The good and bad quality of the container bag is crucial.
FIBC is a kind of flexible container bag. Flexible Intermediate Bulk Containers - Abbreviation: FIBC, also known as gold diamond tonnage bag, space bag, container bag. Container bags (tonnage bags, FIBC) are mainly used to ship some scattered, powder and granular materials, with the crane will be able to achieve unitized transport. Container bag is a flexible transportation packaging containers, widely used in food, grain, medicine, chemicals, minerals and other powdery, granular, lumpy items of transportation packaging, belonging to the container unit apparatus.
Have you encountered the problem of FIBC seams tearing resulting in transportation leakage?
Our Big Bag Sewing Machines from KINGMAX use stitching technology, as well as improved seam strength, to reduce the amount of feed by using an alternative top feed, helping you to minimize the risk of cargo damage claims and enhance the output of your FIBCs.
However, it is important to understand that not all FIBC products are created equal. There are different types of FIBCs, each designed to meet specific requirements and unique challenges.
There are different styles and types, each designed to meet specific requirements and address unique challenges, and 5 different types of FIBC bags:
1. U-Panel Bulk Bags
The U-shaped bag consists of two panels formed by two seams sewn on either side to form a "U" shape. u-shaped FIBCs are recognized as the global industry standard and are the most popular FIBC shape. This structure gives the bag a high load capacity.
The main advantages are as follows:
- Excellent ability to carry heavy loads.
- Fewer weak points at the bottom of the bag.
- Vertical side seams give objects a square appearance.
- Suitable for sieving fine items.
- Light weight.
- Resistant to dust, moisture and leakage.
- Resistant to acid corrosion.
The main applications include:
- Transporting cement.
- Transporting chemicals.
- Transporting grains and minerals.
2. Circular Bulk Bags
Round pouches, also known as tubular pouches, consist of two main bodies: the body tube and the base. The body tube is made of a seamless tubular fabric that forms all sides of the bag, allowing for stitching only at the top and bottom of the bag. Although the fabric is tubular, when filled, a round bag will still look somewhat like a square bag.
They are mainly used for storing: chemicals, food, grains, legumes, cement, minerals, sugar, clay, fertilizers, dyes, salt, seeds, flour, resins, nuts, rice, detergents, plastics, pharmaceuticals, refractory products and more!
Key benefits include:
- Resistance at low temperatures.
- Pharmaceutical and food grade.
- Remote release of goods from the bottom of the bag without removing the bag from the ground.
3. 4-Panel Bulk Bags
The top and bottom panels of a Four-Interface Bulk Bag ( FIBC ) are also sewn together and have seams running the length of the four separate pieces of fabric that make up the body of the bag. Four-sided panel bags are ideal for stacking because they hold their shape better than other types of bags.
Key benefits include:
- Great for storage and transportation due to their ease of stacking.
- More bags can be stored while saving storage space.
- Perfect for industries that primarily need to package, store and transport solid and uniformly shaped products.
- Even finer types of substances can be easily transported due to the square design of the bags and stronger materials.
4. Baffled Bulk Bags
More specifically, baffles are fabric panels or strings sewn into the four corners of a large bag that keep it square when filled. Without baffles, the types of construction listed above may bulge or bulge at the sides when filled.
Key advantages include:
- Mesh baffle bags can be filled faster because the material can flow freely into the corners between the meshes.
- This also allows the bag to drain faster and cleaner as there is less debris stuck in the corners.
- Depending on your merchandise, maximizing quantity may also have added value.
- In some cases, up to 10% extra volume has been added to the same size bag, allowing for more merchandise to be shipped efficiently or potentially reducing the bag size. These may enhance the benefits of a sustainable program.




5. Single Loop and Double Loop Bags
Single-ring and double-ring bags are made from single-tube fabrics and are widely accepted as more cost-effective than traditional four-ring bags.
Key benefits include:
- Loading efficiency
- Cost savings
- Customized features to meet actual needs
