FIBCs – Özova Group

4 LOOP FIBCs

Bulk bags are one of the most cost-effective forms of industrial packaging. FIBCs can be designed to carry loads up to 2250 kg. Their strength, durability, and versatility have made them the packaging product of choice for manufacturers worldwide.
Available in a multitude of fabric types, styles, and sizes, our standard 4 Loop bulk bags are built for toughness. Whether you need a custom-built or off-the-shelf bulk bag solution, NASTECHS can provide an FIBC tailored for innovative packaging solutions

1&2 Loop FIBCs

1&2 Loops FIBCs are made of circular woven fabrics. At its top point the loop is wrapped and fixed with a cuff (sleeve)made of laminated fabric. It protects the loop from damage when contacting hooks and forks of lifting equipment. These bulk bags are simpler by design and economical than 4 Loop FIBCs. Different colors of sleeves are used for sorting different products and enable quicker product identification.

UN FIBCs

UN Certified Bulk Bags are used for the storage and transportation of certain hazardous materials. UN Certified Bulk Bags are designed specifically to meet the requirements set forth by the United Nations for transporting and storing hazardous materials.

There are four types of FIBCs for dangerous goods made from woven plastics:

13 H 1	–	woven plastics without coating and without liner
13 H 2	–	woven plastics, coated and without liner
13 H 3	–	woven plastics, uncoated and with liner
13 H 4	–	woven plastics, coated and with liner

Categories of UN bags

Degree of Danger	Packing Group	UN-Symbol	max. Volume
high	I	X	1,5 m³
medium	II	Y	3,0 m³
low	III	Z	3,0 m³

Classes Of UN Rated Bags

Anti Static FIBCs

Type A :

Type A bulk bags are the industry standard used for the most common applications of storing and transporting dry goods for all industries. 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. Manufactured with conventional woven polypropylene, they do not have any mechanism for dissipating static electricity and will not prevent highly energetic and dangerous propagating brush discharges
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.

Safe use for type A bulk bags:

To transport non-flammable products.
No flammable solvents or gases present around the bag.

Do not use type A bulk bags for:

Transporting flammable products.
When flammable solvents or gases are present around the bag.
Should not be used where a flammable atmosphere with a minimum ignition energy ≤1,000mJ is present.

Type B :

Type B bags are constructed from insulating fabric but have a breakdown voltage less than 6 kV. This provision prevents the risk of energetic propagating brush discharges which can ignite dust-air mixtures and flammable gases and solvent vapors. Type B bags may be used in the presence of the combustible dusts with MIE of greater than 3mJ, but only in the absence of flammable vapors of gases. Type B bags are sometimes called antistatic bags, but it should be noted that Type B only provides limited protection against static electricity and they do not provide any mechanism for dissipating static charge.

Safe use for type B bulk bags:

To transport dry, flammable powders.
No flammable solvents or gases present around the bulk bag

Do not use type B bulk bags for:

When flammable solvents or gases are present around the bulk bag

Type C :

Type C FIBCs, also known as conductive FIBCs or ground-able FIBCs, are made from non-conductive polypropylene fabrics interwoven with conducting threads forming a reliably interconnected grid of maximum 50 mm mesh size or having a distance between each other of less than 20 mm if the threads are in one direction only.

These conducting threads must be electrically interconnected as well as connected to a designated ground/earth during filling and discharging.

Safe use for type C bulk bags:

To transport flammable powders.
When flammable vapors, gases, or combustable dusts are present.

Do not use type C bulk bags for:

When ground connection is not present or has become damaged.
Resistance from any location FIBC to ground-able point

Type D :

TYPE D: Type D FIBCs are made from antistatic and static dissipative fabrics designed to safely prevent the occurrence of incendiary sparks, brush discharges and propagating brush discharges without the need for a connection from the FIBC to a designated ground/earth. Because of the charge dissipation into the surrounding area via corona discharge, the Type D FIBC can easily charge insulated conductive objects or persons standing nearby. Those objects or persons can, when contacting ground or grounded objects, cause electrostatic spark discharges capable of igniting explosive mixtures of gases or vapors. Thus, Type D FIBCs may be used with combustible dusts, but only in hazardous areas zones 2 (medium risk gas/vapour) and 22 (medium risk powder/dust) as it is allowed for FIBCs of Type B with the prerequisite that the breakdown voltage is less than 6 kV to be verified by testing. The application of a Type D FIBC in a hazardous area zone 1 (high risk gas/vapour) requires further measures decreasing its effective charge to a non-hazardous degree. For safe use of Type D-FIBCs – meeting the requirements stated above – in a hazardous area, zone 1, it must be pointed out, that all conductive objects and persons in the vicinity of the FIBC must be grounded during the filling and emptying process. This instruction for grounding is to be set forth in words on each bag. Safe use for Type D bulk bags:

To transport flammable powders.
When flammable vapors, gases, or combustable dusts are present.

Do not use type D bulk bags for:

When surface of FIBC is contaminated or coated with conductive material such as grease or other flammable and or combustible materials.
