Bulk bags offer an effective and affordable way to package goods, store them, and transport them, from the food and pharmaceutical industries to businesses that make gardening tools and construction equipment. The solid materials that were used by FIBC bags manufacturers in Gujarat to make the bulk bags that organizations sell are what give them their efficacy, durability, and utility. Bulk bag manufacturing takes place in high-quality facilities under intense inspection. Additionally, the inspection procedure assists in ensuring that each bag can transport goods, chemicals, drugs, and consumables in accordance with global safety requirements.
FIBC bags manufacturing process
Different steps which every FIBC bags manufacturer in India follow in the manufacturing process are
-
Extrusion
Extrusion, which melts a mixture of virgin components to create tapes with precise measurements, is the first step. Granules of polypropylene (PP), UV inhibitors, a minuscule amount of calcium carbonate, and perhaps colour pigments are used in this process.
-
Weaving
The tapes composed of PP granules are put onto weaving machines. The polypropylene fabric used to create the body of the bag in this instance is woven into the shape of a bulk bag. The material is strong enough to transport a variety of industrial products and consumables.
-
Moisture – proofing
Each bag can be made humidity resistant by laminating the cloth with a unique coating. The method that works best for bulk bags’ resistance to humidity is lamination. Additionally, bulk bags that contain granular goods and any product that shouldn’t be exposed to humidity need to be moisture proofed.
-
Cutting
First, a cutting machine is used to cut the polypropylene cloth into precise forms. Whether the technique creates sides, edges, or bottoms determines the dimensions. Accurate lengths for each cut are ensured via automatic measurement. The required cuts are made at this stage.
-
Printing
The polypropylene fabric is shaped after cutting, then fed through a printing machine. Here, the fabric is imprinted. If a business wants to print its name or logo on a line of bags, printing happens at this stage. There may be a number of colours utilised, depending on the brand.
-
Webbing
The bulk bag’s handle pieces are made during this stage. Additionally, this process involves twisting webbing material from thicker polypropylene fabric tapes. The lengths of the strips of this material are then carefully cut to match those of the bags being constructed. These strips act as the lifting loops or handles for the bag.
-
Sewing unit
Massive quantities of bulk bags are stitched together by a group of skilled workers under the watchful supervision of technical supervisors. This department is in charge of the various parts of a bulk bag, including the square and rectangular pieces of polypropylene fabric and the thicker lifting-loop strips.
-
Inspection
Quality control inspectors in every FIBC company in India evaluate each bag after sewing a line of bulk bags together to ensure that it satisfies the necessary durability and strength requirements for a bulk bag product line. Any bags with improper stitching are taken off the market.
-
Burst test
To find out if bulk bags pass the Safe Working Load (SWL) test, a random sample is put into a testing ring. Usually, this process must be carried out prior to the bulk bag’s general production.
-
Packing
After bulk bags have been mass-produced, it is time to organise and compress them into precise quantities for distribution in bulk. The bags are compressed in a bale press, allowing for efficient and orderly packing.
-
Storage
The bulk bags are transported to a storage place after being packed, baled, and finished. The bulk bags will then be distributed to various customer locations.
