

Wicon is the only Indonesian manufacturer holding Texene, USA’s license and rights to produce type D Crohmiq® fabric and bags.
