How Circular FIBC Woven Bags Are Made

A woven circular FIBC bag is a tubular bag made from a single piece of polypropylene fabric that’s woven in order to eliminate vertical seamless, so what you have is a smooth, cylindrical shape, perfect for even weight distribution and improved durability. But, how are these bags made?

A natural and circular woven fabric supplier for these bags, in collaboration with their manufacturers, would make this container using a fabric woven on a circular loom. Then, it will be cut to its proper length for a certain bag heigh, therefore eliminating the vertical seams that each side may have. As for the bottom, it is cut following a circular shape, then sewn on the fabric’s body.

Main Benefits of Circular Bags 

The benefits of these circular FIBC bags are plenty, from their sift resistance to their affordability.

1. Sift Resistance 

First, these bags provide unparalleled sift resistance due to their seamless construction, which is necessary to prevent material loss during handling and transport.

2. Durability

Second, they are very durable. This ensures they are able to perfectly withstand heavier loads and harsher conditions, minimizing risks of product damage or worse, bag failure.

3. Cost-Efficiency

These bags are affordable and cost-efficient. This is since they reduce the need for another layer of bag or packaging. Plus, you may also re-use or recycle these bags, lowering costs on overall logistics and environmental expenditures. 

Alongside easy handling, opportunities for automation, and high load capacity, these benefits make circular FIBC bags reliable and effective for industries that really deal with bulk dry materials.

How FIBC Flat Woven (U-Panel) Bags Are Constructed

Then, you have the flat woven U-panel bags. A woven flat FIBC bag, also known as your U-panel FIBC bags, is one of those types of FIBC bags commonly used for the storage and transport of large quantities and amounts of materials, just like the circular type. 

However, these bags are constructed using just a single piece of fabric, folded and sewn to make U-shaped panels, providing enhanced stability and capacity, compared to the rest of those types. 

Benefits of U-Panel Bags

Here are the benefits of a U-panel FIBC bag: 

1. Shape

The design of these bags allows for more efficiency during handling, which optimizes the space and reduces the risk of damage while transporting items across.

2. Strength

This fantastic shape also is responsible for its unwavering stability, especially when filled with very heavy or bulky materials, such as in mining and construction. This design prevents tipping, ensuring safe handling all the time. 

3. Cost-Efficiency 

Just like their counterparts, U-panel FIBC bags are also cost-efficient. This is due to their durable and lightweight construction, reducing transportation and labor costs. 

Plus, they are also very customizable, laden with features, from liners to loops, to meet specific standards and requirements.

4. Customizability + Sustainability  

Lastly, these bags offer great opportunities for recycling, contributing to eco-friendliness, customizability, and several years of cost savings. 

These benefits and flexibility make them highly suitable across a wide range of industries.
