With coal being a major source of energy, South Africa’s mining industry is a key economic pillar. However, there may be practical difficulties in storing and moving this valuable resource in an efficient and safe manner. 

Bulk bags, also called flexible intermediate bulk containers (FIBCs), are the ideal packaging solution for mines in South Africa. They are extremely durable, lightweight and affordable – offering a sustainable way to transport bulk quantities of coal and ore in and around the mines. 

Custom Bulk Bags is a reputable manufacturer and supplier of FIBCs. We produce up to 3.5 million bulk bags per year and our products can safely hold between 500kg and two tonnes of material per bag. We offer several UN-certified designs and attachments, making our products fully customisable to meet your needs.

Advantages of bulk bags for coal mines

For South African coal mines, bulk bags provide a number of benefits over conventional packaging solutions, like loose loading or rigid containers. Firstly, FIBCs offer increased safety. They are made from woven polypropylene tapes, which is extremely strong but maintains the flexibility needed to carry ore and irregularly-shaped materials. Bulk bags lower the possibility of workplace mishaps and contamination of the environment.

Next, loading and unloading are simple with bulk bags. With specialised filling equipment, they can be filled fast, and their strong lifting loops make transfer simple and labour-efficient. This results in lower labour costs and quicker turnaround times.

Bulk bags also enable decreased storage space. They take up very little space when not in use because they can be folded flat. Even when filled, bulk bags can be stacked neatly on top of one another, maximising the available space taken up for storage. Mines with smaller storage facilities will especially benefit from this.

FIBCs can be ordered with customised labels and clear pouches for documentation. Coal stock can be efficiently tracked and inventoried with ease thanks to the easy labelling and identification of bulk bags. A seamless supply chain is ensured and stock management is made simpler by this transparency.

Superior quality polypropylene fabric that has been UV-stabilised is used to make Custom Bulk Bags products. This guarantees that the bags will withstand the varied weather in South Africa and shield your coal from deterioration and moisture damage.

When weighed against alternative packaging products, bulk bags prove to be an affordable solution. Over time, the reusability and lower initial input costs result in substantial savings for mines. Furthermore, when compared to solutions for disposable packaging, their reusability minimises waste.

Selecting the best bulk bag for your coal 

Choosing the best bulk bag for South African coal mines is essential, especially with so many alternatives available. Here are some important things to think about:

  • Coal type – The weight and flow properties of various kinds of coal, such as bituminous or anthracite coal, may differ. To make it simpler to empty the bag of finer coal particles, pick a bag with a weight capacity that works for you and take into account the choices of discharge spouts.
  • Size and capacity – Bulk bags are available in a range of sizes, with a typical capacity of 500kg to 2000kg. Make your selection based on how much coal you usually handle per bag.
  • Safety features – Choose bulk bags with integrated discharge spouts to reduce dust production during unloading, as well as safety loops for safe lifting and handling. Make sure the bulk bag’s safe working load (SWL) is greater than the maximum weight of coal you want to move or store.
