Conductive bags
During filling and discharging of big bags, static electricity will occor due to the friction between product and fabric.
In worst case this will lead to an explosion depending on the product and the surrounding atmosphere.
Big bags are classified by their discharging ability:
Type A
No conductivity.
Type B
Ensures a breakdown voltage of less than 4 kV which prevents the occurence of propagating brush discharges. Can be used in the presence of potentially flammable dust atmospheres provided its ignition energy is greater than app. 3 mJ.
Type C
Interwoven carbon threads that are connected and grounded ensures a resistence to earth from any location on the FIBC of less than10 in 8 Ohm. Suitable for use in the presence of any potentially flammable atmosphere provided the FIBC is adequately grounded during use.
Type D
Produced of special PP-fabric which in itself is conductive without the need for grounding.
All above mentioned types can be supplied as food approved, UN-certified, quadro and/or with liner.
