FIBC Bulk Bags Manufacturing Process: The Art of Crafting FIBC Bags

FIBC Material: What Are Bulk Bags Made Of?

Before we delve into manufacturing, let’s understand the materials that make up d.a.pak FIBC bags. 

These bags are primarily constructed from polypropylene fabric, a strong, durable, and thermoplastic polymer. Here are some key points about FIBC material:

• Polypropylene (PP): This material is resistant to moisture, chemicals, and UV radiation. Due to its robustness, it’s an excellent choice for bulk bags.
• Coatings: Some FIBC bags have additional coatings for extra protection.
• Lifting Loops: FIBC bags feature woven polypropylene lifting loops, making them easy to handle.

Types of FIBC Bags:

Different FIBC bag types cater to specific needs:

• Type A: No electrostatic protection.
• Type B: Surface breakdown voltage of less than 6kV.
• Type C: Electrically conductive or groundable.
• Type D: Static dissipative.

The FIBC Bags Manufacturing Process

Now, let’s walk through the step-by-step process of creating these versatile bags:

1. Extrusion:

   • The journey begins with feeding polypropylene (PP) resin and other additives into an extruder. This process produces PP tapes of varying thickness and width.
   • The melted resin forms PP sheets, which are then stretched by rollers and cut.

2. Weaving:

   • The PP tapes are wound onto bobbins to start the weaving process.
   • Special looms weave the fabric, creating either circular-shaped bags or U-panels for different FIBC bag styles.

3. Vacuuming:

   • Vacuuming removes any loose fibres or debris from the woven fabric, ensuring a clean surface.

4. Lamination:

   • Some FIBC bags undergo lamination, where additional layers are added for reinforcement or barrier properties.

5. Printing:

   • Manufacturers can print essential information (such as safety instructions or company logos) directly onto the bag fabric.

6. Cutting:

   • The woven fabric is cut into panels according to the bag design (rectangular, circular, or U-panel).
   • Precision matters here to ensure consistent bag dimensions.

7. Sewing:

   • Skilled workers sew the panels together, creating the bag’s body.
   • They also attach lifting loops and any other necessary components.

8. Final Testing:

   • Each FIBC bag undergoes rigorous testing.
   • Stress tests include drop and jerk forces to assess the bag’s integrity during transport.

What Features Make d.a.pak FIBC Bags So Functional?

d.a.pak’s FIBC bags are widely used across various industry sectors. 

They are commonly employed in industrial environments like processing facilities and warehouses, as well as in construction and mining operations. 

These bulk bags serve both as practical transportation vessels and excellent storage solutions. Their compact design makes them particularly suitable for space-constrained areas. 

Even large warehouses can benefit from replacing rigid containers with flexible FIBC bags.

Unlike standardised options, FIBC bags come in a variety of designs, catering to specific requirements. 

Businesses dealing with heavy loads and bulky items frequently rely on our FIBC bags for storage and transportation. 

However, these bags are versatile enough to handle finer materials such as granular products or powders.

Moreover, d.a.pak FIBC bags enhance businesses’ safety credentials. FIBC bags are trusted in industries like chemical manufacturing and pharmaceuticals. 

Safety-focused bags for these sectors undergo rigorous performance testing to meet stringent requirements.
