Custom Bulk Bag products offer numerous advantages to farmers, chemical manufacturers and businesses needing to store or transport large quantities of product. We manufacture up to 50 000 flexible intermediate bulk containers (FIBCs) every week and they can be ordered to hold specific capacities. However, the actual volume of material that our bulk bags can store will depend largely on the materials themselves and the size of their grains or particles.
A two cubic metre bulk bag will be able to hold that volume of sand, but it may only be able to carry one cubic metre of stone. The larger the grain size of the material, the less volume will be able to be stored in a bulk bag. Custom Bulk Bags are manufactured in accordance with strict international standards and we have the ability to produce up to 3.5-million bulk bags per year.
Custom Bulk Bags come in various sizes
The volumetric capacity of our bulk bags vary between half a cubic metre and two cubic metres. Our products have the ability to hold between 500kg and two tonnes of material with a minimum safety factor of 5:1, which means that they can hold at least five times their intended load without breaking. The dimensions of a bulk bag do not always equate to the volume of product they are able to store.
Custom Bulk Bags will take into account the effect of bulging when calculating capacity. When the sides of the bulk bag extend outwards as a result of the pressure of the product filling the bag, then its capacity can be slightly increased. This effect can be predicted and is relatively safe as the polypropylene fabric of the bulk bag can withstand bulging due to its sturdy and flexible nature.
As bulging causes the bag to expand beyond its expected dimensions, it can hold a slightly bigger capacity than expected. For instance, a one cubic metre bag could hold just over one cubic metre of fine-grain material. Our capacity indications may take bulging into account, although they generally follow the standard volume calculation of width multiplied by length multiplied by height.
Choosing bulk bags for capacity
Our customers have the option to place an order for standard bulk bags or they can choose to order custom dimensions in bulk. This will allow the client to tailor the capacity of their bulk bags. We suggest changing the height of a FIBC if more capacity is needed, rather than the length or width as square bases allow for easier storage and transportation.
The footprint of bulk bags is usually standardised as this ensures that they will fit onto wooden pallets properly and take up a known area of floor space. This helps with shipping and storage. Adding height will ensure that the bulk bags will still remain convenient for pallet storage and transport, but increase the capacity at the same time.
It is important to consider the volume of product that can fit into bulk bags, weight limitations and how expanding the dimensions of the FIBC can affect storage and transport. We are able to provide customers with guidance on sizing and capacity. Custom Bulk Bags will also clean and refurbish bulk bags for reuse, which is great for the environment as our products are fully-recyclable.
