Fibc Bag Calculation

Fibc Bag Calculation

FIBC bags, also known as bulk bags or jumbo bags, are large containers used for storing and transporting bulk materials. They are commonly used in industries such as agriculture, construction, and mining due to their versatility and cost-effectiveness. When calculating the dimensions and specifications of FIBC bags, several factors must be taken into consideration to ensure they meet the specific needs of the material being stored or transported.

Weight Capacity

One of the most important factors to consider when calculating the specifications of an FIBC bag is the weight capacity it must be able to handle. This is typically measured in terms of safe working load (SWL) and is determined by factors such as the strength of the fabric used, the stitching method, and the number of lifting loops. It is essential to calculate the weight capacity accurately to prevent overloading, which can lead to damage or failure of the bag.

The dimensions of an FIBC bag play a crucial role in its functionality and efficiency. The size of the bag should be determined based on the amount of material it needs to hold, as well as the space available for storage or transportation. Factors such as the width, length, and height of the bag should be taken into consideration to ensure it can be safely and efficiently handled by machinery or personnel.

Type of Fabric

The type of fabric used in an FIBC bag is another important consideration when calculating its specifications. The most common types of fabric used in FIBC bags are polypropylene and polyethylene, each offering different levels of strength, durability, and chemical resistance. The choice of fabric should be based on the specific requirements of the material being stored or transported, as well as the conditions in which the bag will be used.

Top and Bottom Construction

The top and bottom construction of an FIBC bag can significantly impact its overall performance and durability. Factors such as the type of closure (spout, duffle, or flap), the presence of filling and discharging spouts, and the type of bottom (flat, spout, or discharge) should be carefully considered when calculating the specifications of the bag. These elements can affect the ease of filling and discharging the bag, as well as its stability during storage and transportation.

Lifting Loops

The number and placement of lifting loops on an FIBC bag are essential for ensuring safe handling and transportation. The loops should be positioned strategically to distribute the weight of the bag evenly and prevent damage or failure during lifting. The strength and durability of the loops should also be considered to ensure they can withstand the weight of the bag without breaking or tearing.

Testing and Certification

Before using an FIBC bag, it is essential to ensure that it has been properly tested and certified to meet industry standards for safety and performance. Factors such as static load testing, dynamic load testing, and safety factor calculations should be conducted to verify the strength and integrity of the bag. Certification labels should be displayed prominently on the bag to indicate that it meets the necessary requirements for safe and efficient use.


Calculating the dimensions and specifications of an FIBC bag is a complex process that requires careful consideration of various factors such as weight capacity, dimensions, fabric type, top and bottom construction, lifting loops, and testing and certification. By taking these factors into account, you can ensure that the FIBC bag you choose meets the specific requirements of your material storage or transportation needs, providing a cost-effective and efficient solution for your business.
