FIBC Bags known as Flexible Intermediate Bulk Containers (FIBC) are frequently used for the storage and transportation of dry goods. The material used to make these bags is woven polypropylene, a thermoplastic polymer with numerous industrial and consumer applications. In this post, we’ll give a straightforward explanation of how FIBC bags are made.
Preparation Of Raw Material
Preparing the polypropylene resin pellets used as the raw material is the initial stage in making FIBC bags. In an extruder, these pellets are melted after being put into a hopper. After being pressed through a die, the melted polymer forms long, uninterrupted strands of polypropylene tape.
The fabric for the FIBC bags is then made by weaving the continuous polypropylene tape strands on a loom. To weave a sturdy, long-lasting fabric, the strands of tape are interlaced at correct angles.
Making cuts and sewing
The FIBC bags’ desired size and shape are then cut from the woven cloth. The bag’s body is made by folding and sewing together the cut fabric. During this operation, the lifting loops and other elements like filling and discharge spouts are also attached.
Printing & Quality Control
Printed logos, labels, and other details are applied to the bags after they have been stitched. The bags are then subjected to a quality control procedure where they are examined to make sure they adhere to the necessary requirements and standards.
The preparation of raw materials, weaving, cutting and stitching, printing, and quality control are all phases in the production of FIBC bags. The end result is a sturdy, long-lasting bag that is perfect for storing and transporting goods.
