Project Description
During the last 30 years, the use of “Flexible Intermediate Bulk Containers” (FIBC) increased because of the economic benefits, simplicity of filling procedure, transportation, storage saving and discharging convenience in comparison with small bags.
The quality of our products and our customer service has made us a leader not only in the Middle East but worldwide. Our vertical integration in Manufacturing from Extrusion to baling gives us a first class standard for consistency and reliability.
4 loop fibc’s – standard big bag
FIBC’S are one of the most cost effective and ideal types of packaging for shipping and storing dry bulk products. They can produced from either tubular or flat polypropylene (PP) woven fabrics. These fabrics can be both coated or uncoated and vary in different weights depending on the requirements of the Safe Working Load (SWL) & Safety Factor (SF).
An FIBC can be as simple as an open top with a flat base used commonly within the building industry . Also as a high tech unit produced within a clean room production environment to be used within the food & pharmaceutical industries.
SWL / SF (Safe Working Load / Safety Factor):
These units indicate the maximum weight-bearing capacity of the FIBC related to a nominal weight and the linked safety factor. Especially for potentially hazardous goods these indications are vital as cracks have to be avoided under all circumstances. According to the EFIBCA standards the following categories are used: single trip, standard duty as well as heavy duty.
Dust proofing: The characteristics of the good to be transported are the guideline for the choice of the so-called “dust proofing”, which of course has to be a different one for coarse-grained material compared to fine, almost liquid powder should be used here in order to avoid leakage of the contents.
Coating:
By means of coating the contents of the FIBC is protected from air and humidity. Moreover leakage of the product is prevented. One way of enhancing the surface of the FIBC, providing it with more stability and protection, is the coating of the fabric. Coating is achieved by applying a thin film onto the PP strips
UV protection:
Due to the characteristics of the basic material (polypropylene) it is not advisable to store the FIBC in the sun without protection over a longer period of time. However, for limited periods in which sun radiation is unavoidable it might be useful to enhance the material with a UV stabilization so that the contents stays safely packed.

Q big bag
Design is constructed utilizing inner baffles which help to maintain the cubic form once the FIBC has been filled. These baffles are manufactured specifically to allow the material to flow into the corners of the bag. Because of this design and cubic shape of the Q bag which requires less storage space and reduces transportation costs 25% up to 30% .
Conical Bag
Is designed specifically to assist in complete discharge of contents, which are slightly sticky, like brown sugar.
To facilitate use and transportation of the bag, different options are available for closure, filling, discharging and lifting.
Conductive UN Big Bag Type
Some bulk materials can create electrostatic energy during filling and discharging, If , there is a flammable dust or gas present within the atmosphere during the filling and discharging process, there is a risk of fire or explosion. To prevent this hazard, a conductive FIBC’s is the ideal solution. Conductive FIBC’s are also classed as Type C big bags. The conductivity of these units is usually provided by carbon tapes which are woven into the fabric and the webbing. Silver tapes are used instead of carbon for food applications. The body construction of the FIBC can be produced out of a flat or circular fabric either coated or uncoated. Conductive liners are also available for use if waterproof applications are required. UN big bags have a unique coding system, this system explains the characteristics of that particular big bag. This coding must appear on two opposite sides of the big bag for clear identification.
| FIBC Type | Type A | Type B | Type C | Type D |
|---|---|---|---|---|
| Description | No protection against electrostatic discharge. | Can prevent propagating discharge. Type B’s are similar to Type A’s, but with a thin coating which results in a breakdown voltage of less than 6 kV . | Grounded during filling and discharging to safely dissipate static electricity. Type C’s have an interconnected grid of conductive threads and grounding tabs. | Static charges are dissipated by the corona effect, and grounding of the FIBC is not necessary. Type D’s have antistatic fabric with permanent dissipative threads. |
| Application | Non-combustible products in non-flammable surrounding. | Certain flammable products when not filled or discharged in an explosive gas or vapor atmosphere | Certain flammable products and in the presence of flammable gases or vapors with ignition energies ≥ 0,14 mJ. | Certain flammable products and in the presence of flammable gases or vapors with ignition energies ≥ 0,14 mJ. |
Use of Antistatic FIBC
| Bulk Product: MIE (Minimum Ignition Energy) of Dust | FIBC Type for Different Surroundings | ||

MIE < 3 mJ | C, D | C, D | C, D |
Loop FIBCs – available with many top and bottom configurations as customer demand
Advantages of FIBC’S
- Low cost of packing with regard to the filling capacity.
- Quick filling and discharging, so loading and unloading times are reduced.
- Pallets are not necessary as they can be lifted by their loops.
- Space saving as they are stackable.
- Can be used as final and intermediate storage even in an open area because they are UV-stabilized.
- Water and dust proof designs due to inside PE liner or fabrics laminated; hence, stored materials are protected from outside humidity.
- Can be printed on both sides.
- Optional PE pockets for identification documents.
- Can be used single or multi trips.(optional)
