Types of FIBC Bulk Bags

Polyethylene vs Polypropylene Bags

Our high-quality bulk bags reliably store and transport different types of dry bulk materials for various applications across industries. When these materials are discharged from the flexible intermediate bulk container (FIBC) bags, static buildup may produce an electric charge.

That’s why we manufacture all designations of UN Certified bulk bags that are made of different FIBC fabric to ensure proper static protection standards. Each of these four types of bags — Type A, Type B, Type C, and Type D — offer unique features and specific usages.

Bulk Bag Classifications

Type A Bulk Bags

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 Bulk Bags

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 Bulk Bags

Type C bulk bags are known as conductive FIBC bags and have conductive threads woven throughout the bag and are connected to tabs which must be grounded during filling and/or discharge. The threads dissipate static energy safely from the surface of the bag. Type C bags safely store and transport flammable powders or when flammable gas, dust, or vapors are present.

Type D Bulk Bags

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.
