Importance Of Static Protection In FIBC Bags
At the time of handling of sensitive powders or any other inflammable objects or filling and discharging in the presence of flammable gases or vapours, it is extremely essential to have astatic protection. This is for the prevention of a fire or any catastrophic explosion. This is exactly where the anti static FIBC bags comes to the rescue. These bags offer static protection either in the form of Type C or Type D bags. So, let us read through to find out more about the importance of static protection in FIBC bags.
Type C FIBC Bags
The Type C FIBC bags which are also referred to as the conductive FIBC bags are made up of a conductive fabric. This particular fabric is woven with the conductive threads or tapes unlike the standard propylene fabric. These fabrics can be unidirectional in which the conductive threads or tapes are in a stripe pattern or they can also be bidirectional in which the conductive threads or tapes are in a grid pattern.
The construction of these bags with the interconnection of conductive fabric and grounding tabs allows the charges from both inside as well as outside to be collected on a continuous basis. Before filling of discharging, it is important to attach a grounding wire to the grounding tab. The electrostatic charges are able to dissipate through the conductive fabric and they are discharged with the help of the grounding tab in to ground. Now when properly grounded, these conductive bags help in the prevention of electrostatic discharge like brush discharges, propagating brush discharges and incendiary sparks.

Type D FIBC Bags
The Type D FIBC bags which are also referred to as the static dissipative FIBC bags are made up of a static protective fabric. This particular fabric is woven with threads that are static dissipative in nature. The electrostatic protection in these types of bags is provided by the safe dissipation of charges through the fabric into the atmosphere directly. This process is known as corona which is actually a form of electrostatic discharge but it is of low energy and is not incendiary to the atmospheres that are explosive or flammable. In case of the Type D bags, grounding is not required.
