What are bag “Types”?

Bulk bags can be “Typed” A,B,C, or D. This type of designation refers to:

Type A

Type A bulk bags are basic, all-purpose bags. No special requirements or designations for this type. No hazardous material or electrostatic capabilities. Non-flammable products only, not to be used in areas with explosive potential or around flammable gases.

Type B

Type B bulk bags have a fabric with a low breakdown voltage insulating fabric. Used in the presence of combustible dusts with MIE of greater than 3mj but not around flammable vapors. Use these bags to safely transport flammable powders.

Type C

Type C bulk bags have the capability to be electrically grounded. These bulk bags 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. Use these bags to safely transport flammable powders or when flammable dust or vapors are present.

Type D

Type D bags are static dissipating bags similar in use to Type C, but do not require grounding the bag. Instead the fabric itself has special additives which give it static dissipative qualities. Use these bags to safely transport flammable powders or when flammable dust or gases are present.
