Flexible intermediate bulk container bags are industrial packaging bags that are primarily composed of woven polypropylene (PP) fabric.
They are also called as FIBC bags, Jumbo bags or Bulk bags are designed to carry large amounts of dry flowable material facilitating the efficient filling, lifting, storage and discharge.
From that point of view, the production of FIBC bags is possible to be done in various sizes, lifting loops, filling ports, discharge spouts, liners, and fabric type, which are different from the conventional small sacks to fulfill the requirements of each industrial field.
What Does FIBC Stand For?
FIBC is the name given to Flexible Intermediate Bulk Container. Such containers are popular in sectors that involve the efficient packaging and shipment of bulk goods.
They can be designed to meet specific requirements and have a flexible construction that makes them well suited to many commercial and industrial applications.
How Do FIBC Bags Work?
The filling spout or the duffle top (open top) is used to fill FIBC bags.
The bottom construction defines the material discharge method, and integrated lifting loops enable compatible lifting equipment to lift filled bags.
The proper FIBC is compatible with the material being packed, the safe working load, the filling and unloading equipment and the storage and transportation environment.
What Materials Are Used to Manufacture FIBC Bags?
The conventional FIBC bags are mainly produced in woven polypropylene as it offers strong, lightweight and flexible packaging structure.
Depending on application, manufacturers can use:
- To wear a hat.Woven PP fabric: It is used to form the load bearing structure.
- Polypropylene lifting loops: Support lifting when designed and used within the bag’s rated capacity.
- Fabric coatings or laminations: Help control moisture penetration and improve surface properties.
- Inner liners: If a product needs a special protection then provide an additional barrier.
- Printing and identification labels: Show information about the product, handling instructions and traceability information.
The choice of material properties should be considered in terms of the application, the level of protection required, the storage conditions and relevant safety requirements.
What Are the Different Types of FIBC Bags?
FIBC bags can be made in various designs depending on the nature of the product, handling requirement and industrial application.
The selection depends on the material being packed, desired capacity, type of discharge and electrostatic and regulatory factors.
