. Type A bulk bags-Type A FIBCs are made of plain-woven polypropylene and
other non-conductive fabrics. Static electricity is generated as products move
over or rub against the inside surface of the bulk bag when they are
filled/emptied. There is no static protection provided by Type A FIBCs.Type A
bulk bags can be used to safely transport non-flammable products. There
should not be any flammable solvents or gases present around a Type A FIBC.
. Type B bulk bags-Type B FIBCs are similar to Type A bulk bags in that they are
made of plain-woven polypropylene fabrics or other non-conductive material.
Also, like Type A bulk bags, Type B bags do not have any mechanism for
dissipating static electricity.The difference between Type A & B FIBCs is Type B
are made from materials that have a low breakdown voltage to prevent an
incident where highly energetic, and dangerous propagating brush discharges
occur. Although Type B bulk bags can prevent propagating brush discharges,
they are not considered anti-static bulk bags because they do not dispel an
electrostatic charge.
. Type C bulk bags-Type C FIBCs, also known as conductive FIBCs or ground able
FIBCs, are made from non-conductive polypropylene fabrics interwoven with
conducting threads traditionally sewn in a grid pattern. These conducting
threads must be electrically interconnected as well as connected to a
designated ground/earth during filling and discharging. This connection to the
ground/earth during filling and discharging is imperative to the safe use of
Type C bulk bags.
