Manufacturing Flexible Intermediate Bulk Containers (FIBC, Jumbo Bag, Big Bag, Tote Bag, Bulk Sack or Super Sack) involves various types of key steps along with our skilled operation performed. Here in this process the PP granuels which is the basic raw material is being converted in to a FIBC Bag after undergoing various lines of process. The total process involved are of 11 steps. The brief note is being below mentioned regarding each and every step.
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.
Extruded tape bobbins will be loaded in the Circular weaving machine or Flat weaving machine. 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, Tote Bag, Bulk Sack, Super Sack).
Polypropylene fabric is being coated for making the fabric moisture proof. This is optional process as per the requirement of the customer.
The woven Polypropylene fabric in rolls will be fed 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.
The cut bits that is the body fabric will be fed in to the heavy duty printing machine to make the printing impression on the fabric. We are equipped with heavy duty printing machine, which gives the best impression with maximum of three colours.
Heavier Polypropylene Tapes are woven in to webbing which forms the lifting loop of the Jumbo Bags.
Here all the components used to manufacture Jumbo bags are brought together along with the printed body fabric. All the gathered parts are assembled to a Jumbo bag by highly skilled labours under the supervision of technically qualified supervisors.
Here each and every Jumbo bag we manufacture will be inspected by a technically qualified person from the quality control department to ensure that each and every bag delivered from Virgo is of good quality.
Random Jumbo bags will be selected from a particular lot and will be tested in the testing ring to ensure the Safe Working Load of the bag is achieved. Generally this test is conducted with the sample bag before commencing the production. But after completion of the production also, random samples are taken for burst test to ensure the Safe Working Load.
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.
Once the Jumbo bags are baled, it will be immediately shifted to a clean storage room, from where the dispatches are effected.
