Dimensions of bulk bags

Utilize your space to the maximum, reduce transportation and stock costs

Choose the dimension of a bulk bag

To accurately determine which dimension of big bags you need, you should consider following points:

• The density of the product which is packaged in a big bag (each product has a specific weight based on which one can determine which the dimension of a big bag is required)
• Specific conditions for filling and discharging a bulk bag
• If you have a fillng machine, you must choose the big bag dimension within the machine's limits
• If your customers have a limited ability to handle or discharge, you must comply with their requirements
• Product transportation and storage conditions. Width, length, and height of the vehicle which will be transporting the big bags (truck, container or train wagon, ship) play an important role in determining the dimensions of a FIBC, also the dimensions of shelves and organization of warehouse space where the big bags will be stacked is important.

Maximum use of truck space

As bulk bags are often transported by truck whose width is about 2.46 m and length 13.6 m, the most common external bases of a big bag are:

Jumbo bags on pallets

Since jumbo bags are often placed on pallets, the dimensions of a jumbo bag can also be chosen in line with the palette dimensions. For an Europallet which has a base of 80x120 cm, jumbo bags that have similar but slightly smaller size are often used. FIBC that are optimized for a Europallet are often Q-bags.

The equal length and width of a big bag (square) vs different length and width of a big bag (rectangle)

Equal sides (square)

•  A manipulator does not have to worry about which side is the right one. It is difficult to see the difference when the difference between the sides is small (eg. 91x95cm) and when there is no printing
•  You are not limited on how to grab FIBC with a forklift (Same distance for forks on both sides)
•  Underutilization of space (e.g. on pallets)

Different sides (rectangle)

•  Space can be maximally utilized (e.g. on pallets)
•  It is a little more complicated to manipulate

Individual dimensions

DIV-Trades can produce any other dimensions at your request. Even extraordinary dimensions such as FIBC of 50 * 50 * 50 cm or 140 * 140 * 240 cm are no problem.

Standard widths of a big bag

Our standard widths of PP fabrics used for the production of FIBC (external dimensions) are 70 cm, 75 cm, 80 cm, 85cm, 91 cm, 95 cm, 100 cm, 105 cm, 110 cm, 115 cm and 120 cm.

Big bag height

There is no standard big bag height so it can range from 50 cm to 250 cm. For the stability of a FIBC, it is not recommended that the height is greater than twice the shorter side. The height is determined in order to fit exactly to the needed material quantity + 10% of empty space for easier filling.

About the dimensions of big bags

What is the dimension of a big bag?

The dimension of a big bag is comprised of the width, length, and height of the FIBC body. Dimensions of inlets and outlets of big bags and loop length do not considered as a part of the dimension of the FIBC.

External and internal dimension

When determining the dimensions of a big bag, one should bear in mind that external and internal dimensions are not equal. The external dimension of a bulk bag is 4 cm larger than the internal dimension (e.g. If the external dimension is 95x95 cm, the internal dimension is 91x91 cm). The external dimension is measured from the beginning to the end of the fabric while the internal dimension is measured from seam to seam. Space which can be used for packing material is internal.

Big bag belly

When a big bag is filled with material its diameter becomes about 25 cm larger than the dimension of an empty big bag. This problem can be solved by inserting baffles to the corners of the big bag to prevent forming the so-called belly after filling. The diameter of these big bags increases only by about 10-15 cm. Read more about these so-called Q-bags.

One and two loops

Big bags with one or two loops are made from circular fabric and dimensions of 62,5 x 62,5 cm or 90 x 90 cm (other dimensions possible). These are specific FIBCs where there is no difference between the internal and external dimensions
