4 Most Common Types of Anti-static FIBC Bulk Bags
More and more people are turning to anti-statistic FIBC Bulk Bags for the comprehensive protection and the peace of mind they provide.
Why need anti-static FIBC Bags?
Safety consideration
Static electricity can be generated in the processing of filling and discharging of FIBCs, in the surface of the bag fabric and in the movement of the material in filling or discharging. And in severe scenarios, electrical spark can be created and a subsequent fire or explosion could accur.
It's essential to consider static-control factor in choosing an appropriate type of FIBC Bulk Bags, especially when filling and emptying sensitive contents, and when the handling environment are present with flammable gases or vapors. In terms of anti-static property, FIBC Bulk Bags is uaually classified into 4 types: Type A, Type B, Type C and Type D. These 4 types refer to different levels of static protection of FIBCs.
Type A
Type A FIBCs is made of ordinary woven fabric and doesn't offer any anti-static function. Type A should not be used to store and transport flammable substances. The processing of filling, discharging and tranporting of the Type A Bags should be avoided to environments exposed to flammable materials, thick dusty and gases.
Dry and non-flammable materials are recommended to be stored and transported with Type A FIBCs.
Type B
For this type, the bag fabric and it's liner are generally made of non-conductive material, however the bag typically has a low breakdown voltage function, in this way most of the static electricity discharges can be eliminated. The standard parameters of breakdown voltage is < 4kV.
If the surface of Type B bag is contaminated with conductive substances such as oil, the surface could occur electrical sparks and lead to fire or explosion. Therefore, the bags should be kept clean and uncontaminated. And same as Type A bags, the processing of filling, discharging and tranporting of the Type B Bags should be avoided to environments exposed to flammable materials, thick dusty and gases.
Dry and flammable materials can be stored and transported with Type B FIBCs.
Type C
To expel electricity static, Type C FIBC Bulk Bags must need to be grounded in the processing of filling, emptying and tranportation. The bag is made of conductive fabric or interweaved with conductive threads or filaments. Type C Bulk Bag is intended developed to store and transport flammable substances, and are safe to be exposed in flammable materials, thick dusty and gases evironment in the handling and transporting processing only in condition of effectively connecting the ground.
Same as Type B, Type C Bag typically has a low breakdown voltage < 4kV.
Flammable powders and other flammable matertials are recommended to store and transport with Type C Bulk Bags.
Precaution that Type C Bags must be always grounded to get valid functionality of anti-static.
Type D
Type D Bulk Bag could be viewed as an up-graded version of Type C Bulk Bag in terms of anti-static function. The fabric material of Type D is preprocessed and could automatically dissipate the electricity charge through low energy corona discharges and no need to be grounded in the processing of filling, emptying and transportation. And Type D Bags can be safely exposed to environment of flammable materials, thick dusty and gases.
Flammable powders and other flammable matertials are recommended to store and transport with Type C Bulk Bags.
The reason of many fatal and non-fatal electrical fire incidents may lead to electrostatic discharge and shorcks in the workplace, and could cause serious mortality threats, essets loss and operational cost increase. According to relevent statistics, the injeried empolyees may take a median 10 days off to recover. One way to effectively prevent this is to use anti-static bulk bags, and the market trend is alligning with this it, the market for FIBC Bulk Bags is steadily increasing at a 7-8% compound annual growth rate.
