CROHMIQ is internationally recognized as the genuine Type D static protective bulk bag packaging technology. The proven safety record of CROHMIQ is unmatched. Over 30 million CROHMIQ FIBCs have been safely used, including extensive use in hazardous flammable environments. Only CROHMIQ's FIBC technology provides a level of safety equal to a properly earthed Type C FIBC, without the risks of human error. For these reasons, leading global companies have converted from Type B and Type C bulk bags to the optimum safety of CROHMIQ FIBCs. Over 4 million CROHMIQ FIBCs have been safely reused after refurbishing. The static dissipative properties of CROHMIQ FIBCs are permanent; therefore, its performance does not decay with time nor wash off during wet reconditioning processes as happens with inferior Type D FIBCs. Grounding CROHMIQ is not required, but CROHMIQ can be safely grounded for applications that demand groundable bulk bags. CROHMIQ FIBC fabric is FDA and EU food contact compliant, including 21 CFR 177.1520. CROHMIQ FIBCs are continuously tested in a world-class testing laboratory. Over 15 years of thorough testing by the world's leading test laboratories has proven the safety of CROHMIQ’s technology. CROHMIQ complies with the latest National and International safety standards for static protective FIBCs. Worldwide technical support is available to all users of CROHMIQ FIBC.© Texene LLC 2012-2014
To ensure the continued safety of CROHMIQ® fabric, TEXENE regularly conducts tests in its safety performance test laboratory located in Summerville, SC. The most important test that proves the safety of FIBCs for use in flammable or explosive atmospheres is the incendivity, or ignition test, conducted according to the International Standard IEC 61340-4-4 Ed. 2.0: 2012. The principle is to fill the bulk bag under test with charged pellets and determine if there are any electrostatic discharges from the surface of the bulk bag with sufficient energy to ignite an approaching gas probe. The test parameters are selected to provide the severest challenge to FIBCs so as to ensure they are able to perform safely under worst case conditions.

FIBCs are classified according to one of four types. The types are defined by the construction of the bulk bag, the nature of their intended operation and associated performance requirements. The table below identifies which type of FIBC is appropriate depending on the sensitivity to ignition of the product being packaged and of the surrounding atmosphere. The sensitivity to ignition of the product being packaged, i.e. the bulk product, is defined by its minimum ignition energy (MIE). Surroundings are classified in increasing sensitivity to ignition by electrostatic discharges as non-flammable, explosive dust atmosphere or explosive gas or vapor.

Type A FIBCs are made from plain polypropylene or other non-conductive material. Static electricity is generated as products move over the inside surface of the FIBC when they are filled or emptied. As there is no static protection provided by Type A FIBC, it is essential that they are not used to store or transport combustible materials or used in flammable or combustible environments.

Type B FIBCs are similar to Type A FIBC in that they are made from plain polypropylene or other non-conductive material. And like Type A FIBC, Type B FIBC do not have any mechanism for dissipating static electricity. The difference is that Type B bulk bags are made from materials that have a low breakdown voltage to prevent the occurrence of highly energetic, and dangerous propagating brush discharges (PBD). Although Type B FIBC can prevent PBD, they cannot be considered antistatic FIBC because they do not dissipate electrostatic charge and so normal brush discharges can still occur, which can ignite flammable solvent vapors.

Type C FIBCs are conductive FIBCs. Originally they were made from entirely conductive materials. Today, groundable Type C FIBCs are more commonly made from non-conductive polypropylene interwoven with conducting yarns, normally in a grid pattern. The interconnection of conductive yarns and the connection to ground or earth are critical to the safe use of Type C FIBC. As with any manual operation, ensuring interconnection and grounding of Type C FIBC is subject to human error.

Type D FIBCs are made from static protective fabric designed to safely prevent the occurrence of incendiary sparks, brush discharges and propagating brush discharges, without the need for a connection from the bulk bag to ground or earth. As CROHMIQ Type D FIBCs protect against incendiary sparks, brush discharges and propagating brush discharges, CROHMIQ can be used safely to package combustible products and for handling products in combustible and flammable environments.
