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 stac

ked is important.

determined in order to fit exactly to the needed material quantity + 10% of empty space for easier filling.


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.



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 100x100 cm, the internal dimension is 96x96 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.



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.
