Manufacturing Flexible Intermediate Bulk Containers (FIBC, Jumbo Bag, Big Bag, Bulk Bag or Super Sack) includes various 

type of key steps. Here in this process the PP granuels which is the basic raw material is being converted in to a FIBC Big 

Bag after undergoing various types of process. The total process involved are of 11 steps. The brief note is being below 

mentioned regarding each and every step.

Step 1 - Extrusion :

Here the virgin PP granules are being melted and made as tapes which are wound in bobbins of required size. This is the 

first stage of process which determines the tensile strength of the tape.

Step 2 - Weaving :

Extruded tape bobbins will be loaded in the Circular loom . Here the tapes will be woven to fabric of required specification 

and will be would in roll form. These fabrics will become the body fabric of the bags (FIBC, Jumbo Bag, Big Bag, Bulk Bag, 

Super Sack).

Step 3 - Coating (Optional Step) :

Polypropylene fabric is being coated for making the fabric moisture proof. This is optional process as per the requirement 

of the customer.

Step 4 - Cutting :

The woven Polypropylene fabric in rolls will be put in the automatic cutting machine and will be cut in to cut bit of required 

size. This Automatic process is adopted to get better accuracy in cut size.

Step 5 - Printing :

The body fabric will be put in to the heavy duty printing machine to make the printing impression on the fabric. This is 

step for presenting the customer logo

Step 6 - Webbing :

Heavier Polypropylene Tapes are woven in to webbing which forms the lifting loop of the Jumbo Bags.

Step 7 - Sewing :

Here all the components used to manufacture Jumbo bags are brought together along with the printed body fabric. All 

the parts are assembled to a Jumbo Big bag by highly skilled labours under the supervision of technically qualified 

supervisors.

Step 8 - Inspection :

Here each bag needs inside and outside cleaning with sticking roller.

The quality inspection of FIBC bag is to check one by one to ensure that the product is qualified before delivery. and 

electrostatic dust removal is a necessary step in the process of quality inspection of FIBC bag to thoroughly clean the 

foreign matters in each bag, such as waste pp wire, impurity, dust, etc

Step 10 - Packing :

Here the bags which has been produced will be compressed with the help of the bale press and neatly packed as per the 

requirement of the customers.
